Question | Answer |
movement of particles from areas of high concentration 2 areas of low concentration | diffusion |
energy is not required for _________ | difusion |
the diffusion of water through a semi-permiable membrane | osmosis |
water is made of particles called________ | molecules |
half | semi |
only certain substances can pass through | semipermiable |
osmosis is important to____ _____&___ _______ | life processes& cell funtion |
passageways in the cell membrane made of protiens | channels |
movement of substances across a cell membrane without the use of energy by the cell | passive transport |
the movement of substances across the cell membrane(requires cell to use energy) | active transport |
state of balance | equilibrium |
process that a cell surronds particle in a vesicle 2 bring particle in the cell | endocytosis |
what 2 ways are ways of bringing large particles in 2 or out of the cell? | endocytosis & exocytosis |
process that a cell releases a particle by vesicle that then moves 2 cell surface & fuses with cell mebrane | exocytosis |
less crowded | low concentration |
crowded | high concentration |
water | hydro |
fear | phobic |
2 love | philic |
how is osmosis diff. from diffusion? | a.diffusion is movementof particles/ osmosis is movement of H2O b.osmosis envolves movement across a Semi- permiable membrane / diffusion dosn't |
more solute outside cell, h2o flows outside | hypertonic |
more solute inside cell,h2o flows inside | hypotonic |
same amt.of solute 7 H2O on both sides of cell | isotonic |
what is the formula for photosynthesis? | CO2&H2O sunlight C6H12O6 &O2 |
process by which plants capture energy from the sun& convert it into food(glucose) | photosynthesis |
pigment in the chloroplasts that absorbs sunlight | chlorophyll |
glucose is a______ | carb. |
glucose& O2-----ATP& (CO2 & H2O) | celular resiration |
in eukaryotes c.r. takes place in the_______? | mitochondria |
in prokaryotes c.r. takes place in the ______? | cell membrane |
process by which cells use oxygen 2 produce ener.from food | cellular respiration |
the breakdown of food without the use of oxygen | fermintation |
