Question

Difference between mitosis and meiosis.

Answer 1

hey dear


here is your answer


Difference between Mitosis and meiosis are as follows :-



@ Firstly start from Mitosis @


1) In mitosis DNA has been replicated but chromosome not visible.


2) Each duplicated chromosome have two identical sister chromosome are thicken


3) The chromosome Assemble at the centre means metaphase plate


4) The end of complete set of daughter found In each of pole


5) They are sexual

6) They occur In humans, plants

7) They discover by Oscar hartwig



@ Second meiosis @


1) Each chromosome is replicated and two identical sister called chromatids


2) They are asexual


3) They occur in all organism


4) They consist of two sister chromatids which come as pair.

5) They arranged as pair


6) they align of metaphase plate means (side)


7) they discover by Walter Fleming

8) they have cellular reproduction



hope it helps


thank you

Answer 2

Mitosis is the division of body cells and meiosis is the division of the sex cells.

Explanation:

Mitosis

1) This division takes place in somatic cells and as a result of this growth occurs.  

2) Completed in one stage.

3) Prophase is smaller (when compared to prophase of Meiosis).

4) No crossing over takes place.

5) Synapsis does not take place at metaphase.

6) At metaphase, centromere is towards equatorial plate and ends of chromosomes towards poles. Centromere divides.

7) Chromatids are long and thin.

8) Cytokinesis follows karyokinesis.

Meiosis

1) It takes place in reproductive cells  

2) Completed in two stages.

3) Prophase longer than prophase of mitosis and divided into five substages.

4) Crossing over takes place in which exchange of segments of chromatids occurs.

5) Synapsis between homologous chromosomes takes place (bivalent stage).

6) At metaphase I, the centromere is towards poles and ends of chromosomes towards equatorial plate. Centromere does not divide.

7) Chromatids are shorter and thick  

8) After Telophase I, cytokinesis does not takes place always.
