Plants are the higher organisms that are autotrophic return as at, that is, they synthesize their own food materials.
00:13
This synthesis in plants is by the process of photosynthesis.
00:22
This photosynthesis requires sunlight return as sl, carbon dioxide return as co2, and water return as w, the form.
00:34
Carbohydrates with one as sea and the oxygen as bicaram which is released into the atmosphere return as o2 now this carbon dioxide is taken in by the small pores in the leaf which are known as stroma and water is taken in by the roots from the earth or from the sand and the sunlight is taken in from the sun with the help of unlike the help of chlorophyll return as sleepy.
01:11
Now these carbon dioxide enters through the pores but sometimes water also enter into the pores or stroma in the form of water vapor returned as ww but in the regions which are very hot and dry this openings of stroma can also give rise to water evaporation from the plants return as w .e.
01:41
Due to this reason, the plants close their stroma during the day in the places of hot and dry regions.
01:50
Now, photosynthesis, how will photosynthesis occur without carbon dioxide? now, such plants take in carbon dioxide during the night.
02:02
During the night, the stroma are open and carbon dioxide is taken in.
02:07
And the carbon dioxide is stored...
