The Animal Cell

Aim What are the structures and function of the
animal and plant cells?

1. Cell the basic unit of structure and function
   in all living things.

A. Animal Cell Structures
1. Cell (Plasma) Membrane

1. Separates the cell from its environment
2. Determines what enters and leaves the cell
   (selectively permeable).

3
Fluid Mosaic Model

2. Cytoplasm liquid gel that fills the cell.
Site of all chemical activities and keeps the
organelles from drying out.
3. Nucleus brain of the cell. Contains the
genetic (DNA,RNA) material that instructs the
cell what to do.
4. Ribosome site of protein synthesis. Found
along the Endoplasmic Reticulum and floating
freely in cytoplasm.
5
5. Mitochondria (mitochondrion singular) site
of aerobic respiration (Energy production).
6
6. Endoplasmic Reticulum transport for certain
molecules to go to specific places.
7
7. Golgi Complex makes, packages, and
distributes materials.
8
8. Lysosome - This organelle digests waste
materials and food within the cell. Suicide sac.
9
9. Centrioles involved in cell division. Only
found in animal cells.
10
10. Vacuole Involved in storing foods and
wastes to later be released. Animal cell vacuoles
are smaller than plant cell vacuoles.

II. Plant Cell
12
A. Unique Plant Structures
1. Cell Wall made of cellulose. Non-living.
Gives plant cell its rectangular shape.
2. Large vacuole stores food and wastes.
13
3. Chloroplasts site of photosynthesis.
Contains the molecule chlorophyll which gives
plants its green color.
