FC: Cells

1: The cell is the basic unit of life. In other words, the building blocks of life. | All living organisms are composed of cells. They may be unicellular or multicellular. | Cells arise from pre-existing cells.

2: Robert Hooke- Hooke saw little pockets in a thin slice of cork and called them cells. | Schwann- Schwann declared that all animals have cells. | SCIENTISTS

3: MAKING THEORIES | Virchow- Virchow determined that all cells came from previous cells. | Schleiden- Schleiden declared that all plants have cells.

4: Prokaryotic cells- Have no nucleus. Simple celled organisms. Examples include fungi and bacteria.

5: { | Prokaryotic vs. Eukaryotic | Eukaryotic cells- Have a nucleus. Very complex. Humans and plants are examples.

6: Plant Cells- Rectangular in shape. Contain chloroplasts to make food. One very large vacuole. Contains cell wall and cell membrane. Lysosomes usually are not evident. | Plant vs. Animal Cells

7: Animal Cells- Have a round shape. Do not contain any chloroplasts. Contains one or more small vacuoles. Contains centrioles. Contains only a cell membrane. Lysosomes are present in cytoplasm.

8: The nucleus is the "brains" of the operation. It contains the DNA and tells the rest of the cell what to do. | The cell membrane is what protects the cell from the outside world. It controls what goes in and out of the cell. | Cytoplasm is a jelly-like substance that holds all the other organelles in the cell. | The nucleolus is in the center of the nucleus and partially creates ribosomes. | The job of the golgi apparatus is to modify, sort, and package macromolecules.

9: Ribosomes create proteins | The rough endoplasmic reticulum facilitates protein folding and the transport of proteins. | Contain hydrolytic enzymes for digestion. | Mitochondria produce APT. Then APT is turned into energy by another organelle. | The smooth endoplasmic reticulum creates lipids (fats) and regulates calcium concentration.

10: The cell membrane protects the cell from the outside environment. It also controls the movement of substances in and out of cells.

11: Homeostasis- The tendency toward a relatively stable equilibrium between interdependent elements, esp. as maintained by physiological processes. | Homeostasis | Homeostasis is when the factors of the body/cell are balanced. For example, when your body heats up you start to sweat to maintain your body temperature and homeostasis.
