The stage at which cytokinesis begins in plant cells is

Options

A. Anaphase
B. I-phase
C. Late Metaphase
D. Telophase

Answer

To determine the stage at which cytokinesis begins in plant cells, we can follow these steps:

### Step 1: Understand the Cell Cycle
The cell cycle consists of several stages, including interphase (G1, S, G2) and the mitotic phase (M phase), which includes karyokinesis (nuclear division) and cytokinesis (cytoplasmic division).

**Hint:** Remember that the cell cycle is divided into interphase and the mitotic phase.

### Step 2: Identify the Stages of Mitosis
During the M phase, mitosis occurs, which is divided into several stages: prophase, metaphase, anaphase, and telophase.

**Hint:** Recall the order of the stages of mitosis: prophase, metaphase, anaphase, telophase.

### Step 3: Focus on Telophase
Telophase is the final stage of mitosis. During this phase, the chromosomes reach the opposite poles of the cell, and the nuclear envelope begins to reform around each set of chromosomes.

**Hint:** Telophase is characterized by the reformation of the nuclear envelope and the preparation for cytoplasmic division.

### Step 4: Understand Cytokinesis
Cytokinesis is the process that follows karyokinesis and involves the division of the cytoplasm to form two daughter cells. In plant cells, this process involves the formation of a cell plate that eventually develops into the cell wall.

**Hint:** Cytokinesis is the division of the cytoplasm and occurs after the nucleus has divided.

### Step 5: Conclusion
Based on the understanding of the cell cycle and the stages of mitosis, we conclude that cytokinesis begins during the telophase stage in plant cells.

**Final Answer:** The stage at which cytokinesis begins in plant cells is **Telophase (Option D)**.
