Cell Transport Flashcards
Cells rely on a supply of materials entering through their membranes and _
Being moved between organelles
Materials entering and being moved around cell relies on a range of _
Passive and active transport systems
When substance is free to move, it will tend to drift from _ to _
(Diffusion)
High concentration
Not high concentration
_ is an entirely passive process with no input of energy
Diffusion
Difusión will happen faster when the material and its medium are
Warmer
Diffusion always occurs in the same direction along a concentration gradient with _
Molecules moving from high to low concentrations
Diffusion can occur in a mixture of gases like air, or in more complex solutions like _
Cytoplasm
Cytoplasm contains many dissolved _
Substances
Skin wrinkles in water, partly due to _
Influx of water by osmosis
