Parts of A Cell
Biology
| Question | Answer |
|---|---|
| Cell Membranes | keeps all of the pieces of the cell inside the cytoplasm, however it is semi-permeable, wich allows movement in and out of the cell. It also serves as an attachment point for the intracellular cytoskeleton. |
| Cytoplasm | The fluid that fills a cell. Scientists used to call the fluid protoplasm. |
| RNA | Ribonucleic Acid. |
| The nucleus | Consists of the nuclear envelope, nucleolus, chromatin, and nucleoplasm. |
| Nuclear Envelope | Creates distinct nuclear and cytoplasmic compartments in eukaryotic cells. |
| chromosomes | DNA and proteins that condense to form chromosomes in eukaryotic cell division. Chromatin is located in the cell's nucleus. |
| Smooth Endoplasmic Reticulum (SER) | It is important in the storage of ions in solutions, and creation of steroids. |
| Rough Endoplasmic Reticulum (RER) | Important in the synthesis and packaging of proteins. |
| Vacuole | Found in plant cells, stores nutrients for the cell. |
| Cell Wall | The outest layer of a Plant cell, it provides protection from injury and support for the plant. |
| Cell membrane | also known as a unit membrane,it acts as a boundary layer to contain the cytoplasm within the cell. |
| Chloroplast | Only found in plant cells, this produces food in the cell. |
| Centriole | They come in a pair,and help the cell when it comes time to divide. |
| Ribosomes | The protein synthesizers. This crates protein in the cell, by connecting amino acids. |
| Lysosomes | hold enzymes that were created by the cell. It helps to digest food, and brake down the cell when it dies. |
| Peroxisomes | very similar to lysosomes, however its primary function is to digest fatty acids and alcohol. |
| Microtubules | They move vesicles, granules, organelles like mitochondria, and chromosomes via special attachment proteins |
| Cytoskeleton | This has a simmiler job as the cell wall in plant cell. It establishing the cells shape, and intracellular transport of organelles. |
