Question

Which organelle is known as the powerhouse of the cell? Why?

Answer 1

Hint:This cell organelle is sausage-shaped or cylindrical that synthesises energy in the form of ATP. They have their own DNA and ribosomes. Thus they are able to make some of their own proteins.

Complete answer:
The cell is the basic building block of life. There are certain components within a cell called cell organelles that perform specific functions such as making new material in the cell, removing the waste material from the cell, etc. Because of these organelles, the cell is able to live and perform all its functions.
Mitochondria are double membrane bound cell organelle. Each mitochondrion is a dual membrane-bound structure with an outer membrane and an inner membrane that separates its lumen into two aqueous compartments, the outer compartment and the inner compartment. The outer membrane is very porous and the inner membrane is tightly folded. These folds have a broad surface area for ATP-generating chemical reactions. Both membranes have their own unique enzymes associated with mitochondrial activity. Mitochondria provides the energy required for various chemical processes crucial to life in the form of ATP (Adenosine Triphosphate) molecules. The body uses energy contained in ATP for the creation of new chemical compounds and for mechanical purposes. As a result, mitochondria are considered the powerhouse of the cell.

Note:All organisms are made up of cells or cell aggregates. Cells vary in shape, size and activity or function. On the basis of the presence or absence of a nuclear membrane and other organelles, the cells and therefore organisms may be called eukaryotic or prokaryotic.
