Photosynthesys and Respiration

• Photosynthesys : Plants take their own food using water, mineral salt, carbon dioxide and sunlight.

• Respiration: Plants take in oxygen and release carbon dioxide.

Photosynthesis1. Roots absorb water and mineral salts (raw sap).

2. Raw sap travels to the leaves through xylem vessels.

3. Stomata take in carbon dioxide, and chlorophyll take sunlight (elaborated sap)

4. Elaborated sap travels to all parts of the plant through phloem vessels.
