Title
Sugar water versus salt water: What effect did they have on seed germination?
Purpose
The purpose of this experiment was to figure out what types of water would have an effect and what that effect would be on seed germination.
Background information
Plants need nutrients to survive. These nutrients can include nitrogen, calcium, phosphorus, magnesium, sulphur and iron. The plant absorbs these nutrients through the roots from the soil. These examples aren’t the only things plants need to survive though. They need things like water, sugar, and salt. There are many ways that the plant can get its sugar. Photosynthesis within the leaves and the water intake from the roots. The roots cannot make the sugar, but can take in water that contains

Although the plant can become dependant on the sugar in the water, the plant will germinate and grow faster than usual. Salt can have the same effect, although the quantity that is essential to survival is far less. Certain amounts of these can accelerate growth, stop growth, and even kill the plant. That is the purpose of this experiment; to see if the effects of the salt and sugar on the plant being tested.
Hypothesis
If the seeds are watered with sugar water, then the germination and growth will be accelerated

Summary of Data
There are quite a few trends shown within both the graphs and the pictures. The graph shows that the sugar water accelerated the seed germination greatly. The graphs also showed that none of the seeds that received salt water germinated at all. The pictures showed later on that the seeds who had sugar water actually grew taller than the ones that recieved regular
Two members of the group were instructed to visit the laboratory each day of the experiment to water and measure the plants (Handout 1). The measurements that were preformed were to be precise and accurate by the group by organizing a standardized way to measure the plants. The plants were measured from the level of the soil, which was flat throughout all the cups, to the tip of the apical meristems. The leaves were not considered. The watering of the plants took place nearly everyday, except for the times the lab was closed. Respective of cup label, the appropriate drop of solution was added to the plant, at the very tip of the apical meristems.
Although, this experiment is not concluded outdoors, it is provided with efficient light that promotes growth. It’s provided with soil, seed, fertilizer, water and NaCl solutions, to test how salinity effects plant growth.
We used wheatgrass were 40 wheatgrass seeds, two empty pots, soil, and water. We first added soil for both pots and 20 wheatgrass seeds in each pot. My partner and I decided that we label pot one experiment which is “sugar and water” and pot two control which is “water” only. The experiment was for almost four weeks we had to make sure both get the same room temperature and water, so we can see the results after this amount of time. Both pots had same room temperature so both can have the same amount of sunlight also, the same amount of water which is a glass of water from the sink once a week. In the experiment pot we added a glass of water with one teaspoon of sugar and the control pot glass of water. Every week we used to see both pots grow almost the same. At the end of the experiment, my partner and I measured the length for both plants and we recorded the average for each plant, so we can know the rate of growth
With sugar the plants grew as much as the plants without the variable consistently. With sugar some of the plants shrunk a little bit while others grew way bigger than they were before. One of our plants grew 7 cm over one period of time while another one of our plants shrunk 2.5cm at once. At 19 days the plants average height with sugar was 10.2 cm while the normal plants grew to 16 cm in 19 days. I think this is partially due to the slow start the normal plants had before we added in sugar as a variable. The plants stayed at the 1 cm range for 2-3 days before finally hitting 2.3 cm. When we finally did add sugar our plants shot up and the average height went from 2cm to 5cm and the plants started growing at a normal rate. Another reason why the plants could have grown so slowly was because of the sugar. The sugar made the plants grow fast for 4-6 days, but it also slowly started killing the plants. This explains why some of the plants started shrinking when we added sugar as a variable. While some of the plants shrunk when we added sugar, some of our plants grew 7 cm at a time, 6cm at a time. The leaves of our plants also wilted and died. Most of our plants are wilting as well which could be because sugar affects the roots of the plants and prevents them from growing well for
Hypothesis 2: If different de icing techniques are used, then sodium chloride will have a larger negative impact on the growth of Tall Fescue grass because salt dehydrates plants.
Initially, all people think of sugar in foods as a sweetener, but what they do not recognize is that it is used to preserve food. Such as: jams and canned fruits. Also sugar thickens the texture that makes liquid much better. Sugar is used around the world for bakery products and soft drinks. Furthermore, sugar is used in pharmaceutical industries, it is a common knowledge that sugar is a medicine that treats people with low blood sugar, also for diabetics with insulin intake; to balance sugar levels. In addition, sugar is a rehydration source that prevents dehydration. Additionally, sugar is used in the production of fabrics. In summary, sugar without a doubt is an important commodity because of these uses and because of its
The research I have made is that it would take awhile to see what will happen to the avocado seed because it takes awhile for a avocado seed to grow. I will use different substances to see how long it would take for a avocado seed to grow in these different substances. My four substances are soil, sprite, water, and redbull (regular) to see how tall it would grow in each different substance. I think the avocado seed will grow faster in water then all the other substances that I am going to use. The reason I think the avocado seed will grow in water the fastest is because the water will get into the avocado though the bottom and help its roots grow.
The hypothesis for this experiment was, If three different types of waters (saltwater, fresh water, tap water) are tested, then the liquids won’t evaporate at the same rate and tap water will evaporate at the fastest rate because it won’t have any non-volatile substances to hold it back from evaporating.
Sugarcane is an important industrial crop for the tropical and subtropical region of the world. It is produced in more than 100 countries, with global production of 174 million tonnes sugar. It accounts for about 80 percent and sugarbeet for about 20 percent of total sugar produced (FAOSTAT, 2008). In 2010, 1,682 million metric tonnes (MT) of sugarcane were produced worldwide in a total area of 23.8 million hectares (ha). Brazil is the largest sugarcane producer, contributing with 40% of the world production (719 MT) followed by India (278 MT), China (111 MT), Thailand (68 MT), Pakistan (50 MT), Colombia (38.5 MT), Australia (31 MT), Argentina (30 MT), United States (27.5 MT), Indonesia (26.5 MT) and the Philippines (23 MT) (FAOSTAT, 2011). India rank second among the sugarcane growing countries of the world in both area and production. Globally it is cultivated over an area of 20.1 million hectare, with annual production of 1381.1 million tonnes and productivity of 65.5 tonnes per ha. In India sugarcane is cultivated over an area of 4.36 million ha, with an annual production of 281.8 million tonnes and productivity 64.6 tonnes per ha. Uttar Pradesh, Maharashtra, Karnataka, Tamilnadu and Andhra Pradesh are the important sugarcane
This experiment was used to see the effect of salt water on the algae in the freshwater tables. The effect of salt water on algae will make the algae decrease in number. The algae were used as an indicator organism to give an idea of pollution concentrations. (Colgan, 33) Salt water can cause many problems if the salt water should enter the freshwater ways. This salt water can contaminate the aquifers and drinking waters of the world. This idea is backed up in Spatafora’s saltwater intrusion paper “When this occurs, it will move the saltwater freshwater interface inland, resulting in a higher saline concentration in the aquifers' water, rendering it useless for human consumption, unless it is treated.”(Spatafora, 2008) Not only can the saltwater effect the drinking water this water can also not be used for irrigation as seen in F. Lugoli’s article about the contamination of southeastern Salento’s groundwater “The results indicated widespread pollution from salt and microbial contamination. Contamination from faecal microorganisms posed a significant risk of human infection in 100% of samples. Furthermore, the water was unsuitable even for irrigation in a high percentage of cases (31.8%), which is of considerable significance given that agriculture is one of the most important economic activities in the area under study.”(Lugoli, 2010) The salt water can also kill the plants, algae, and ultimately the animals that use that water for water and food. The rising amounts of saltwater can cause plants to die as seen in Winn’s Saltwater Intrusion and Morphological Change at the Mouth of the East Alligator River, Northern Territory article “Significant morphological change has occurred since 1950, with the tidal creek extending 4 km inlan...
The longevity of the flowers was determined by observing the average days taken for the two stalks of cut flowers to wilt or shrivel within 14 days in different holding solutions. The tap water holding solution will be the control in this experiment. The purpose of sucrose solution in this experiment was to provide respiratory substrate and increase the longevity of the flowers. It is expected that the cut flowers in sucrose holding solution would have better longevity compared to the tap water holding solution. The results obtained are concordant to the theory as all cut flowers in sucrose holding solution have longer average days to wilt or shrivel. Coorts (1973) suggest that by supplying cut flowers with exogenous sugar such
The purpose of this lab was to learn about transpiration and to determine which conditions would decrease water loss in a plant the fastest. Transpiration is the process of water traveling through the plant to allow nutrients in and to cool the plant. The hypothesis tested: If light and heat, humidity, wind, and a controlled environment (where there is no affecting outside force) is applied to a stem then the water pressure will decrease due to transpiration. Pressure will decrease the greatest in light and heat because water will be lost due to evaporation. Pressure will decrease in wind because the pressure on the stem will affect the amount of water being lost. Pressure will decrease in the controlled environment because there will be little change in water levels. Pressure will decrease the least in humidity because water is being added therefore adding more water thus creating more force against the sensor. The data collected from this lab refutes this hypothesis because the results were unexpected.
Hypothesis: The rate of photosynthesis in the water plant hydrilla will change as the rate of carbon dioxide changes.
Not all sugars are made the same. Sugar is naturally found in many foods like fruits, vegetables, and dairy. It is also an added ingredient in many processed foods like soups, condiments, and beverages. The sugars added to foods tend to be highly concentrated and devoid of other nutrients. In contrast, natural sugars are integrated into
In seedless watermelons, rudimentary seed structures form but remain small, soft, white, tasteless and undeveloped tiny seed coats that are eaten virtually undetected along with the flesh of the melon. Seed production for these seedless types is an extremely labor intensive process that makes the seeds relatively expensive. Because germination of these types is often less vigorous than normal types, it is recommended that they be started in peat pots or other transplantable containers. Here the germinating conditions can be closely controlled. Once transplanted, cultivation is similar to that for regular watermelons.
