- Plants
- Tissues
- Photosynthesis
- Light energy is absorbed by chlorophyll which is found in chloroplasts
- Epidermal tissues cover the plant
- Tissues
- Mesophyll carries out photosynthesis
- Xylem and Phloem transport substances around plant (found in the vascular bundles)
- Xylem carries water up plant from roots to leaves
- Xylem and Phloem transport substances around plant (found in the vascular bundles)
- Xylem and Phloem transport substances around plant (found in the vascular bundles)
- Phloem carries glucose from leaves to wherever it is needed
- carbon dioxide + water = glucose + oxygen
- Photosynthesis
- Light energy is absorbed by chlorophyll which is found in chloroplasts
- Photosynthesis
- Light energy is used by converting C02 and H20 into sugar (glucose)
- Oxygen is released as a by-product (given off)
- Limiting factors... shortage of light, low temp, shortage of c02.
- Can improve photosynthesis in a greenhouse by improving light intensity, temp, c02
- Glucose produced converts to insoluble starch for storage. Plant cells use it for respiration
