2
in what type of respiration is oxygen needed?
aerobic respiration
what do both fermentations not require?
oxygen
what is the cell membrane made up of ?
proteins and phospholipids
what is passive transport?
the movement of substances from a high to low concentration
it requires no energy
what is diffusion?
the movement of molecules down a concentration gradient, high to low concentration
it requires no energy
what substances go inside the cell?
amino acids, water, glucose ,oxygen
what is osmosis?
the movement of water molecules from a high to low concentration
what happens to a plant cell when it’s placed in a strong sugar solution?
becomes plasmolysed
what happens to a red blood cell when it’s placed in a strong salt solution?
it shrinks
what is active transport?
the movements of molecules and ions from a low to high concentration
it requires energy
name 3 organelles found in a plant cell but not an animal cell?
chloroplasts, vacuole, cell wall
what do bacterial cells not have?
nucleus and mitochondria
what is the function of the cell wall?
support and structure the cell
