c. Which enzyme is there in bundle sheath cells and mesophyll cells?

Tomatoes, carrots and chillies are red in colour due to the presence of one pigment. Name the pigment. Is it a photosynthetic pigment?

Why do we believe chloroplast and mitochondria to be semi-autonomous organelle?

A cyclic process is occurring in C3 plant, which is light dependent, and needs O₂. This process doesn’t produce energy rather it consumes energy.

a. Can you name the given process?

b. Is it essential for survival?

c. What are the end products of this process?

d. Where does it occur?

Suppose Euphorbia and Maize are grown in the tropical area.

a. Which one of them do you think will be able to survive under such conditions?

b. Which one of them is more efficient in terms of photosynthetic activity?

c. What difference do you think are there in their leaf anatomy?
