The diffusion of water across a partially permeable membrane from higher to lower water potential

Which feature is unique to active transport?

It moves substances against the gradient using energy from respiration

A plant cell is placed in pure water. What happens?

It becomes turgid as water enters by osmosis

Shrink as water leaves by osmosis

A steeper concentration gradient

Its surface area to volume ratio is too small for diffusion across the body surface to be enough

A large surface area, thin walls and a good blood supply

Active transport requires energy from respiration but diffusion and osmosis do not
