                        Cell Parts and Their Functions

Nucleus - Controls the cell.
Nucleolus - Makes ribosomes, maybe more than one in a cell, found in
                the nucleus.
Chromosomes- Determines what traits a living thing will have,
                passes information from parent to offspring.
Cell Membrane - Gives the cell shape, holds the cytoplasm, and
                controls what moves into and out of the cell.
Cytoplasm - Jellylike material (cytosol and organelles), most of the
                cell's chemical reactions take place there, and made
                up of mostly water and some chemicals.
Vacuoles - Liquid-filled, may store food, water, minerals, or wastes.
                In plants it takes up a lot of space. There maybe
                more than one.
Mitochondria - Produce energy when food is broken down, often
                called the "powerhouse of the cell".
Ribosomes - Where proteins are made, and often connected to the
                endoplasmic reticulum. A cell may have as many as
                500,000.
Endoplasmic Reticulum - The "transportation system" in the cell,
                connects the nuclear membrane with the cell
                membrane. Used in detoxification of the cell. "ER"
Centrioles - Found only in animal cells, is used in cell reproduction to
                help the chromosomes arrange before cell division.
Cell Wall - Found only in plant cells. Forms a thick outer covering
                outside the cell membrane, gives the plant support
                and shape.
Chloroplasts - Found only in plant cells. Found in the cytoplasm of green plant
                cells, contain chlorophyll, traps the energy from light, and is
                where photosynthesis takes place.
Lysosomes - digests food particles with enzymes, pinched of pieces
                of golgi apparatus
Golgi apparatus (bodies)- flat stacks, packages and secretes from
                cell.
