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.
Plants need large quantities of water for growth. The most important factor driving water movement in plants is a process known as transpiration. Transpiration is the loss of water from plants in the form of vapor (evaporation).
