The basic unit of structure and function in living things
cell membrane
A cell structure that controls which substances can enter or leave the cell.
cell wall
A rigid layer that surrounds the cells of plants and some other organisms.
Cytoplasm
A jellylike fluid inside the cell in which the organelles are suspended
Mitochondria
Powerhouse of the cell - creates energy in the form of ATP
Ribosomes
Makes proteins
prokaryotic cell
cell that does not have a nucleus or other membrane-bound organelles.
Eukaryotic cells
Contain a nucleus and other organelles that are bound by membranes.
Lysosomes
An organelle containing digestive enzymes; gets rid of waste and damaged organelles
Osmosis
Diffusion of water through a selectively permeable membrane
Diffusion
Movement of molecules from an area of higher concentration to an area of lower concentration.
Endoplasmic Reticulum
A system of membranes that is found in a cell's cytoplasm and that assists in the production, processing, and transport of proteins and in the production of lipids.
Chloroplast
An organelle found in plant and algae cells where photosynthesis occurs
Vacuole
A sac inside a cell that acts as a storage area
cell nucleus
an organelle in a cell that holds the cells DNA
Centriole
Cell organelle that aids in cell division in animal cells only
3 things plant cells have tat animal cells do not
chloroplasts, cell wall, large central vacuole
2 things animal cells have that plant cells don't
lysosomes and centrioles
phospholipid bilayer
Cell membrane layers composed of phospholipid molecules arranged with polar heads facing the outside and nonpolar tails facing the inside.
active transport
Energy-requiring process that moves material across a cell membrane against a concentration difference
passive transport
the movement of substances across a cell membrane without the use of energy by the cell
concentration gradient
A difference in the concentration of a substance across a distance.
