Answer:

Cell Organelle

A small organ-LIKE structure present inside the cell is called a cell organelle. It has a particular structural makeup and performs a specific function. Depending upon the presence or absence of membrane, cell organelles can be CLASSIFIED into three categories, namely:

Without membrane: Some cell organelles like ribosomes are not bounded by any membrane. They are present in prokaryotic as well as eukaryotic organisms.

Single membrane-bound: Some organelles are bounded by a single membrane. For example, VACUOLE, LYSOSOME, Golgi Apparatus, Endoplasmic Reticulum etc. They are present only in a eukaryotic cell.

Double membrane-bound: Cell organelles like mitochondria and chloroplast are double membrane-bound organelles. They are present only in a eukaryotic.Structure and Functions of Cells

Structure and functions of different cell inclusions are as follows-

They provide structure and support, facilitate growth through mitosis, ALLOW passive and active transport, produce energy, create metabolic reactions and aid in reproduction.
