Biology · Cell Cycle and Cell Division · NEET
NCERT lists three: (1) chromosomes cluster at opposite spindle poles and their identity is lost as discrete elements (they decondense), (2) a nuclear envelope develops around each chromosome cluster forming two daughter nuclei, and (3) the nucleolus, Golgi complex and ER reform. Learn these three lines exactly — NEET picks options directly from them.
In prophase the chromatin condenses into visible chromosomes and the nuclear envelope and nucleolus disappear. In telophase the reverse happens: chromosomes decondense and lose their individuality, and the nuclear envelope and nucleolus reappear. So telophase reverses prophase and reassembles the resting-nucleus structures.
No. Telophase completes karyokinesis, which is division of the nucleus, and gives two daughter NUCLEI inside one cell. The cell itself splits into two cells only during cytokinesis (cytoplasm division), which usually begins during telophase but is a separate step. This nucleus-vs-cell point is a common NEET trap.
The nucleolus disappears during prophase and reappears during telophase, along with the nuclear envelope. The Golgi complex and endoplasmic reticulum, which also broke down earlier, reform in telophase too.
No. In telophase the chromosomes decondense (uncoil) and can no longer be seen as separate discrete structures. Each set of chromatin collects at a pole. This is why late-telophase nuclei look like a normal interphase resting nucleus rather than showing distinct chromosomes.
Try the real previous-year questions from this chapter — each with the answer and a full solution.
Telophase is the last stage of karyokinesis (nuclear division). Cytokinesis (cytoplasm division) usually follows or overlaps with it to complete cell division.
The nuclear envelope, the nucleolus, the Golgi complex and the endoplasmic reticulum all reform during telophase.
Yes. Chromosomes decondense and lose their identity as discrete elements, so they can no longer be seen individually.
Two daughter nuclei form, one at each pole, each with the same chromosome number as the parent cell (mitosis is equational).
Telophase reassembles the two nuclei (nuclear envelope, nucleolus). Cytokinesis splits the cytoplasm to give two separate cells.
