Leaf Structure and Photosynthesis

The cell organelle where photosynthesis occurs in plant cells is the

• chloroplast

• mitochondrion

• vacuole

• nucleus

Photosynthesis occurs mostly in this part of the leaf because the cells have so many chloroplasts:

• upper epidermis

• cuticle

• palisade mesophyll

• spongy mesophyll

The reactants needed for photosynthesis to occur are:

• carbon dioxide & water

• carbon dioxide & oxygen

• oxygen & water

• carbon dioxide, oxygen & water

The role of the guard cell is to

• help control the temperature of the plant

• control how much water enters the leaf

• control how much glucose is stored

• control the movement of water vapour & gases

• Xylem cells

• Waxy cuticle

A plant species lives in an area with limited sunlight. Which physiological adaptation would be most useful to the plant? 

• colorful flowers

• large leaves

• deep roots

• thin cuticle

The water needed for photosynthesis comes into the leaves through the

• upper epidermis

• stomata

• guard cells

• xylem cells

Sugar and the products of photosynthesis move through the plant in 

• the phloem cells

• the xylem cells

• the root hair cells

• palisade mesophyll layer
