The spongy mesophyll cells in the leaf are separated by many air spaces. How does this aid key biological processes in the plant?

A) It allows easy diffusion of gases for respiration and photosynthesis.

B) It allows substances like water and minerals to be transported around the leaf to be used in respiration and photosynthesis.

C) It allows sunlight to penetrate down to palisade layer to increase rate of photosynthesis.

D) It increases the size of the leaf, which allows the maximum amount of sunlight to be captured for photosynthesis.

A) The membrane will have large gaps for molecules to pass through.

B) The membrane can only be permeated by large molecules.

C) The membrane will only allow certain substances to move in or out of the cell.

What is the primary role of the stroma in the chloroplast?

A) To provide the site for the light-independent stage of photosynthesis

B) To provide the site for the light-dependent stage of photosynthesis

C) To connect, and allow communication between, the thylakoids

D) To provide a membrane to which photosynthetic pigments can attach

Meristem cells are found in the tips of plant roots and shoots. Which of the following best describes meristem cells?

A) Meristem cells slowly divide and replace some cells in the plant.

B) Meristem cells can rapidly divide and specialize into all types of plant cell.

C) Meristem cells are specialized in carrying out photosynthesis.
