A Tour of the Cell
CellsTissuesOrgansOrgan SystemsOrganisms

*Cells are made up of smaller functional parts known as cell organelles (little organs). Cell organelles are specialized cell structures that perform specialized jobs in the cell.*

1. Cytoplasm-

*Jelly-like substance inside of the cell
2. Mitochondria-

*In cellular respiration oxygen is used to extract energy from sugars, fats, and other nutrients
3. Cell membrane-

*It is a selectively permeable membrane
4. Nucleus-

*Usually in the center of the cell. Contains the cells genetic information (DNA)
5. Vacuole-

*Plant cells contain a much larger central vacuole
6. Endoplasmic Reticulum-

*Modifies components of the cell membrane and some proteins. Rough ER- Contains ribosomes. Smooth ER- No Ribosomes

7. Ribosome-

*Can be attached to endoplasmic reticulum (ER) or floating free in cytoplasm
8. Lysosome-

9. Golgi complex-

*Proteins from the ER are sent here. The Golgi Complex is in charge of sorting and shipping these proteins to other destinations in the cell.
*Plant Cells: There are two organelles that are found in plant cells but NOT in animal cells
*Plant cells are square in shape and also contain a much larger vacuole*

1. Cell wall-

*Much thicker than plasma membrane
2. Chloroplasts-

*Contains a pigment known as chlorophyl

Cell Transport
I. Objective:

Students will be able to understand what the fluid mosaic model is and explain the process of diffusion.

II. Standards:
4.1.2c The components of the human body, from organ systems to cell organelles, interact to maintain a balanced internal environment. To successfully accomplish this, organisms possess a diversity of control mechanisms that detect deviations and make corrective actions.
4.1.2g Each cell is covered by a membrane that performs a number of important functions for the cell. These include separation from its outside
