Which of the following organelle is called as the power house of a cell?Question 7Answera.Ribosomeb.Mitochondriac.Cytoplasmd.Nucleus

The organelle that is often referred to as the "powerhouse of the cell" is the Mitochondrion. Here's a step-by-step explanation:

1. Each cell in an organism's body has several different organelles, each with its own specific function.

2. The mitochondrion is one such organelle. It is often referred to as the "powerhouse of the cell" because it is responsible for producing the cell's energy.

3. This energy is produced through a process called cellular respiration, where glucose (a type of sugar) and oxygen are used to create ATP (adenosine triphosphate), which is the energy currency of the cell.

4. The more active a cell (like a muscle cell), the more mitochondria it will have to meet its energy needs.

So, the answer is b. Mitochondria.
