Answer: Helps the plant breathe: The epidermis of the leaf contains guard cells that control and regulate the small pores on the undersurface of the leaves. These pores are called stomata. Stomata are responsible for regulating water in and out of the cell. It is also responsible for the exchange of gases across the epidermis.
The correct answer is: Induction, because this could be easily changed by changing the cell's environment.
Cell differentiation (process by which cell becomes specialized) can be under the influence of many factors:
• Cytoplasmic influence because cytoplasm can influence and control the behaviour of nuclear genes.
• Embryonic induction-changing the cell environment
For example: if cells from one region of the embryo are transplanted to some other region that transplant will most likely differentiate according to the chemical regulators of the surrounding cells.
• Proteins present in a cell influences its differentiation
• Cell-Cell interactions via cell-cell adhesion and signalling molecules.
