In order to transport materials around a plant there is xylem tissue, which transports , and tissue, which transports dissolved nutrients. These tissues can all be arranged into plant , such as a leaf.
In the leaves, water vapour gathers in spongy spaces but is normally trapped in the leaf by closed . These open by the action of guard cells, and the water vapour is released from the leaf. The term describes the movement of water out of the leaves of plants. An experiment can be used to estimate the rate of this process, whereby the speed of a bubble along a attached to a plant can be recorded. This process differs from the movement of sugars, which takes place by a process known as .
Plants can respond to light or to gravity using the plant hormone , which causes unequal growth rates in roots and shoots. The hormone is important in plant cell division, and is commonly used to control ripening.
