HOW substance get transported in unicelluar organism?

Answer 1

In unicellular organisms, substances are primarily transported through processes like diffusion, osmosis, and active transport. Diffusion allows small molecules, such as oxygen and carbon dioxide, to move across the cell membrane from areas of higher concentration to lower concentration. Osmosis specifically refers to the movement of water across the membrane. Active transport requires energy to move substances against their concentration gradient, ensuring that essential nutrients are absorbed and waste products are expelled efficiently.
