Most of the water that enters a plant will exit the leaf into the atmosphere. This provides a continuous stream of water which is known as the transpiration stream. Surface area (not an ...

The cell wall is totally permeable and has no role in controlling what enters and leaves a cell. It is a rigid structure that provides a plant cell with support and keeps non-woody plants upright.

Here we describe the pathways and mechanisms driving water uptake and transport through plants, and causes of flow disruption. Water is the most limiting abiotic (non-living) factor to plant ...

The thylakoids contain the light-harvesting complex, including pigments such as chlorophyll, as well as the electron transport chains used in photosynthesis (Figure 2). Plant cell walls are ...
