Palisade leaf cells:

adapted for photsynthesis.

• packed with chloroplasts (for photosynthesis). crammed at top of the cell so nearer light.
• tall shape for big surface area exposed to absorb CO2 from air.
• thin shape means loads can be packed at top of leaf.

Guard cells:

adapted to open and close pores.

• kidney shape, opens and closes the stomata (pores)
• when plant has lots of water, guard cells are filled and go turgid, making the stomata open so gases can be exchanged…
