Document Summary

Capsule: the cell wall of some prokaryotes and is sticky, protecting the cell & enabling it to adhere to substrates or other cells. Pilus: basteria; short projections that can attach to surfaces of other prokayotes. Lysosome: break down & recycle foreign or wornout cellular substances. Nuclear envelope: substances between the nucleus & the cytoplasm. Central vacuole: as nutrients or water (specific to plant cells) Fluid mosaic: past one another, and mosaic bc of the diversity of proteins that float in the phospholipid sea Membrane proteins: membranes; help regulate passage of material into & out of the cell. Passive transport: an area of higher concentration to an area of lower concentration. Diffusion: concentration to an area of lower concentration, think of a perfume diffuser. Osmosis: higher concentration to an area of lower concentration. Facilitated diffusion: for ex, theyre too large), such substances can be passed thru with this transport method, through specific transport proteins embedded in the membrane.
