Short answer questions

 

Q. – Which part of the leaf is involved in the transportation of substance?

The veins present in the leaves helps in the transportation of substance to and from the leaf.

 

Q. – Why do leaves have stomata?

Stomata help plants to take in and out air.

 

Q. – How does chlorophyll help plants in the production of food?

Green plants produce food with the help of chlorophyll found in their leaves, as well as light water and carbon dioxide from the atmosphere.

 

Q. – What is photosynthesis?

Photosynthesis is the process by which leaves convert sunlight, water, and carbon dioxide into food.

 

Q. – What happens to the food prepared by Green Leaves?

The plant’s stem and branches transport prepared food from the leaves to other parts of the plant. The plant uses some of its food in its daily activities.

 

Q. – Where is the extra food produced by the leaves stored?
