, whether monitoring internal or instead external signals employ receptor proteins, by and large, to detect signals. Receptor proteins may be located at cell surfaces or within the interior of cells. They may detect hormones or instead keep track of what otherwise is going on in cell's environment. whether monitoring internal or instead external signals employ receptor proteins, by and large, to detect signals.

Vacuoles are membrane-bound sacs within the cytoplasm of a cell that function in several different ways. In mature plant cells, vacuoles tend to be very large and are extremely important in providing structural support, as well as serving functions such as storage, waste disposal, protection, and growth.
Vacuoles store food, water, waste for a cell and digestive enzymes then enter the food vacuole which digest the food that was recently taken in by pseudopods.+ 20 others found this useful.acuoles store food, water, waste for a cell and digestive enzymes then enter the food vacuole which digest the food that was recently taken in by pseudopods. + 20 others found this useful.
