Cell parts/structure
Vocabulary
| Term | Definition |
|---|---|
| Plasma membrane | (cell membrane) thin coat of lipids surrounding and protecting the cell. |
| Cytoplasm | all the material inside the plasma membrane. Made up of fluid called cytosol. |
| Ribosome | structure in the cytoplasm where proteins are built (synthesized). |
| DNA | contains the genetic instructions that cells need to build proteins (structures and enzymes). |
| Prokaryote | (typical) – notice few internal structures and NO NUCLEUS |
| Nucleoid | the DNA (genetic material) of the prokaryotic cell. |
| Plasmid | small circular pieces of DNA, separate from the nucleoid material |
| Cell Wall | surrounds and protects the cell. |
| Capsule | polysaccharide coating prevents dehydration and aids the cell to “stick” |
| Pili | protein filaments used in movement or transfer of plasmids between prokaryotic cells. |
| Flagellum | organelle that allows movement |
| Eukaryote | notice many internal structures (organelles) and a NUCLEUS |
| Nucleus | double membrane bound structure the surrounds and protects the DNA (genetic material). |
| Cell Wall | surrounds and protects eukaryotic plant cells. |
| Membrane bound organelles | are structures that perform specific functions within the cell. Eukaryotic cells contain many different types of organelles, most of which are surrounded by a membrane similar to the plasma membrane. |
| Flagellum | organelle that allows movement, found mainly in single celled eukaryotic cells. |
