Photosynthesis

Recall what chemical is produced by photosynthesis to provide food for plants.

• Glucose

• Oxygen

• Carbon dioxide

• Sucrose

Recall where plants should be kept to allow photosynthesis to occur.

• A dark cupboard

• A sunny, airy place

• The vacuum of space

• A petrol tank

Recall the correct chemical to complete the photosynthesis equation below:

Carbon dioxide + water → Glucose + _______

Select the correct words to fill in the blanks below:

Chlorophyll is an essential part of the ______ reaction.

It takes in sunlight and converts it into chemical _______, this helps the reaction to happen.

Chlorophyll is also the reason why leaves are _______.

• Photosynthesis

• Respiration

• Green

• Nutrients

• Energy

Recall what are the products of the light-dependent reaction in photosynthesis.

• ADP, NADP, H+ & oxygen

• ATP, NADPH, H+ & carbon dioxide

• ATP, NADPH, H+ & oxygen

• ADP, NADP, H+ & carbon dioxide

Recall which of the following apply to the light-dependent reactions of photosynthesis.

Select ALL correct options

• Carbon dioxide is required for the light-dependent reactions

• Light is required for the light dependent reactions

• ATP is produced during the light-dependent reactions

• NADPH and oxygen are the products of the light-dependent reactions which enter the light independent reactions

Select the correct words to fill in the blanks below:

____ is not needed for the light-independent reaction to occur; this reaction takes place in the stroma of chloroplasts.

The light-independent reaction involves H+ from _______ and carbon dioxide to form glucose.

______ from the light-dependent reaction is required to drive this reaction.

• Light

• Water

• NADPH

• ATP

• ADP

Recall which of the following correctly outlines the main steps in photosynthesis.

• Light joins carbon dioxide to an acceptor compound which is then reduced by hydrogen

• Light splits water and the resulting product combines with a compound that has incorporated carbon dioxide

• Light splits carbon dioxide and the resulting carbon then combines with oxygen and hydrogen obtained from water

• Carbon dioxide combines with hydrogen which has been split from water by light

Recall where the light-dependent stage of photosynthesis occurs.

• Stroma

• Cytoplasm

• Inner membrane

• Thylakoids

Recall where the light-independent stage of photosynthesis occurs.

• Stroma

• Cytoplasm

• Inner membrane

• Thylakoids
