Explain the structure of the chloroplast? Draw a neat labelled diagram.

Explain why 12 molecules of water are used as substrate, instead of 6 molecules of water, in the following equation.

6CO₂ + 12H₂0$\stackrel{Light}{\to }$ C₆H₁₂O₂+6H₂0 + 60₂

 A cyclic process is occurring in a C3 plant, which is light dependent and needs O_2. This process does not produce energy rather than it consumes energy.

(a) Can you name the given process?

A cyclic process is occurring in a C₃ plant, which is light dependent and needs O₂. This process does not produce energy rather it consumes energy.

Is it essential for survival?

A cyclic process is occurring in a C₃ plant, which is light dependent and needs O₂. This process does not produce energy rather it consumes energy.

What are the end products of this process?

A cyclic process is occurring in a C3 plant, which is light dependent and needs O2. This process does not produce energy rather it consumes energy.

Where does it occur?

Suppose Euphorbia and Maize are grown in the tropical area. 

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