Question

Which part of the plant gets carbon dioxide from the air for photosynthesis.(i) root hair (ii) stomata (iii) leaf veins (iv) sepals

Answer 1

Dear Student,

◆ Answer - (ii)

Stomata of the plant gets carbon dioxide from the air for photosynthesis.

◆ Extra information about photosynthesis -

• It is a process used by plants and other organisms to convert light energy into chemical energy.
• In photosynthesis plants take CO2 & water, convert it into glucose & O2 in presence of sunlight.

CO2 + H2O + sunlight → C6H12O6 + O2

• Carbon dioxide is obtained through stomata, water absorbed by root hair and sunlight is absorbed by chlorophyll pigment in leaf.

Thanks dear. Hope this helps you..

Answer 2

Stomata are the plant part that gets 'carbon dioxide' from the air for the 'process of photosynthesis.'  

Answer: Option (ii)  

Explanation:  

• Stomata are small openings present on the lower surface of the leaves and even on the sides which are fundamental for the process of photosynthesis.
• They obtain carbon dioxide from the air and along with the sunlight, water and chlorophyll then the process of photosynthesis takes place and glucose and oxygen are created by the leaves.
• Glucose acts as the source of energy and food for the plants and stored and the oxygen is released out through the stomata as well.
