According to the graph below at which point is the plant performing the least photosynthesis?
For apex--- Point a.
What is the relationship between an increase in light intensity and photosynthetic rate in tomato leaves?
An increase in light intensity typically leads to an increase in the photosynthetic rate in tomato leaves, up to a certain point called the light saturation point. Beyond this point, the photosynthetic rate plateaus as the plant reaches its maximum capacity to utilize light for photosynthesis.
At what point in a plant's life cycle does photosynthesis begin?
Photosynthesis begins in a plant's life cycle during the growth stage, specifically when the plant has developed leaves and is exposed to sunlight.
What happened when you placed Elodea at the light compensation point?
When Elodea is at the light compensation point, the rate of photosynthesis matches the rate of respiration. This means that the amount of oxygen being produced through photosynthesis is equal to the amount being consumed through respiration, resulting in no net change in oxygen levels in the water.
How does changing the light intensity effect photosynthesis and why?
Increasing light intensity generally increases the rate of photosynthesis up to a point where the plant reaches its light saturation level. Beyond this point, further increases in light intensity do not lead to a corresponding increase in photosynthesis. This is because the plant reaches a maximum rate of photosynthesis and becomes limited by factors other than light, such as temperature or carbon dioxide availability.
