What will you learn in NCERT Class 11 Biology Chapter 10?
In class 11 bio Chapter 10, the students will study the concept of cell cycle and cell division in plant and animal cells, diagrammatic presentation of the changes within the cell during every phases of the cell cycle such as prophase, metaphase, anaphase and telophase, concepts of cytokinesis and karyokinesis, significance of mitosis, meiosis, meiosis i, meiosis ii and significance of meiosis.
The students will also understand the concept of Metaphase that is marked by the alignment of chromosomes at the equatorial plate, Cytokinesis which is the division of the cytoplasm of a cell after Karyokinesis. At the time of Anaphase, the Centromeres divide and the Chromatids begin moving towards the two opposite poles & when the Chromatids reach the two poles, the Chromosomal Elongation begins.

Important Notes On CBSE 11th Biology Chapter 10 Cell Cycle And Cell Division
- Specialised kind of cell division that reduces the chromosomes number by half, hence it is called reductional division.
- Occurs during gametogenesis in plants and animals.
- Involves two sequential cycles of nuclear and cell division called Meiosis I and Meiosis II.
- It results in 4 haploid daughter cells.
- Interphase occurs prior to meiosis which is similar to interphase of mitosis except the S phase is prolonged.
SIGNIFICANCE OF MEIOSIS
- Format ion of gametes: In sexually reproducing organisms.
- Genetic variability: Variations are very important for evolution.
- Maintenance of chromosomal number: By reducing the chromosome number in gametes. Chromosomal number is restored by fertilisation of gametes.
Since the number of chromosomes in the parent and progeny cells is the same, it is called as equational division. Mitosis is divided into four sub stages.
- Replicated chromosomes, each consisting of 2 chromatids, condense and become visible.
- Microtubules are assembled into mitotic spindle.
- Nucleolus and nuclear envelope disappear.
- Centriole moves to opposite poles.
- Spindle fibres attached to kinetochores (small disc-shaped structures at the surface of centromere) of chromosomes.
- Chromosomes line up at the equator of the spindle to form metaphase plate.
- Centromeres split and chromatids separate.
- Chromatids move to opposite poles due to shortening of spindal fibres.
- Chromosomes cluster at opposite poles.
- Nuclear envelope assembles around chromosomes clusters’.
- Nucleolus, Golgi Complex, E.R. reforms.
Significance of Mitosis
- Growth-addition of cells.
- Maintenance of surface/volume ratio. Maintain Nucleo-cytoplasmic ratio.
- Maintenance of chromosomes number.
- Reproduction in unicellular organisms, lower plants and some insects.
- Repair and wound healing.
- Vegetative reproduction in plants takes place by mitosis.
