Solution

1) Repeating pattern of cell growth and division. Interphase ( the period between cell divisions) consists of G1, S( the time of chromosome replication ) and G2 . The cells divide during M phase , and the daughter cells separate from each other through cytokinesis at the end of M phase.

Ans : Cell Cycle

2)Strutures found at centromeres that connect the chromosome to the microtubule fibre of the spindle

Ans : Kinetochores

At the beginning of nuclear division, two wheel-shaped protein structures called centrioles position themselves at opposite ends of the cell forming cell poles. Long protein fibers called microtubules extend from the centrioles in all possible directions, forming what is called a spindle. Some of the microtubules attach the poles to the chromosomes by connecting to protein complexes called kinetochores. Kinetochores are protein formations that develop on each chromosome around the centromere, which is a region located near the middle of a chromosome.

3) cell division that preserves the number and kinds of chromosome. Successive rounds of this type of cellular division starting from fertilized zygotecreate a multi-cellular organism whose somatic cells are genetically identical

Ans : Mitosis

4) germ line cells in the ovaries that undergo meiosis –

Ans: Oocytes

      germ line cells in the testes that undergo meiosis -

Ans : Spermatocyte

5)   secondary oocyte that undergo meiosis II

Ans : It forms an ootid and a polar body

     secondary spermatocyte cells that undergo meiosis II

Ans: It form two spermatids
