cells and transport Flashcards
cells
the basic unit of life
cell membrane
the organelle that allows material to enter and exit the cells. found in all cells.
cytoplasm
the filling of a cell
nucleus
the organelle that contains genetic material
mitochondria
the organelle responsible for making the cells energy
vacuole
the organelle that holds water and other materials. larger in plant cells.
ribosomes
the organelle that produces proteins in the cell
cholorplast
the organelle that produces sugar using sunlight in autotrophs(plants)
cell wall
an organelle that protects plant cells
unicellular
organisms is composed of only one cell and is microscopic
multicellular
organism is composed o many specialized cells
-karyo
the Greek root which means nucleus
prokaryotic
cells that have no nucleus or specialized organelles(besides or ribosomes), like bacteria
eukaryotic
cells that have a nucleus and many organelles, like plant and animal cells
flagellum(plural flagella)
a long, whip like tail which some cells use to move
cilia
short, hair like projections that some cells use to move
pseudopod
a “fake foot” made of cytoplasm, which can be used to move or engulf food
structure
the way something looks or the organelles that it processes
function
the way something works or the job it does
specialized
a cell that has a specific structure and function in a multi-cellular organism
DNA
the molecule that carries genes stored in the nucleus, used to produce proteins and code for traits
osmosis
passive diffusion of water
diffusion
molecules moving with their concentration gradient
active transport
molecules being pumped against their concentration gradient
endocytosis
cell consuming something and engulfing it with plasma membrane
