How Does Water Temperature Affect Photosynthesis

Water temperature changes will not produce an effect on photosynthetic properties of freshwater algae. Temperature affects photosynthesis by allowing the algae or aquatic vegetation to photosynthesize and respire when there is an optimum room temperature. As water temperature rises, the rate of photosynthesis increases, providing there are adequate amounts of nutrients, but if water temperature plummets and there is a lack of sufficient amounts of nutrients, then the rate of photosynthesis will decrease.

It has been claimed that the changes in water temperature will have no effect on photosynthetic rates in algae or aquatic vegetation.

In this lab, 200 mL of algae/plant material was mixed with 500 mL of water at 22 °C in a biochamber. Attached to the biochamber was an O2 probe connected to a LabQuest that was attached through a USB port on a computer that was running the program Logger Pro. The temperature of the mixed contents in the biochamber was taken in ten minute intervals for thirty minutes. After all needed data was recorded in a notebook, including the △Y, and the lab was complete, the area used for the lab was cleaned and everything was

Aquatic animals and plants that are living in algae or aquatic vegetation add carbon dioxide into their aquatic habitat during respiration and they also use up the oxygen particles during respiration, including those that are involved in decay. The temperature of the water does not place an effect on the rate of photosynthetic rates in algae or aquatic vegetation because photosynthesis will either add oxygen to the water, or photosynthesis will use up the carbon dioxide in the water. This information is known because the oxygen levels on the computer program Logger Pro either stayed the same percentage or fluctuated between 52% and 53% during the time of the
