- What part of a plant leaf enables gas exchange and regulates water loss?
- Why is chlorophyll a so efficient?
- What are three ways that water can travel in a plant?
- Mesophyll cells
- Chlorophyll a has alternating single and double bonds.
- There are three ways water travels. The first way is transpiration. This is also known as the
cohesion theory. This is controlled by the stomata. It is the
attraction between molecules of water. The second way water can travel
against the flow of gravity is by root pressure. This occurs when the
stomata is closed, usually at night. Both water and pressure build
up. The third way is capillary action. This is also called
adhesion. It is the ability of water to cling to other things. The
water travels up a very thin tube. The thinner the tube, the higher the
