- Structural features of a leaf
- Leaf
- Large Surface area
- Capture as much light as possible
- Thin
- Light penetrates through the leaf
- Stomatal Pores
- Allows Carbon Dioxide to diffuse into the leaf
- Air Spaces in spongy mesophyll
- Allow Carbon Dioxide to diffuse into the photosynthetic cells
- Spaces between palisade cells
- Allows Carbon Dioxide to diffuse to the photosynthetic cells
- Large Surface area
- Cells
- Cuticle and epidermis are transparent, cellulose walls are thin
- Light penetrates through to the mesophyll
- Palisade cells have a large vacuole
- Chloroplasts form a single layer at the periphery of each cell as to not shade each other
- Palisade cells are cylindrical, elongated at right angles to the surface of the leaf
- Leaves can hold more palisade cells, light only has to pass through two epidermal cell walls and one palisade cell wall before reaching the chloroplasts
- If they were stacked horizontally, light would be absorbed by passing through too many cell walls preventing it reaching the chloroplasts
- Palisade cells are cylindrical, elongated at right angles to the surface of the leaf
- Leaves can hold more palisade cells, light only has to pass through two epidermal cell walls and one palisade cell wall before reaching the chloroplasts

- Leaves can hold more palisade cells, light only has to pass through two epidermal cell walls and one palisade cell wall before reaching the chloroplasts
- Cuticle and epidermis are transparent, cellulose walls are thin
- Chloroplasts
- Large surface area
- Maximum absorption of light
- Move within palisade cells
- Chloroplasts move to the top of the cells on bright days and move to the bottom on bright days
- Maximises light absorption and protects from bleaching
- Move within palisade cells
- Chloroplasts move to the top of the cells on bright days and move to the bottom on bright days
- Maximises light absorption and protects from bleaching
- Maximises light absorption and protects from bleaching
- Chloroplasts move to the top of the cells on bright days and move to the bottom on bright days
- Move within palisade cells
- Maximises light absorption and protects from bleaching
- Chloroplasts move to the top of the cells on bright days and move to the bottom on bright days
- Rotate within palisade cells
- Thylakoids maximise the absorption of light
- Pigments in the thylakoid are in a single layer at the surface of the membrane
- Pigments maximise their absorption of light
- 5 times as many chloroplasts in palisade cells than in spongy mesophyll
- Palisade cells are at the top of the leaf and are exposed to me light than the spongy mesophyll
- Chloroplasts are exposed to as much light as possible
- 5 times as many chloroplasts in palisade cells than in spongy mesophyll
- Palisade cells are at the top of the leaf and are exposed to me light than the spongy mesophyll
