In many animal tissues (e.g., connective tissue), each cell is separated from the next by an extracellular coating or matrix.
However, in some tissues (e.g., epithelia), the plasma membranes of adjacent cells are pressed together. Four kinds of junctions occur in vertebrates:
In many plant tissues, it turns out that the plasma membrane of each cell is continuous with that of the adjacent cells. The

The Plant Cell
Plant cells are eukaryotic and have many of the structures found in animal cells. Link to pages describing these.
