Photosynthesis and Leaf Structure Review

What structure within a plant cell does photosynthesis?

• Sap vacuole

• Cytoplasm

• Chloroplasts

• Chlorophyll

Most of the chloroplast cells are found in the

• upper epidermis

• pallisade mesophyll layer

• lower epidermis

• stomata

Tags

The important gases, carbon dioxide and oxygen, enter and leave the leaf through the

• upper epidermis

• phloem

• stomata

• guard cells

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 

Which of the following is the correct equation for PHOTOSYNTHESIS?

• CO₂ + light + H₂O --> O₂ + Sugar

• CO₂ + sugar + H₂O --> O₂ + light

• _O2 + light + H₂O --> CO₂ + Sugar

• CO₂ + O₂ + H₂O --> Light+ Sugar

What two things are the product (end result) of photosynthesis?

• chloroplast

• glucose

• oxygen

• carbon dioxide

Tags

NGSS.MS-LS1-6

The leaf has a shiny, waxy cuticle around it to

• increase the rate of photosynthesis

• attract more light

• control water loss

• stop carbon dioxide and oxygen gases escaping

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
