Plants and Photosynthesis
- Photosynthesis
- Plants make food in their leaves by photosynthesis.
- The raw materials for photosynthesis are carbon dioxide and water.
- The light energy needed for photosynthesis is trapped by chlorophyll.
- Chlorophyll is found in chloroplasts in green parts of leaves.
- Plants make food in their leaves by photosynthesis.
- Biomass
- A plant's biomass is the matter that is made of.
- A plant's biomass is the matter that is made of.
- Respiration
- Glucose from photosynthesis is used to make starch, to release energy during respiration and to make new materials.
- Roots are branched and have root hairs to increase their surface area. They need oxygen to respire.
- Plants use their roots to take up water and minerals such as nitrates.
- Plant need nitrates to make proteins for making and respiring cells.
- A plant uses water to cool its leaves, to swell up fruits, to make its cells firm and to stretch its cell growth.
- Glucose from photosynthesis is used to make starch, to release energy during respiration and to make new materials.
- Oxygen and Carbon Dioxide
- Most photosynthesis happens in the cells near the to of the leaf.
- About 21% of the air today is oxygen and about 0.03% is carbon dioxide.
- Plants in oceans and forests help to maintain the balance of oxygen and carbon dioxide in the atmosphere.
- Respiration, rotting and burning release carbon dioxide.
- Most photosynthesis happens in the cells near the to of the leaf.
