what is an guard sell​

Answer 1

Explanation:

it is cell and sell ok

Guard cells are another type of plant single-cell models to study early signal transduction and stress tolerance mechanisms in plants. Guard cells are surrounded by stomatal pores and are located in leaf epidermis. Guard cells control influx and efflux of CO2 and water from leaves, respectively. Studies showed differential guard cell responses under different abiotic stresses (Irving et al., 1992; Luan, 2002; Chaves et al., 2003; Garcia-Mata et al., 2003; Geiger et al., 2009). Studies on guard cells show better understanding of signaling network in guard cells. Guard cells are very useful single-cell models, which can help to differentiate the role of different genes and proteins in stress signaling networks. Studies based on engineering stomatal guard cell can provide major contribution to develop stress tolerant plants.

Answer 2

Answer:

Guard cells are specialized cells located in the leaf epidermis of plants. ... By changing shape, the guard cells open and close the stoma
