Hii Buddy.....!!!
Your answer is here -:
Take two potted plants of the same kind. Keep one in the dark (or in a black box) for 72 hours and the other in sunlight. perform iodine test with the leaves of both the plants as you did in class VI. Record your results. Now, leave the pot which was earlier kept in the dark in the sunlight for 3-4 days and perform the iodine test again on its leaves record your observations in your notebook the leaves other than green also have chlorophyll the large amount of red, Brown and other pigments masks the green colour photosynthesis takes place in this leaves also
Carbohydrates are made of carbon, hydrogen and oxygen these are used to synthesis other components of food such as proteins and fats but proteins are nitrogenous. Substances which contain nitrogen. From where do the plants obtain nitrogen recall that nitrogen is present in abundance in gaseous form in the air however plants can not absorb nitrogen in this form so I have certain bacteria that convert gaseous nitrogen into a usable form and release it into the soil these are absorbed by the plants along with water also you might have seen farmers adding fertilizers rich in nitrogen to the soil. In this way, the plants fulfill the requirements of Nitrogen along with their other constituents. Plants can then synthesise proteins and vitamins.
Thank You....!
