Which of the following is NOT needed in order for photosynthesis to take place

Which of the following is NOT a product of photosynthesis

Which of the following is a waste product of respiration

Which of the following does not affect the rate of photosynthesis

The..............cells contain air spaces to allow the movement of gases (i.e. carbon dioxide and oxygen) throughout the leaf.

The...............help to regulate the movement of gases into and out of the leaf. They also help to control the loss of water vapour (transpiration).

The.................cells are packed tightly together near the top of the leaf to collect as much sunlight as possible. They contain many chloroplasts and most photosynthesis takes place in these cells.
