Which gas is required for photosynthesis

• oxygen

• carbon dioxide

• water

• nitrogen

Photosynthesis uses captured light energy to

• growth

• absorb water

• make glucose

• carry out respiration

A limiting factor

• is when plant cant grow any more

• when there is too much competition

• when there is a lack of a factor which is preventing maximum photosynthesis

• When there is not enough water

If overcome the limiting factor

• there is more photosynthesis so more growth

• there is more photosynthesis so less growth

• there is less photosynthesis so less growth

• there is less photosynthesis so more growth

Select all of the limiting factors of photosynthesis

• oxygen levels

• water levels

• Carbon dioxide levels

• temperature

Select all of the limiting factors of photosynthesis

• Sunlight

• Water levels

• Carbon dioxide levels

• Light intensity
