hesi bio Flashcards
make ATP (organelle)
mitochondria
small particles found on rough ER. Site of protein synthesis.(organelle)
ribosomes
responsible for DNA activities. surrounded by nuclear envelope.(organelle)
nucleus
storage vesicles for digestive enzymes (organelle)
lysosome
produces protein. has ribosomes.(organelle)
rough er
endoplasmic reticulum(organelle)
transports substances within the cell
found only in the cells of plants. Photosynthesis occurs here(organelle)
chloroplasts
storage, modification, and packaging of secretory products (organelle)
Golgi apparatus
membrane bound organelles which contain powerful oxidative enzymes (organelle)
peroxisomes
store material, mostly in plants (organelle)
vacuole
function is cell division, only in animal cells (organelle)
centrosome & centriole
hair like extensions from the cytoplasm of the cell. allow movement and ingestion of unicellular organisms (organelle)
cilia and flagella
double layer of lipids which surrounds the cell. Membrane is semi permeable; permeable to water not solids.
cell membrane
the migration of molecules of ions, as a result of their own random movements, from a region of higher concentration to a region of lower concentration.
diffusion
the movement of water through a semipermeable membrane.
osmosis
type of transport: movement of ions and molecules AGAINST a concentration gradient. The cell must expend energy
active transport
type of transport, no energy is needed
passive transport
