Cell Division

Lesson Plan of Cell Division

General Science Grade VIII

Students’ learning Outcomes

·         Understand process of cell division.
·         Differentiate between mitoses and meiosis.

Information for Teachers

·         The division of a cell into two daughter cells with the similar genetic material.
·         Mitosis and meiosis are two habits that cells reproduce. By mitosis a cell ruptures to create two same copies of the original cell. In meiosis cells divided to form new cells with half the usual number of chromosomes, to produce gametes for sexual reproduction.
Cell Division
·         Process of Mitosis and Meiosis.
o   The ability to reproduce is a characteristic of living things.
o   Cellular reproduction is commonly referred as cell division and it is a part of the whole life of cell e.g. cell cycle.
·         Haploid cells have one complete set of chromosomes, whereas the term monoploid refers to the number of unique chromosomes in a biological cell. In diploid organisms, diploid cells contain the complete set of necessary chromosomes, while haploid have only half the number of chromosomes found in the nucleus.

Charts of Mitosis and Meiosis

Worm up activity

·         Recall the knowledge about the cell and reproduction.
·         Let them think that why there is a need of cell division?
·         Introduce the term cell division by simple line drawing on the board.


·         Introduce the two types of cell division i.e. Mitosis and Meiosis by drawing.
·         Ask why our features resemble with our parents and siblings.


Activity 1

·         Show the students charts of both divisions one by one or draw it on the board and explain the division on the basis of chromosomes, occurrence and importance.
·         Inform the students about the haploid and diploid cells.
·         Ask the students:
o   From which type of cell a zygote is developed?
o   Ask about the importance of these divisions.

Activity 2

·         Ask the students to draw a table on their notebooks and write the probable differences between mitosis and meiosis.

Sum up / Conclusion

·         Conclude the lesson as: cell division is of two types; mitosis and meiosis. In mitosis two diploid daughter cells are formed and number of chromosomes remains as in parent cell. In meiosis four haploid daughter cells and number of chromosomes becomes half compared to parent cell.


·         Draw a table on the board to differentiate between mitosis and meiosis and fill it with the help of students.
·         Ask the students to copy on their notebooks.
Number of Chromosomes
Number of Daughter
·         Ask the following questions to enhance their learning:
o   If the parent cell having 24 chromosomes undergoes mitosis then how many chromosomes will be present in daughter cells?
o   If there is some cut in your body which division heals it?
o   The diagram below shows a lizard in various stages of regeneration of its tail.

·         What cellular process is directly responsible for this regeneration?
a.      Meiosis
b.      Mitosis

Follow up

·         Write the following questions on the board and ask them to copy and solve as homework on their notebooks.
·         Draw a diagram to show a type of cell division which produces daughter cells just like the parent cell, also name the diagram.
·         Draw a diagram to show a type of cell division which produces daughter cells with only half the number of chromosomes as the parent cell also names the diagram.
