Cells- Chapter 3
Term | Definition |
---|---|
cytoskelaton | network of protein tubes that give the cell shape, support, and mobility |
cell wall | give shape and protection; small openings allow for material to pass in/out |
chromatin | contains genetic material for protein synthesis |
plastids | where plants create and store chemical compounds |
ribosomes | where proteins are made |
vesicles | transports material to be excreted or taken in by the cell; created by cell membrane |
mitochondria | breaks down organic molecules making ATP energy for the cell |
lysosomes | contains enzymes for digesting food |
nuclear envelope | selectively permeable allowing only certain materials to enter/exit the region where DNA is kept |
cell membrane | separates internal/external environment |
golgi appartus | modifies, packages, stores, and transports lipids made by the smooth ER |
cilia | short, hair-like structures on the cell surface for movement |
nuclear pores | allows RNA and waste to leave, but DNA will not fit through |
chromoplasts | gives fruits, vegetables, and plants their color |
chloroplasts | produced by the liver, vesicles that break down dead material to detoxify the cell |
peroxisomes | fluid-filled sack where water, food, ions, waste, and sometimes poison, are stored |
cytoplasm | fluid that cushions and protects against the organelles |
necleolus | dark center of nucleus, information to make ribosomes |
microtubules | thick hollow proteins that make the skeleton of the cell that are tracks for movement in the cell |
amyloplasts | also called leucoplasts, store starch for food |
flagella | a "tail" used for movement |
smooth ER | an organelle made by the liver, creates lipids for detoxification of the cell |
centrosome | a type of cytoskeleton near the nucleus and aids in cell division |
nucleus | "control center" for cell that stores hereditary info and has a double membrane |
chloroplasts | plastid responsible for creating food, contains chlorophyll and has its own DNA |
microfilaments | cytoskeleton type responsible for cell being able to change shape |
rough ER | continuous from the nuclear membrane, creates membrane proteins |
