Active transport

Passive transport

• Uses ATP to pump molecules upwards

• Molecules move downwards along the concentration gradient

• Cell membrane pump, endocytosis, and exocytosis are few transport types.

• Osmosis, diffusion and facilitated diffusion are few types.

• Complex sugars, ions, large cells, and proteins are few particles gets transported.

• Solubles like oxygen, carbon dioxide, monosaccharides, sex hormones, and water, etc are few particles that get transported.

• The main function is to transport molecules via the cell membrane.

• The main function is to maintain dynamic equilibrium of gases, water, nutrients, etc.
