Organelles
jelly like substance that contains dissolved molecules and amino acids
cytosol
transports proteins and other materials through the cell
vesicles
Transport that requires energy
active transport
transport of large molecules or large amounts of molecules requiring energy
bulk transport
membranous sacs that carry proteins between organelles
transport vesicles
extension of cell membranes to increase surface area for absorption
microvilli
modifies and packages proteins to be released from the cell
Golgi body
transport that requires no energy
passive transport
a stationary cell engulfing a large molecule
pinocytosis
membranous sacs that carry proteins from the Golgi body to the cell membrane
secretory vesicles
extensions of cell membrane which sweep materials across cell surface
cilia
makes and modifies proteins for use outside cell
Rough endoplasmic reticulum
movement of molecules through a membrane from an area of high concentration to low concentration
diffusion
a moving cell engulfing a large molecule or bacteria
phagocytosis
the process of a cell destroying its own nucleus, shriveling and dying
apoptosis
surrounds cell and protects it from the outside world; allows certain substances to enter or exit cell
cell membrane
membrane full of enzymes to digest worn out cell parts or bacteria
lysosomes
movement of molecules from an area of low concentration to high concentration requiring an ATP pump
primary active transport
any type of active transport in which the cell membrane folds inwards bringing something into the cell
endocytosis
the number of chromosomes in most cells of the body
46
produces ATP
mitochondria
organizes fibers used to separate chromosomes during cell division
centrioles
movement of water through a semipermeable membrane from an area of low solute concentration to an area of high solute concentration
osmosis
vesicles in the cell merging with the cell membrane to release their contents outside of the cell
exocytosis
the number of chromosomes in gametes
