Detailed explanation-1: -Besides the nucleus, two other organelles-the mitochondrion and the chloroplast-play an especially important role in eukaryotic cells. These specialized structures are enclosed by double membranes, and they are believed to have originated back when all living things on Earth were single-celled organisms.

Detailed explanation-2: -Answer and Explanation: A specialized structure that performs important cellular functions within a cell is called an organelle. Examples of organelles include the double membrane-bound mitochondrion, which contains many enzymes necessary to produce large amounts of ATP.

Detailed explanation-3: -Organelles are specialized structures that perform various tasks inside cells.

Detailed explanation-4: -Golgi apparatus, Mitochondria, Ribosomes, Nucleus are parts of Eukaryotic Cells.

Detailed explanation-5: -mitochondrion) is an elongated, double membrane structure with numerous cristae within its inner membrane. In addition to the membrane bound ATP synthase proteins that facilitate ATP production, mitochondria are the only organelles that contain their own DNA material and is therefore capable of replication.
