YEAR 4 SCIENCE - PHOTOSYNTHESIS

What gas do plants need in order to perform photosynthesis?

• oxygen

• carbon dioxide

• nitrogen

• hydrogen

Why do plants need sunlight for photosynthesis?

• The light creates heat needed for photosynthesis to occur

• The light provides the energy needed to power photosynthesis

• Plants can't absorb carbon dioxide in darkness

• Plants can't absorb water in darkness

What gas do plants give off as a result of photosynthesis?

• oxygen

• carbon dioxide

• nitrogen

• hydrogen

The green substances in leaves that absorbs energy from the sun

• Carbon Dioxide

• Chlorphyll

• Water

• Energy

A gas absobed by plants for the process of photosynthesis.

• Carbon dioxide

• oxygen

• nitrogen

• Chlorophyll

A part of the plant that grows in and absorbs water from the soil.

• Leaves

• Fruits

• Roots

• Flowers
