| Term | Definition |
|---|---|
| Nucleus | Contains the genetic material (DNA) for the cell |
| Cytoplasm | The fluid that fills up most of the space in the cell. |
| Mitochondria | Provides energy for the cell. The power plant of the cell. |
| Vacuole | Stores materials for the cell. Helps regulate turgor pressure in the plant cell |
| Ribosomes | Creates proteins for the cell |
| Endoplasmic Reticulum (Smooth) | In eukaryotic cells, breaks down lipids/steriods, controls calcium release, made of lipids |
| Chloroplast | Converts energy from the sun, water (H2O), and carbon dioxide into food (sugar and oxygen) for the cell. Located in only the plant cell. Also responsible for the plant's green color (chlorophyl). |
| Cell Wall | Provides protection and structure for the cell. Located in only the plant cell |
| Cell Membrane | Thin, flexible outer layer that holds the cell together and controls what enters and leaves the cell |
| Unicellular | Made up of one cell |
| Multicellular | Made up of more than one cell |
| Prokaryote | Cells with no nucleus or membrane-bound organelles |
| Eukaryote | Cells with a nucleus and membrane-bound organelles |
| Cell Theory | All living things are made of cells, cells can only come from other living cells, cells are the basic building block of life. |
| Organelle | Structures that carry out funtions in a cell |
| Nucleolus | Located inside the nucleus. Produces ribosomes |
| Rough ER | Transpots proteins throught the cell |
| Golgi Body | Packages macromolecules and proteins for the cell in vesicles. Makes lysosomes, stack membrane bound vesicles |
| Lysosome | Breaks down old/uneeded parts of the cell with enzymes |
| Turgor Pressure | Pressure exerted on a plant cell wall by water passing into the cell |
| Endocrine System | Secretes hormones that regulate body funtions. Coordinates other body systems. Major organs include: Endocrine Glands- pituitary, hypothalamus, pineal, thymus, thyroid, parathyroid, adrenals, pancreatic islets, testes (males), ovaries (females) |
| Immune System | Protects body against diseases Major organs include: Lymph nodes, lymphatic vessels, tonsils, spleen |
| Lymphatic System | Assists in recovering the body's tissue fluids and returning them to the heart. Major organs include: Lymph nodes, lymphatic vessels |
| Homozygous | Having identical (same) alleles |
| Heterozygous | Having different alleles |
