Detailed explanation-2: -An organelle is a subcellular structure that has one or more specific jobs to perform in the cell, much like an organ does in the body. Among the more important cell organelles are the nuclei, which store genetic information; mitochondria, which produce chemical energy; and ribosomes, which assemble proteins.

Detailed explanation-3: -(OR-guh-NEL) A small structure in a cell that is surrounded by a membrane and has a specific function.

Detailed explanation-4: -Organelles are special and organized structures seen in living cells. Some of the membrane-bound organelles are vacuoles, nucleus, chloroplasts, lysosomes etc. The nucleus is the largest organelle in the cell.

Detailed explanation-5: -These organelles are the recycling center of the cell. They digest foreign bacteria that invade the cell, rid the cell of toxic substances, and recycle worn-out cell components. Mitochondria. Mitochondria are complex organelles that convert energy from food into a form that the cell can use.
