Plant Cell: Structures and Organelles. To learn more about organelles that can be found in typical plant cells, see: 1  Cell (Plasma) Membrane-a thin, semi-permeable membrane that surrounds the cytoplasm of a cell, enclosing its contents. 2  Cell Wall-outer covering of the cell that protects the plant cell and gives it shape.lant Cell: Structures and Organelles.
