Definition of Organelle

An organelle is a subcellular entity present in a cell that is responsible for performing one or more specified jobs. It works in the cell exactly the same way an organ works in a body. These subcellular entities are also termed as vesicles. All the activities of a cell are divided among these organelles. This is why it is said that there is a division of labor in a cell. These organelles are bounded by a membrane that separates the product of one organelle from the other.


Examples of Organelle:

The mitochondrion, chloroplast, nucleus, endoplasmic reticulum etc. all are the examples of organelles. The mitochondrion is responsible for cellular respiration and is termed as a powerhouse of the cell. The chloroplast carries out the process of photosynthesis. The nucleus contains the genetic material.
