Biology Chapter 7 Vocab - Cells and Cell Transport

basic unit of structure and organization of all living organisms

• cell

• phospholipid

• lysosome

• centriole

flexible, selectively permeable boundary that helps control what enters and leaves the cell

• plasma membrane

• golgi apparatus

• cytoplasm

• nucleus

microscopic, unicellular organism without a nucleus or other membrane bound organelles

• prokaryotic cell

• eukaryotic cell

• organelle

• mitochondrian

Cell theory

• states that organisms are made of one or more cells

• the central membrane bound organelle that manages cellular functions and contains DNA

• condition of continuous, random movement of particles but no overall change in concentration of material

• diffusion of water across a selectively permeable membrane

unicellular organism with membrane bound nucleus and organelles; generally larger and more complex that a prokaryotic cell

• eukaryotic cell

• prokaryotic cell

• fluid mosaic model

• centriole

supporting network of protein fibers that provide a frame work for the cell within the cytoplasm

• cytoskeleton

• ribosome

• nucleolus

• mitochondrion

protein that moves substances or wastes through the plasma membrane

• transport protein

• Golgi apparatus

• lysosome

• vacuole

short, hairlike projection that functions in cell movement

• cilium

• flagellum

• centriole

• chloroplast

passive transport of ions and small molecules across the plasma membrane by transport proteins

• facilitated diffusion

• simple diffusion

• endocytosis

• exocytosis

a solution with the same concentration of water and solutes as inside a cell, resulting in the cell retaining its normal shape because there is no net movement of water.

• isotonic solution

• hypotonic solution

• hypertonic solution

• osmosis
