English - Curiosity Program - Session - 12| Leaf Disc 2

About the topic: Many of us may have heard that plants make food through photosynthesis. This process requires only a few things: carbon dioxide, water, light, and essential minerals. During this process, trees and plants give off gas (oxygen). But did you know that a very simple experiment can examine the gas (oxygen) released by plants and determine which factors affect photosynthesis? We understood in the last session that trees and plants photosynthesize and release gas in the presence of carbon dioxide, water, light, and chlorophyll.
In this session, we will understand whether there is any effect on the rate of photosynthesis if the amount of carbon dioxide is less or more.
