Describe the importance of chlorophyll pigment,stomata and roots in the process of photosynthesis.
Answers
Explanation:
As, we all know that 'chloro' means green and 'phyll 'means leaf.
so, from that u can easily understand that it helps plants in making food ,which phenomenon is known as photosynthesis in
the presence of light and CO2.
stomata help in reducing transpiration and and in some exchange of gases.And also in guttation.
roots help in absorption of water and mineral.
Answer:
Importance of chlorophyll pigment in photosynthesis: "Chlorophyll" absorbs "light energy" from the sun and converts into chemical energy. The light energy trapped is transferred to the "reaction centre of photo systems" by the resonance energy transfer through the electron transport chain. The chemi-osmotic potential is used in various steps of photosynthesis like energy production, reduction of NADP+ to NADPH and reduction of CO2 to glucose.
"Stomata" control the flow of "carbon dioxide, oxygen, and water" to facilitate photosynthesis. During the day, stomata open to absorb "carbon dioxide" from the atmosphere to initiate photosynthesis. Stomata release oxygen out into the atmosphere. "Excess water" is released through stomatal opening and closing during transpiration.
Roots play a role in photosynthesis by absorbing water molecules which is one of the essential elements for photosynthesis along with sunlight and carbon dioxide. Roots also absorb minerals which help to activate the rate of photosynthesis.
