Many of the structures and functions we have discussed about eukaryotic animal cells are also found in plant cells, but there are some additional structures found in plant cells that are not found in animal cells.
All plant cells have in addition to a plasma membrane , a cell wall.
This is very important for maintaining cell structure, and function. A young plant secretes a thin layer of this substance outside its plasma membrane. See page 125 of your text for diagram. Between the primary walls of cells, separating the cells is a substance called pectin , which makes up a layer called the middle lamella. A large vacuole in the center of mature plant cells.
