Amitosis is a characteristic of

Options

A. Higher plants
B. Higher animals
C. Bryophyta
D. Lower organisms

Answer

**Step-by-Step Solution:**

1. **Understanding Amitosis:**
- Amitosis is a type of cell division that occurs without the typical processes seen in mitosis. It is characterized by the direct division of the nucleus and cytoplasm.

2. **Characteristics of Amitosis:**
- In amitosis, there is no formation of a mitotic spindle.
- The nuclear envelope does not break down as it does in mitosis.
- Chromosomes do not condense in the same way they do during mitosis.
- It is often referred to as "direct cell division" or "closed mitosis."

3. **Identifying Organisms:**
- Amitosis is primarily observed in lower organisms, such as certain protozoa and bacteria.
- Higher plants and animals typically undergo mitosis, which is a more complex process involving the formation of a spindle apparatus and a well-defined mitotic phase.

4. **Conclusion:**
- Based on the characteristics of amitosis and the types of organisms that exhibit this form of cell division, the correct answer to the question is "lower organisms."

**Final Answer:**
Amitosis is a characteristic of lower organisms.
