Mr. Biando's Lab - Eukaryotic Cells
| Term | Definition |
|---|---|
| Cell Wall | A rigid structure that surrounds the cell membrane and provides support to the cell. |
| Cell Membrane | A proctective barrier that encloses the cell and seperates the cell's contents from it's environment. |
| Lipids | Organic compounds that do not dissolve in water which include fats and cholesterol. |
| Phospholipid | A fat that contains a phosphorus. |
| Hydrophobic | A molecule that fears water. |
| Hydrophillic | A molecule that loves water. |
| Cytoskeleton | A web of proteins in the cytoplasm that gives structure to the cell and helps move some cells move. |
| Nucleus | A large organelle in a eukaryotic cell that contains DNA. |
| Nucleolus | A dark area within the nucleus where ribosomes are made. |
| Ribosomes | Cell organelle composed of RNA and protein; the site of protein sythesis. |
| Amino acid | An organic molecule that is used to make proteins. |
| Endoplasmic Reticulum | A system of membranes that is found in a cell's cytoplasm and that assists in the production, processing, and transport of proteins and in the production of lipids. |
| Rough ER | Endoplasmic reticulum found near the nucleus and is covered with ribosomes. |
| Smooth ER | Endoplasmic reticulum that lack ribosomes and help make lipids and break down materials. |
| Mitochondrion | In eukaryotic cells, the cell organelle that is surrounded by two membranes and that is the site of cellular respiration. |
| adenosine triphosphate | ATP |
| Chloroplasts | Organelles in plant and algae cells in which photosynthesis occurs. |
| Photosythesis | The process by which plants and algae use sunlight, carbon dioxide, and water to make sugar and oxygen. |
| Chlorophyll | A green pigment found in chloroplasts. |
| Golgi Complex | Cell organelles that help make and package materials to be transported out of the cell. |
| Vesicles | Small sac-like compartments that surround materials to be moved into or out of the cell. |
| Vacuoles | A large vesicle found in plant and fungal cells that store water and other liquids. |
| Lysosome | A cell organelle that contains digestive enzymes. |
