What are Cell Organelles?
The cellular components are called cell organelles. These cell organelles include both membrane and non-membrane bound organelles, present within the cells and are distinct in their structures and functions. They coordinate and function efficiently for the normal functioning of the cell. A few of them function by providing shape and support, whereas some are involved in the locomotion and reproduction of a cell. There are various organelles present within the cell and are classified into three categories based on the presence or absence of membrane.
Organelles without membrane: The Cell wall, Ribosomes, and Cytoskeleton are non-membrane-bound cell organelles. They are present both in prokaryotic cell and the eukaryotic cell.
Single membrane-bound organelles: Vacuole, Lysosome, Golgi Apparatus, Endoplasmic Reticulum are single membrane-bound organelles present only in a eukaryotic cell.
Double membrane-bound organelles: Nucleus, mitochondria and chloroplast are double membrane-bound organelles present only in a eukaryotic cell.
- In all living organisms, cell is the smallest structural and functional unit of life .
- It is also known as building blocks of all living beings.
- Cells are basically of two types (on the basis of arrangement of nuclear structure) : Prokaryotic and Eukaryotic.
- A group of morphologically and functionally similar cell forms the tissue.
- Structures found inside the cells ( or subunits of cell) which have specific functions are called cell organelles.
- Some of the cell organelles are Vacuole, endoplasmic reticulum, mitochondria , plastids, golgi apparatus , lysosomes , nucleus etc.
