Respuesta :

Answer:

1. E (Interphase)

2. D (Anaphase)

3. A (Prophase)

4. B (Telophase)

5. C (Metaphase)

Explanation:

This question depicts the five stages that occur in cell division (Mitosis). Prior to the actual division of the cell, a resting and preparatory phase occurs.

1. Interphase: This phase is called resting phase because the cell prepares itself for the division about to occur. Interphase is mainly characterized by the duplication of the genetic material (DNA) that occurs specifically in the S-phase.

3. After the interphase stage, comes the PROPHASE stage where the chromatin material (DNA) condenses into chromosomes, which are more visible as a X-shaped structure. The spindle apparatus, which forms the microtubules that attach to each chromosome for separation, also forms at the Prophase stage.

5. The spindle microtubules attach to the kinetochores of each chromosome and aligns them in the middle of the cell called METAPHASE PLATE. This stage is called METAPHASE.

2. The spindle microtubules on each pole of the cell then pulls the chromosomes apart towards each end of the cell. This occurs during the ANAPHASE stage.

4. After the chromosomes have been separated to opposite poles of the cell, nuclear envelopes/membrane reforms around each chromosome in order to separate the nuclear material (chromosomes) from the cytoplasm. The cell plate, unique to plant cells also forms at the center of the cell in order for cytokinesis (division of cytoplasm) to occur. This stage is called TELOPHASE stage.
