| Term | Definition |
|---|---|
| chlorophyll | Green pigment that captures the light energy that drives the light reactions of photosynthesis |
| mitochondria | cellular organelles responsible for carrying out cellular respiration, resulting in producing ATP, the cells main energy-carrying molecule |
| central vacuole | large plant cell organelle that regulates the cell's compartment, holds water, and plays a significant role in cell growth as the site of macromolecule degradation |
| motor proteins | act as the driving force behind the active transport of proteins and vesicles in the cytoplasm move structures within cell |
| capsule | sticky outer layer of polysaccharides helps in attachment to nutrients and surfaces |
| pili | short hair-like structures on the cell surface of prokaryotic cells conjugation (transfer plasmids to other bacteria) |
| fimbriae | short bristle fibers that are on bacterial surface that help with attachment to another surface |
| endomembrane system | group of organelles and membranes in eukaryotic cells that work together modifying, packaging, and transporting lipids and proteins |
| chloroplast | plant cell organelle that carries out photosynthesis |
| endoplasmic reticulum | series of inter-connected membranous structures within eukaryotic cells that collectively modify proteins and synthesize lipids |
