active transport

this means that it is going from lower to higher concentration

it requires energy from the cell and always takes place across a membrane

it requires special proteins that sit in the membrane to transfer the molecules

this is a process in the mitochondria where glucose is broken down to make energy

the energy is stored in molecules called ATP (adenosine triphosphate)

• they take the energy to different parts of the cell

these cells absorb water and mineral ions

some minerals that are needed by the plant cannot be absorbed through diffusion because they are in higher concentration inside the cell than outside

these cells have lots of mitochondria to make energy
