Diffusion is a passive transport of minerals from high to low concentration.
Osmosis is a passive transport of water from high to low concentration.
Active transport is the movement of ions or molecules across a cell membrane against a concentration gradient requiring energy.
Surface area to volume ratio measures the efficiency of diffusion, so large structures which have a small surface area: volume ratio will have a big distance between the surface and cell bodies…
