One type of it is stem cells. Queiscent cells are adult cells which do not divide, but under certain stimulation when it is needed, it can undergo cell division. One example are hepatocytes (liver cells).Permanent cells are cells that do not divide at all and have no such capabilities.ne type of it is stem cells. Queiscent cells are adult cells which do not divide, but under certain stimulation when it is needed, it can undergo cell division. One example are hepatocytes (liver cells).
Hairs trap a still layer of air to slow the rate of water vapor loss. Epidermal tissue has stomatal guard cells that regulate transpiration. Vascular tissue has a role in internal transport of water from root to leaf. The xylem is lignified to control water dispersal from the column. Limiting water exit to the plasmodesmata (desmodesmata) channels through cell walls.
A second structure important to all plant cells is the central vacuole, which is a large storage compartment in plant cells. Both the cell wall and the central vacuole help plant cells regulate water movement, or osmosis, to keep plant cells strong enough to withstand a few days without water. wilting plant! Notice, however, that even in a hypertonic environment, the cell wall helps maintain the shape of the plant cell. As soon as you started watering the plant regularly, the plants were again in an isotonic, or equal, water environment.
