Lesson Plan of Cell Division
General Science Grade VIII
Students’ learning Outcomes
· Understand procedure of prison theater cellphone division.
· Differentiate betwixt mitoses as well as meiosis.
Information for Teachers
· The partitioning of a prison theater cellphone into 2 immature adult woman cells alongside the similar genetic material.
· Mitosis as well as meiosis are 2 habits that cells reproduce. By mitosis a prison theater cellphone ruptures to create 2 same copies of the master cell. In meiosis cells divided to shape novel cells alongside one-half the usual release of chromosomes, to create gametes for sexual reproduction.
· Process of Mitosis as well as Meiosis.
o The mightiness to reproduce is a characteristic of living things.
o Cellular reproduction is usually referred equally prison theater cellphone partitioning as well as it is a part of the whole life of prison theater cellphone e.g. prison theater cellphone cycle.
· Haploid cells accept i consummate prepare of chromosomes, whereas the term monoploid refers to the release of unique chromosomes inward a biological cell. In diploid organisms, diploid cells comprise the consummate prepare of necessary chromosomes, piece haploid accept alone one-half the release of chromosomes establish inward the nucleus.

Charts of Mitosis as well as Meiosis
Worm upwards action
· Recall the noesis close the prison theater cellphone as well as reproduction.
· Let them intend that why at that topographic point is a involve of prison theater cellphone division?
· Introduce the term prison theater cellphone partitioning past times unproblematic job drawing on the board.
·
· Introduce the 2 types of prison theater cellphone partitioning i.e. Mitosis as well as Meiosis past times drawing.
· Ask why our features resemble alongside our parents as well as siblings.
Development
Activity 1
· Show the students charts of both divisions i past times i or describe it on the board as well as explicate the partitioning on the footing of chromosomes, occurrence as well as importance.
· Inform the students close the haploid as well as diploid cells.
· Ask the students:
o From which type of prison theater cellphone a zygote is developed?
o Ask close the importance of these divisions.
Activity 2
· Ask the students to describe a tabular array on their notebooks as well as write the belike differences betwixt mitosis as well as meiosis.
Mitosis | Meiosis |
Sum upwards / Conclusion
· Conclude the lesson as: prison theater cellphone partitioning is of 2 types; mitosis as well as meiosis. In mitosis 2 diploid immature adult woman cells are formed as well as release of chromosomes remains equally inward raise cell. In meiosis 4 haploid immature adult woman cells as well as release of chromosomes becomes one-half compared to raise cell.
Assessment
· Draw a tabular array on the board to differentiate betwixt mitosis as well as meiosis as well as fill upwards it alongside the assistance of students.
· Ask the students to re-create on their notebooks.
No. | Mitosis | Meiosis | |
1. | Occurrence | ||
2. | Number of Chromosomes | ||
3. | Number of Daughter |
· Ask the next questions to heighten their learning:
o If the raise prison theater cellphone having 24 chromosomes undergoes mitosis hence how many chromosomes volition live acquaint inward immature adult woman cells?
o If at that topographic point is to a greater extent than or less cutting inward your trunk which partitioning heals it?
o The diagram below shows a lizard inward diverse stages of regeneration of its tail.
· What cellular procedure is straight responsible for this regeneration?
a. Meiosis
b. Mitosis
Follow up
· Write the next questions on the board as well as inquire them to re-create as well as solve equally homework on their notebooks.
· Draw a diagram to present a type of prison theater cellphone partitioning which produces immature adult woman cells merely similar the raise cell, equally good advert the diagram.
· Draw a diagram to present a type of prison theater cellphone partitioning which produces immature adult woman cells alongside alone one-half the release of chromosomes equally the raise prison theater cellphone equally good names the diagram.
