Active Transport: Moving Substances Against Concentration Gradient

The video explains how substances move in and out of cells through diffusion, osmosis, and active transport. Active transport is highlighted as a process that moves substances against a concentration gradient using energy from respiration. Examples include mineral ion uptake in plant root hair cells and sugar absorption in the human gut.

How do plants utilize active transport to absorb mineral ions?

In what way does active transport in the gut benefit the human body?
