bulk transport
endocytosis and exocytosis
osmosis
Diffusion of water through a selectively permeable membrane
ribosomes
Makes proteins
vesicle
A membrane bound sac that contains materials involved in transport of the cell.
Cell Membrane
A cell structure that controls which substances can enter or leave the cell.
pinocytosis
A type of endocytosis in which the cell ingests extracellular fluid and its dissolved solutes.
peptidoglycan
A protein-carbohydrate compound that makes the cell walls of bacteria rigid
active transport
the movement of materials through a cell membrane using energy
eukaryotic
Has a nucleus
dynamic equilibrium
a state of balance between continuing processes
nucleolus
Makes ribosomes
cytosol
Fluid portion of cytoplasm
chitin
Polysaccharide found in arthropod exoskeletons and fungal cell walls.
facilitated diffusion
Movement of specific molecules across cell membranes through protein channels
active sites
the site on an enzyme that attaches to a substrate
cell membrane
A cell structure that controls which substances can enter or leave the cell.
Hypotonic
Having a lower concentration of solute than another solution
cytoplasm
the portion of the cell outside the nucleus
Plants
an organism that does photosynthesis, is multi-cellular and has cell walls
cellulose
A substance (made of sugars) that is common in the cell walls of many organisms
Multicellular
Consisting of many cells
exocytosis
Process by which a cell releases large amounts of material
endocytosis
process by which a cell takes material into the cell by infolding of the cell membrane
nucleus
Control center of the cell
Lysosomes
An organelle containing digestive enzymes
Vacuole
Cell organelle that stores materials such as water, salts, proteins, and carbohydrates
nucleus
Control center of the cell
Rough Endoplasmic Reticulum
An endomembrane system covered with ribosomes where many proteins for transport are assembled.
Diffusion
Movement of molecules from an area of higher concentration to an area of lower concentration.
biological catalyst
enzyme
Golgi apparatus
A system of membranes that modifies and packages proteins for export by the cell
Cell wall
A rigid layer of nonliving material that surrounds the cells of plants and some other organisms.
denatured
Change the shape of an enzyme so that it can no longer speed up a reaction.
prokaryotic
cells that do not have a nucleus
Phagocytosis
A type of endocytosis in which a cell engulfs large particles or whole cells
substrates
the reactants of enzyme-catalyzed reactions
Centrioles
Cell organelle that aids in cell division in animal cells only
organelles
Structures specialized to perform distinct processes within a cell.
phospholipids
a lipid containing a phosphate group in its molecule
selectively permeable
some substances can pass across them and others cannot
aqueous
made from water
fungi
An organism that absorbs nutrients from the environment.
bacteria
single-celled organisms that lack a nucleus; prokaryotes
chromosomes
threadlike structures made of DNA molecules that contain the genes
hypertonic
Having a higher concentration of solute than another solution.
isotonic
when the concentration of two solutions is the same
Smooth Endoplasmic Reticulum
Makes lipids
enzyme
A type of protein that speeds up a chemical reaction in a living thing
Mitochondria
Powerhouse of the cell
Unicellular
Made of a single cell
