Grade 10 Life Sciences (Mitosis)

Introduction

Good day students, , Our new topic today is based on Cell Division (Mitosis). Watch this brief video tutorial for more on the topic.

 

 

Task

Please watch both videos before attempting the question.

 

 

 

Question

Mitosis undergo 4 steps, Write an essay and briefly describe what happens in each step and discuss the importance of mitosis.

NB: Your essay must be a maximum of 200 words. (Include word count)

Process

Functions of Mitosis

Following are the two important functions of mitosis:

  1. Mitosis helps in the development of an organism. In single-celled organisms, mitosis is the process of asexual reproduction.
  2. Mitosis helps in the replacement of damaged tissues. The cells near the damaged cells begin mitosis when they do not sense the neighbouring cells. The dividing cells reach each other and cover the damaged cells.

Significance of Mitosis

  1. Mitosis is responsible for the development of the zygote into an adult.
  2. Equal distribution of chromosomes to each daughter cell.
  3. It is responsible for the growth and development of an individual.
  4. It maintains the constant number of chromosomes in all body cells of an organism.
  5. Mitosis is required for asexual reproduction, vegetative propagation in plants and also responsible for repair and regeneration of damaged tissues.
  6. Mitosis helps in maintaining purity of genome as no recombination or crossing over takes place.
  7. It is responsible for repair and regeneration of old and damaged cells in animals e.g. gut epithelium, blood cells, etc.
