Open stomata also provide an opening through which bacteria can invade the interior of the leaf. However, ... Oxygen and carbon dioxide also pass through the cell wall and plasma membrane of the cell by diffusion. The diffusion of carbon dioxide may be aided by aquaporin channels inserted in the plasma membrane.

The following points are made by Colin Brownlee (Current Biology 2003 13:R923): 1) Plant cells are surrounded by cell walls that present an aqueous continuum, the apoplast, through which hormones and other potential regulatory factors can pass [1]. In plants, a function for apoplastic Ca2+ as ... 5) In summary: Stomata,

On an annual basis 300x1015 g of carbon pass through stomata (40% of the carbon in the atmosphere) and 120x1015 g are assimilated as gross primary production (Ciais et al., 1997 ). The pathway of CO2 moving into a plant via stomata is almost universal in vascular land plants, with only few notable exceptions such...
