Higher plants differ from animals in having

Options

A. Spindle microtuble
B. Anastral mitosis
C. Kinetochores
D. Disappearance of nucleolus during prophase

Answer

To answer the question "Higher plants differ from animals in having," we need to focus on the differences in cell division between higher plants and animals. Here’s a step-by-step breakdown of the solution:

### Step 1: Understand the Types of Cell Division
- Both higher plants and animals undergo cell division, primarily through mitosis and meiosis. Mitosis is the type of cell division that results in two identical daughter cells.

### Step 2: Identify Key Differences in Mitosis
- In animals, during mitosis, there are structures called astral rays that help in the separation of chromosomes. These are star-shaped structures that form around the centrosome.

### Step 3: Recognize the Absence of Astral Rays in Plants
- In contrast, higher plants do not have these astral rays during mitosis. Instead, they undergo what is known as an anastral mitosis, meaning that the spindle fibers are present, but the astral rays are absent.

### Step 4: Conclusion
- Therefore, the significant difference between higher plants and animals in terms of cell division is that higher plants exhibit anastral mitosis, while animals exhibit amphiastral mitosis (where astral rays are present).

### Final Answer
- Higher plants differ from animals in having anastral mitosis.
