- Stomata are pores in the plant epidermis that are surrounded by two guard cells, which control the opening and closing of the aperture.
- Ion uptake into guard cells causes stomatal opening : The opening of gas exchange pores requires the uptake of potassium ions into guard cells.
- Ion uptake into guard cells causes stomatal opening : The opening of gas exchange pores requires the uptake of potassium ions into guard cells.
- ABA then translocates to the leaves, where it rapidly alters the osmotic potential of stomatal guard cells, causing them to shrink and stomata to close.
- The interior of the broch contains a double cell in the side wall, and a " guard cell " at the foot of the stairs.
- The accumulation of these solutes within the guard cell decreases the solute potential, allowing water to enter the cell and promote aperture of the stomata.
- The pore is bordered by a pair of specialized parenchyma cells known as guard cells that are responsible for regulating the size of the opening.
- The epidermis tissue includes several differentiated cell types; epidermal cells, epidermal hair cells ( trichomes ), cells in the stomatal complex; guard cells and subsidiary cells.
- Malate, as a double anion, often accompanies potassium cations during the uptake of solutes into the guard cells in order to maintain electrical balance in the cell.
- They are produced in pairs with a gap between them that forms a turgid, and closed when water availability is critically low and the guard cells become flaccid.
- The plant epidermis consists of three main cell types : pavement cells, guard cells and their subsidiary cells that surround the stomata and trichomes, otherwise known as leaf hairs.

- Among other things, this technique is used to isolate specific cell types ( e . g ., guard cells from leaves, pericycle cells from roots ) for further investigations, such as transcriptomics.
- Further work with Barry Palevitz showed that microtubules were involved in orienting the cellulose microfibrils in the walls of guard cells in a pattern of radial micellation that is necessary for stomatal function.
- The stomatal pores perforate the epidermis and are surrounded on each side by chloroplast-containing guard cells, and two to four subsidiary cells that lack chloroplasts, forming a specialized cell group known as the stomatal complex.
- There were two small guard cells surrounded by two large similarly shaped subsidiary cells ( paracytic ) deriving from a pronounced elliptical cuticular ledge on the surface of the guard cells surrounding a thickened circumporal area.
- There were two small guard cells surrounded by two large similarly shaped subsidiary cells ( paracytic ) deriving from a pronounced elliptical cuticular ledge on the surface of the guard cells surrounding a thickened circumporal area.
