Biology
terms for a cell
| Term | Definition |
|---|---|
| mitochondria | Job: where cellular respiration happens-breaks down food; powerhouse |
| Golgi Apparatus | Job: gets vesicles of protein from the ER. Processes, sorts, & ships proteins where needed |
| Lipid Bilayer | the 2 layers of phospholipids that make up a cell membrane |
| centrosome/ centrioles | AnimalCellOnly! Job: appear during cell division; help cell divide by pulling chromosomes apart |
| Lysosome | AnimalCellOnly!.Job: can do programmed cell death;break down dead things (food, bacteria, old cell parts, ect) |
| cell (plasma) membrane | Job: controls what goes in&out of cell |
| Cilium | A short, hair-like extension of a cell used either for movement or as a censory organelle |
| chromatin | The genetic material of eukaryotic cells consisting of DNA and associated protiens |
| Nucleolus | Job: makes rRNA which makes ribosomes;assembles ribosomes |
| Nucleus | Job: protects DNA that controls activities of cell |
| central vacuole | PlandCellsOnly!Job:storage center |
| cell wall | PlantCellsOnly! protect and maintain shape |
| granum | stack of disk-shaped thylokoids within a chlolroplast |
| leucoplast | stores startches, lipids, and proteins |
| chloroplast | where photosynthesis happens; converts light energy from sun-chemical energy in sugar |
| RER | makes proteins/ribosomes; packages them for secretion |
| SER | makes lipids(membrane) |
| ribosomes | make proteins |
| capsule | a protective coating found outside the cell wass of many bacteria |
| nucleoid | the non-membrane region in prokaryotic cells that contains most of the genetic material |
| flagellus | move entire cell through extra cellular fluid |
| cytoskeleton | give the cell shape; can also move organelles around; provide structural support for animal cells (who don't have a cell wall) |
| cytoplasm | holds everything in place |
| eukaryote | an organism with cells having a true nucleus as well as membrane-bound organelles |
| prokaryote | an organism with cells lacking a true nucleus and mebrane-bound organelles |
| organelle | specialized structures within the cell that work together to help the cell function |
| organ system | a group of two or more organs that work together to perform a particular function |
| organ | a structure made of two or more tissues that work together to perform a particular function |
| tissue | a group of cell that are specialized to perform a particular function |
| multicellular organism | composed of many cells that may organize into tissues-organs=organ systems |
| colony | cells divide labor but each cell can detach and live on their own |
| unicellular organism | composed of one cell |
| cell theory | all living things are made of cells; cells are the basic unit of life; all cells come from other cells |
