Let's talk about light energy.
00:05
So light energy is absorbed by chlorophyll.
00:14
Chlorophyll is converted to atp and h positive.
00:28
Okay, so at very low light level.
00:36
Level the plant will be respiring or only not by photosynthesis this is not by photosynthesis next point is that as the light intensity increases the risk rate of photosynthesis will also increases.
01:35
However, the rate will not increase beyond a certain level of light intensity at a a very high light intensities the rate becomes constant so if further light intensity increases the rate of photosynthesis will not going to increase the plant is unable the plant is unable to harvest the light because the chlorophyll system start damaging because of high intensity.
02:55
The chlorophyll system can damage in that case.
03:02
So we will see a curve like this, like this one.
03:09
So here we can on x -axis the light intensity and on y -axis rate of photosynthesis.
03:16
So here, rate of photosynthesis and here it would be light intensity.
03:31
Now let's see what are the bubbles which we can see there.
03:34
From previous thing, what we have seen that when the light intensity is going to increase the rate of photosynthesis.
03:53
Will also increases, okay, continuously but up to a constant level.
04:04
Now when we talk about the bubbles, what are those bubbles basically? those bubbles are representing oxygen...
