Hey Timmy do you want to go to my house and ride around in my gokart. ya that sounds like fun. Timmy do you think the parts of the cart can relate to cells because we are talking about cells at school. Why yes we could because the motor or engine in a go kart is a lot like the mitochondria. Because the mitochondria is like the motor because they both are the power house. Which they keep the cart or cell active or running. Wow Timmy you know a lot about cells already. Ok know test me. How can the brake relate to a cell. The brake and gas pedal direct the activity and speed. so when you push the brake you stop. This is a lot like the chromosomes because they direct the activity of the cell just like the gas and brake pedals. NICE Timmy. …show more content…
nice try there Timmy. ribosomes are like a spark plug because the ribosomes produce, and the spark plug produces enlightened gas for the cart engine. Just like the ribosomes produce things for the cell. Ok Blake what do you think is the most important part of the cart.The gas filter. Ok then how can that relate to a cell. That's easy the cell membrane Let's nutrients and waste in and out of the cell. This sounds a lot like a filter a gas filter to be exact. Cause the gas you put in may be a little dirty so the gas filter filters out all of the bad things just like the cell membrane lets good things in and bad things
The ATP is used for many cell functions including transport work moving substances across cell membranes. It is also used for mechanical work, supplying the energy needed for muscle contraction. It supplies energy not only to heart muscle (for blood circulation) and skeletal muscle (such as for gross body movement), but also to the chromosomes and flagella to enable them to carry out their many functions. A major role of ATP is in chemical work, supplying the needed energy to synthesize the multi-thousands of types of macromolecules that the cell needs to exist. ATP is also used as an on-off switch both to control chemical reactions and to send messages.
The building of the grocery store is like the cell membrane, because it gives it structure and keeps everything inside safe. The security guard of the front door in the grocery store is like the cell membrane, because it says what can come in and out of the cell. The boss of the store is like the nucleus, because they tell the employes what to do and what needs to be done. The floors of the grocery store is like the cytoplasm, because it hold everything in it place, where it need to be. The illes in the store is
In “Life of a Cell,” the author uses rhetoric and figurtic language to reassure peoples fear of disease and to assure them the bodies system is fully capable to attacking anything that would be an issue or illness to itself. He writes about the fear of germs and bacteria; the ineveitibility of germs attacking a cell system. He writes about the many preventions and precautions others take to avoid diseases which metaphorically they “come after them for profit.” Thomas writes this in less scienfitic terms that an average person could comprehend and be assured that their fears are irritaonal to an extent. By using metaphors, similes, personification, and imagery, the reader is reassured that the human body is fully capable of handling diseases.
The cell membrane is a structure that controls what enters and leaves the cell. In a basketball stadium, the security guards are like the cell membrane. They can say who comes in if they don’t cause any problems and are following the rules and they can reject them and make them leave if they have something they aren’t supposed to or they are doing something wrong. This is how security guards are like a plant cell’s cell membrane because the security guards control what enters and leaves the stadium like the membrane controls what enters and leaves the cell.
The Lives of a Cell: Notes of a Biology Watcher by Lewis Thomas consists of short, insightful essays that offer the reader a different perspective on the world and on ourselves.
A)Is incorrect because all cells require ribosomes (Module 14, slide 4) . Ribosomes are important since they make proteins which are part of the basic building blocks of life (Campbell 102).
Eukaryotic cells have their chromosomes contained in a nucleus. Unicellular orgasisms such as amoebas and yeast, or multi-cellular organisms such as plants and animals consist of eukaryotic cells. Human being consist of approximately 1 billion cells per gram tissue. DNA located in 23 pairs of chromosomes is contained in each cell nucleus. Schleiden in 1838 and Schwann in 1839 made very important discoveries that we consist of cells, and Remark discovered that cells prolifarate through division in 1850. Three decades ago, the molecular mechanisms that regulate the cell cycle and thus cell division was able to be identified. It has been known that these vital mechanisms are conserved through evolution and function in the same way in eukaryotic organisms.
...a continuous flow of ATP. In order to support a constant flow of ATP, the mitochondria are concentrated at synapses. If these changes in the organelle functions continue in an altered state, there is a greater risk of affecting the synaptic plasticity. In addition, the “paucity of mitochondria causes the synaptic dysfunction in dendrites and axons” (2). Therefore, synaptic mitochondrial dysfunction is indicative of Alzheimer’s pathogenesis (2).

The mitochondria produces food for the cell by converting energy the cell needs. The mitochondria and the nucleus are two organelles within a cell that have many of the same similarities. Both organelles are made of two membranes. These layers isolate within the organelle all things considered, yet have protein channels that permit things to go in and out. Both contain DNA material that conveys qualities that encode for proteins. Both have qualities that make ribosomes, the machines that read the guidelines in RNA to make
The mitochondria is an organelle which is generally an oval shape and is found inside the cytoplasm and is again apart of the eukaryotic cells. The main function of the mitochondria is to complete cellular respiration; in simple terms it acts like a digestive system to break down essential nutrients and to convert it into energy. This energy is usually found to in ATP which is a rich molecule taken from the energy stored in food. Furthermore, mitochondria stores calcium for signalling activities; such as heat, growth and death. They have two unique membranes and mitochondria isn’t found in human cells like the red blood cells yet liver and muscle cells are filled entirely with mitochondria.
Cells are the basic building blocks of all living things. The human body is composed of trillions of cells. They provide structure for the body, take in nutrients from food, convert those nutrients into energy, and carry out specialized functions. But it also contains highly organized physical structures which are called intracellular organelles. These organelles are important for cellular function. For instance Mitochondria is the one of most important organelle of the cell. Without Mitochondria more than 95% of the cell’s energy, which release from nutrients would cease immediately [Guyton et al. 2007].
The cell I chose was a “Motor Neuron”. I learned many facts about this cell. This cell has many organelles , functions , and has reasons for its structure.
The Cell, the fundamental structural unit of all living organisms. Some cells are complete organisms, such as the unicellular bacteria and protozoa, others, such as nerve, liver, and muscle cells, are specialized components of multicellular organisms. In another words, without cells we wouldn’t be able to live or function correctly. There are Animal Cells and Plant Cells. In Biology class the other day we studied the Animal Cell. We were split into groups of our own and we each picked a different animal cell slide to observe. My group chose the slide,'; Smeared Frog Blood ';.
The cell theory was not just created by one scientist at one point in time. The cell theory was discovered over the course over hundreds of years, by many scientists, some of whom have never been recorded. The three principles of the cell theory that are used today are:
