What is mitoplast

Options

A. Membraneless mitochondria
B. Mitochondria without inner membrane
C. Another name of mitochondria
D. Mitochondria without outer membrane

Answer

**Step-by-Step Solution:**

1. **Understanding Mitochondria**: Mitochondria are large cell organelles known as the "powerhouse of the cell" because they are responsible for producing ATP (adenosine triphosphate), which is the energy currency of the cell.

2. **Definition of Mitoplast**: The term "mitoplast" refers specifically to a form of mitochondria that has had its outer membrane removed. This process typically involves the use of a detergent, such as digitonin.

3. **Characteristics of Mitoplast**: A mitoplast retains the inner membrane and the matrix of the mitochondria but lacks the outer membrane. This means that while it can still perform some functions related to energy production, it is structurally different from a complete mitochondrion.

4. **Conclusion**: Therefore, a mitoplast can be defined as "mitochondria without the outer membrane."

**Final Answer**: Mitoplast is defined as mitochondria without the outer membrane.
