- How are leaves adapted for photosynthesis
- They are thin.
- This provides a short diffusion pathway for carbon dioxide to diffuse to the mesophyll and palisade cells.
- They have a transparent epidermis.
- This allows light to easily pass through.
- They contain chlorophyll and other pigments.
- These absorb energy from different parts of the spectrum.
- They have lots of stomata (pores in the lower epidermis).
- These allow carbon dioxide in and oxygen out. Guard cells control whether they are open or closed.
- They have tightly packed cells in the upper palisade layer.
- This means more of these cells can fit in along the layer.
- They are broad and flat in shape.
- This gives a large surface area, to absorb as much light as possible.
- Their veins contain vascular bundles.
- These form a network that supports the leaf blade. They also carry water from the root to the leaf, and carry soluble sugars away.
- There are air spaces inside of the leaf.
- This gives a large surface area to volume ratios, which allows maximum absorption of gases.
- There are air spaces within the spongy mesophyll layer.
- This allows carbon dioxide to diffuse from the stomata to the palisade cells.
- The upper palisade layer contains the most chloroplasts.
- Because this layer receives the most light.
- They are thin.
