BOTANY

Detailed explanation-1: -They also aid in recycling proteins and digest worn-out cells. Hence, they are called ‘suicide bags of cells’. But they do not carry out photosynthesis.

Detailed explanation-2: -The lysosome helps in intracellular digestion. This is because digestion occurs within the lysosome, which is inside the cell and not outside. Hence option D is correct.

Detailed explanation-3: -Functions of lysosomes include both intracellular digestion as well as extracellular digestion. Intracellular Digestion: Digestion of foreign material or digestion of dead cell particles takes place. Extracellular Digestion: Lysosomes of osteoclast (bone-eating cells) break down unwanted parts of the bone.

Detailed explanation-4: -Lysosomes assist in the intracellular digestion of worn-out cellular organelles and materials taken into the cell by endocytosis.
