Palisade leaf cells - are adapted for PHOTOSYNTHESIS, most of the cells are crammed at the top of the leaf so they are nearer the light. Also the tall thin shapes means that alot of surface area is exposed down the side for absorbing CO2.
Guard cells - are adapted for OPENING AND CLOSING THE STOMATA, when the plant has lots of water it opens the stomata to allow gases to exchange for photosynthis. So when there is a lack of water the stomata closes so that water vapour doesnt escape.
Red blood cells - are adapted for CARRYING OXYGEN, they have a big surface area for absorbing oxygen and so that they can go through the capilliraries easily. They contain loads of haemoglobin and dont contain a nucleus.
Root hair cells - are adapted for ENABLING THE PLANTS TO TAKE IN THE WATER THEY NEED, the root hairs increase the surface area for water to move into the cell. They are also normally placed near the xylem tissue that carries water to the rest of the plant.
