(a) the parts labelled 1, 2 and 3.

1 – Centromere

2 – Spindle fibres

3 – Chromatids


The stage described in the diagram is the late anaphase of mitosis in an animal cell. The stage can be identified by the presence of separated chromatids which are found at the two poles of the cell. The appearance of the furrow in the cell membrane classifies the stage as the late anaphase.


The division is mitotic division and this kind of cell division occurs in all the cells of the body except for the reproductive cells.

(d) The stage before anaphase is metaphase

5. The given diagram snows a Stage during mitotic Division in an animal cell:

cell cycle and cell division 2
(a) Identify the stage. Give a reason to support your answer.
(b) Draws neat labeled diagram of the cell as it would appear in the next stage.
(C) In what two ways is mitotic division in an animal cell different from the mitotic division in a plant cell?
(d) Name the type of cell diV1s1on that occurs during :
(i) Growth of a shoot
(ii) Formation of Pollen grains.

(i) Late prophase. The nuclear membrane and nucleolus disappear.

No Mitosis in Plant Cell Mitosis in Animal Cell
1 Asters are not formed. Asters are formed.
2 Occurs at the growing tips. Occurs throughout the body.

A. Mitosis
B: Meiosis

6. Study the diagram given below which represents a during the mitotic cell division and answer the ques that follow :
cell division 3(a) Identity the stage giving suitable reasons.
(b) Name the parts numbered I and 2.
(c) What is the technical term for the division of nucleus?
(d) Mention the stage that comes before the stage shown in the diagram. Draw a neat labelled diagram of the stage mentioned.
(e) Which is the cell division that results in half the number of chromosomes in daughter cells?

(i) Telophase
(ii) 1 – Daughter chromosome, 2 – Nuclear membrane
(iii) Karyokinesis is the technical term for the division of a nucleus.
(iv) Anaphase


(v) Meiosis

7. The diagram given alongside represents a stage during
Cell division 4
Study the same and answer the questions that follow:
(a) Identify whether it is a plant cell or an animal cell. Give a reason in support of your answer.
(b) Name the stage depicted in the diagram. What is the unique feature observed in this stage?
(c) Name the type of cell division that Occur during:
(i) Replacement of old leaves by new ones.
(ii) Formation of gametes.
(d) What is the stage that comes before the stage Show in the diagram?
(e) Draw a neat, labelled diagram of the stage mentioned in (d) above keeping the chromosome number Constant.

a) Animals cell. Because it lacks cell-wall.

b) Metaphase. Chromosomes lined up in one plane at the equator


i). Mitotic cell division

ii)Meiosis (Reductional) cell division

d) Prophase comes before metaphase
