Question

Explain with an activity that carbon dioxide and water are necessary for photosynthesis in detail
​

Answer 1

Explanation:

proving proving that carbon dioxide is important for photosynthesis we can perform the following activity

pick two plants of same size and nearly if possible of same variety no place both plant on on glass plate and name them as a and b not take some potassium hydroxide on a petridis and keep it aside on the plant named as a not cover Buddha plants by using a cover and also make sure that this setup is their diet which means no air is going inside or not the inside there is coming outside not leave the similar set up for a 72 2 hours and then observe that the plant it which was kept along with potassium hydroxide will not show any change in colour when iodine test is done but man we do on iodine test using leaves of the plant measures get without potassium hydroxide will also change in colour so by this activity we can do draw that carbon dioxide is very important for photosynthesis because the potassium hydroxide which we have used in this activity is generally used for absorbing carbon dioxide and because it was present along but the plant so it will absorb all the carbon drafter present in that it up and hence the plant doesn't show any change in colour when it was tested using iodine solution

Answer 2

Answer:

The leaf from the plant (which was inside the other bell jar without potassium hydroxide and so heaving carbon dioxide in it ) turns blue black on adding iodine solutions showing that starch is present in the leaf .... SO this shows that carbon dioxide is necessary for the process of photosynthesis to take place
