How does a single celled organism get its nutrients?

Answer 1

Easy!!

diffusion.. because single celled organisms have a large surface area to volume ratio meaning that there exchange surface is large enough to allow efficient diffusion fast enough to keep the cells alive (1 cell.. lol ). they also aren't very active they can rely on diffusion alone to take up water and other important solutes..

Diffusion through osmosis occurs in single celled organisms when they have a lower water potential inside the cell than outside so water flows into the cell (down the concentration gradient) via a partially permeable membrane.

hope that helped

Answer 2

A single-celled organism can obtain nutrients through processes such as diffusion, osmosis, phagocytosis, or pinocytosis. These organisms take in nutrients from their environment through their cell membrane and use them to carry out essential functions such as growth and reproduction.
