Cell Organelles
| Term | Definition |
|---|---|
| Nucleus | Control center of the cell; it houses chromosomes/DNA-the genetic code |
| Cytoplasm | Gel-like liquid that fills the cell; gives structure and suspends organelles |
| Mitochondria | Powerhouse of the cell; it releases energy for the cell (mitochondria = plural) |
| Vacuole | Stores water (in plant cells it is much larger than animal cells) |
| Ribosomes | Protien synthesizers or protien builders |
| Rough Endoplasmic Reticulum | Contain ribosomes the surface, protien synthesized in the ribosomes collect in the endoplasmic reticulum for transport thoughout the cell |
| Chloroplast | Plant cell's food factory conatining chlorophyll; the site of photosynthesis |
| Cell Membrane | Surrounds the cyptoplasm of plant and animal cells (allows certain things to pass into the cell and allows certain things to pass out of the cell) |
| Unicellular | Organisms that have only one cell |
| Multicellular | Organisms who have many cells |
| Prokaryote | Organisms whose cells lack a nucleus and membrane-bound organelles |
| Eukaryote | Organisms whose cells have a distinct nucleus and organelles |
| Cell Theory | All living things are made up of cells; the cell is unit of structure and function in all living things; all new cells come from previously cells |
| Cell Wall | Rigid structure which surrounds plant cells (provides support) |
| Organelle | Structure inside the cell that carries out a certain function |
| Nucleolus | A small rounded body within the cell nucleusfunctioning in ribosome manufacture |
| Smooth Endoplasmic Reticulum | Synthesizes lipids, phospholipids, and steroids |
| Golgi Body | Involved in glycosylation (i.e. adding carbohydrate to a protein), helps package molecules like proteins into vesicles for secretion, transport of lipids around the cell, and the creation of lysosomes |
| Lysosome | A cell organelle containig enzymes that break down food |
| Turgor Pressure | The pressure exerted by water inside the cell against the cell wall |
| Endocrine System | Secretes hormones that regulate body functions; coordinates other organ systems |
| Immune System | Helps the body protect against disease |
| Lymphatic System | System of vessels assisting the veins in recovering the body's tissues fluid and returning them to the heart |
| Homozygous | Same |
| Heterozygous | Different |
