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 lose gallons of water every day through the process of transpiration, the evaporation of water from plants primarily through pores in their leaves. Up to 99% of the water absorbed by roots is lost via transpiration through plant leaves.
