Why is cell the basic unit of life class 8?

A cell is the smallest unit of life and is capable of all living functions. Cells are the building blocks of life. This is the reason why cells are referred to as the basic structural and functional units of life. All cells vary in their shape size and activity they perform.

Why is cell the basic unit of life class 9?

The smallest functional unit of life is cell discovered by Robert Hooke in 1665. A cell can independently perform all necessary activities to sustain life. Hence cell is the basic unit of life. There are two types of cells → plant cell and animal cell.

What is called the powerhouse of the cell?

Mitochondria are tiny organelles inside cells that are involved in releasing energy from food. This process is known as cellular respiration. It is for this reason that mitochondria are often referred to as the powerhouses of the cell.

Why mitochondria is known as powerhouse of cell?

Mitochondria are often called the “powerhouses” or “energy factories” of a cell because they are responsible for making adenosine triphosphate (ATP) the cell’s main energy-carrying molecule. … Cellular respiration is the process of making ATP using the chemical energy found in glucose and other nutrients.
