What are the small openings on an underside of a leaf through which gas is exchanged?

• stem

• stomata

• chlorophyll

• chloroplasts

Answer explanation

Stomata are the small openings on the underside of a leaf through which gas is exchanged, making it the correct choice.

Where does cellular respiration take place?

• chloroplasts

• stomata

• mitochondria (in cytoplasm)

Answer explanation

In photosynthesis, what are the reactants (the input, what the plant takes in)?

• water

• oxygen

• glucose

• carbon dioxide

• milk

Answer explanation

In photosynthesis, the reactants are water and carbon dioxide. These are the inputs that the plant takes in to produce glucose and oxygen.
