Detailed explanation-1: -Osmosis, facilitated diffusion and simple diffusion do not require energy. They come under passive transport.

Detailed explanation-2: -Osmosis, facilitated diffusion and simple diffusion do not require energy.

Detailed explanation-3: -1 Lipid diffusion (simple diffusion) Passive transport requires no energy input, as compounds are able to move freely across the membrane based only on a favourable concentration gradient (Figure 1.11).

Detailed explanation-4: -Passive transport, most commonly by diffusion, occurs along a concentration gradient from high to low concentration. No energy is necessary for this mode of transport.

Detailed explanation-5: -Answer and Explanation: The correct answer is option C. Endocytosis is a form of active transport. Endocytosis is the biological process wherein molecules in the extracellular environment are taken in by the cell.
