A.


C.

Answer 1

Step-by-step explanation:

Cell division involves formation of two daughter cells from a single parent cell. The two main phases of cell division are interphase and M (mitosis). Interphase represents the longest phase of cell division, while mitosis is smallest phase of cell division.

Interphase which includes G1 phase, S phase, amd G2 phase, during which cell prepares itself to divide and replicates its genetic material. During mitosis, actual cell division (division of nucleus and cytoplasm) takes place to form two daughter cells.

Hence, letter A represents G1 phase, letter B represents S phase, letter C represents G2 phase, and letter D represents M phase (division phase).

Thus, the correct answer is option (D).

Answer 2

Cell division is represented in the Figure by the letter D.

The cell cycle alternate two principal stages: interphase and M (mitosis) phase.

Interphase is in turn divided into three phases:

• Growth 1 phase or 'G1 phase' (represented in the Figure by the letter A).

• Synthesis phase or 'S phase', in which DNA replication occurs (represented by the letter B).

• Growth 2 phase or 'G2 phase' (represented by the letter C).

Moreover, the M phase of the cell cycle is in turn divided into several phases:

1. Prophase
2. Metaphase
3. Anaphase
4. Telophase
5. Cytokinesis

In conclusion, cell division is represented in the Figure by the letter D.
