Cells have particular structures that perform specific jobs. These structures are known as ____
A
organs
B
tissues
C
systems
D
organelles
Explanation: 

Detailed explanation-1: -Organelles are specialized structures that perform various jobs inside cells. The term literally means “little organs.” In the same way organs, such as the heart, liver, stomach, and kidneys, serve specific functions to keep an organism alive, organelles serve specific functions to keep a cell alive.

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: -An organelle (think of it as a cell’s internal organ) is a membrane bound structure found within a cell. Just like cells have membranes to hold everything in, these mini-organs are also bound in a double layer of phospholipids to insulate their little compartments within the larger cells.

Detailed explanation-4: -Organelles are small structures within the cytoplasm that carry out functions necessary to maintain homeostasis in the cell. They are involved in many processes, for example energy production, building proteins and secretions, destroying toxins, and responding to external signals.

Detailed explanation-5: -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.
