A cell organelle can be defined as a membrane bound structure that is present in within a cell and carry out specific functions. There are several cell organells in a eukaryotic cells and each one have distinct functions. They include,
Nucleus- Carries DNA which contains the genetic information
Mitochondria- Known as the 'power house of a cell'. Produces energy in the form of ATP molecules that is required for the functioning of entire cell.
Ribosomes- They are invoved in protein synthesis.
Lysosyme- It contains digestive enzymes that are required to digest the food particles.
Golgi complex- They process and pack proteins.
Endoplasmic reticulam- These are long membraneous organelle and reach out to almost every part in a cell. So, it has function in transporting all kinds of molecules around the cell.
Vacoules- Required to store food.
In case of prokaryotes there are no membrane bound cell organneles but, non membraneous ribosome can be present.
Plant cells also has organelles like nucleus, mitochondria, choloplast (Carries out photosynthesis).
Each of these cell organelles within a cell are essential for a cell. Like, in an industry there are lot of people working in different departments and thier group work is essential for the winning of the industry, cells also posses the same. A cell has different organells that carries out distint functions and their working together is essential for a cell's survival. Loss of function in any of the organelle can cause serious damaging effects to a cell.
Hence, their specific function ( 'referred to as Division of Labour') is necessary to make a cell survive.
