Will plants photosynthesize at a constant rate throughtout the day? Why?

Answer 1

I don't think so because photosynthesis uses light as its energy source in the synthesis of carbohydrates from water and carbon dioxide ...and the amount of light falling on any one plant will vary over the hours according to the height of the sun (and thus the slant of the rays falling on the plant) and according to the cloud cover. And also I think photosynthesis would vary also because the plant would respirate and thus lose moisture (water) which rate would depend on the temperature of the air and would thus vary the rate of photosynthesis.

Answer 2

No, it varies according to light levels and other plant stage characteristics.

Basically, most plant do most of their work before 10am in the morning. It seems most plants prefer the lower light of morning than the glare of mid-day.

After the peak, plants sort of take it easy until later in the day when they have another period of activity. This afternoon action is not as great as the morning.

It seems the most efficient plants use only about 11% of the light available. Low, but still the most efficient solar energy converters around.

Answer 3

No, Photosynthesis begins as a reaction to the amount of sunlight received; as the sunlight moves through the electro-magnetic spectrum the photosynthesis rate adjusts.

Answer 4

most likely not. they need light to do it. there are 2 parts to the photosynthesis cycle. I'll spare you the details... but basically a light cycle and a dark cycle. the light cycle occurs in the day. the dark cycle does NOT require light. although... it is a constant process... but I'm not sure by what you mean by constant rate.....
both processes need to be completed for there to be photosynthesis.

Answer 5

No because the intesity of light changes throughout the day.

Answer 6

no. you have different levels of sunlight.
Plus temperature affects the pace of vascular circulation of sap.
