Cell Wall

            The cell wall is a rigid structure outside the cell membrane that supports and protects the cell (for plants, fungi, and some protists and bacteria).

The cell wall is made of tough cellulose fibers and other materials made by the cell.

Cell Membrane

       The cell membrane is a structure that forms the outer boundary of the cell and allows only certain materials to move into and out of the cell.

Food, oxygen and water move into the cell through the membrane. Waste products also leave through the membrane.

Golgi Bodies

In cells, structures called Golgi Bodies are stacks of membrane-covered sacs that package and move proteins to the outside of the cell. Golgi bodies are the packaging and secreting organelles of the cell.

Vacuole Membrane

       This is the thin layer that separates the vacuole from the cytoplasm.  This thin membrane allows materials to move in and out of the vacuole.

Vacuole

       Within a cell, a vacuole fills a role similar to a suitcase; as a temporary storage space for the cell.

Vacuoles store water, food, pigments, waste or other materials.

Nucleus

       The largest organelle in the cytoplasm of a eukaryotic cell is usually the nucleus, a structure that directs all the activities of the cell.

The nucleus is like a manager who directs everyday business for a company and passes on information to new cells. The nucleus contains genetic blueprints for the operations of the cell.

Endoplasmic Reticulum

The Endoplasmic Reticulum (ER) is a folded membrane that moves materials around in the cell. The ER extends from the nucleus to the cell membrane and takes up quite a bit of space in some cells.

The ER is like a system of conveyor belts in a business. They act as tunnels in which materials move from one place to another within the cell.

Chloroplast

       Chloroplasts contain a green pigment called chlorophyll. This is what makes plants green.

Chloroplasts take in sunlight, water and carbon dioxide to make oxygen and sugar (a form of food). This process is called photosynthesis.

Cytoplasm

       Cytoplasm is the gel-like material inside the cell membrane and outside the nucleus.

Cytoplasm contains a large amount of water and many chemicals and structures that carry out the life processes in the cell. These structures that the cytoplasm contains are called organelles.
