DIFFUSION
The movement of particles from region of higher density to regions of lower density
OSMOSIS
The diffusion of water through a semipermeable membrane
PASSIVE TRANSPORT
The movement of substance across a cell membrane without the use of energy by the cell
ACTIVE TRANSPORT
The movement of substance across the cell membrane that requires the cell to use energy
ENDOCYTOSIS
the process by which a cell membrane surrounds a particle and encloses the particle in a vesicle to bring the particle into the cell
EXOCYTOSIS
The process in which a cell is releases a particle by enclosing the particle in a vesicle that then moves to the cell surface and fuses with the cell membrane
CELLULAR RESPIRATION
The process by which cells use oxygen to produce energy from food
FERMENTATION
The breakdown of food without the use of oxygen
CELL
The smallest functional and structural unit of all living organisms, usually consists of a nucleus, cytoplasm, and a membrane
CELL MEMBRANE
A phospholipid layer that covers a cell's surface; acts as a barrier b/w the inside of a cell and the cell's environment.
Protective layer that covers the cell's surface
ORGANELLES
One of the small bodies in a cell's cytoplasm that are specialized to perform a specific function
(they carry out various life processes within the cell)
NUCLEUS
its a eukaryotic cell,
a membrane-bound organelle that contains the cell's DNA and that has a role in processes such as growth, metabolism, and reproduction
PROKARYOTE
an organism that consists of a single cell that does not have a nucleus

(LIKE bacteria)
EUKARYOTE
an organism made up of cells that have a nucleus enclosed by a membrane; these include animals, plants, and fungi. NOT bacteria or archaea
CELL WALL
a rigid structure that surrounds the cell membrane and provides support to the cell
RIBOSOME
Cell organelles composed of RNA and protein the site of protein systhesis

(organelles that make proteins)
ENDOPLASMIC RETICULUM
a system of folded membranes in which proteins, lipids, and other materials are made. (where chemical reactions take place in the cell)
MITOCHONDRIA
It's the main power source of the cell

its an organelle in which sugar is broken down to produce energy
GOLGI COMPLEX
Cell organelle that helps make and package materials to be transported out of the cell
LIPIDS
are found within the cell membrane. These include fats and cholesterol that do not dissolve in water
CELLULOSE
The cell walls of plants and algae that is made up of a complex sugar
CHITIN
the cell walls of fungi made of a complex sugar
AMINO ACIDS
Proteins are made within the ribosomes. Proteins are made of amino acids. A.A. are used to make proteins, all cells need proteins to live
NUCLEOLUS
Where a cell begins to make its
ribosomes p.70 see pic
CHLOROPLAST
Chlorophyll is found in chloroplast
CHLOROPHYLL
the main pigment used in photosynthesis, gives plants their green color
LYSOSOME
A cell organelle that contains digestive enzymes
