1-4: The image shows a cell in two stages of cell division:

cell division 1

This type of cell division can be found all over the body, but not in the sex organs.

 
1. Which statement about this type of cell division is untrue ?
  • A. It is called mitosis
  • B. It is involved in asexual reproduction
  • C. It is called meiosis
  • D. It is involved in the growth of an organism
2. Where in plants is this type of cell division is found?
  • A. In the petals of flowers
  • B. In a mature leaf
  • C. In the ends of roots
  • D. In the xylem vessels
3. What is structure X in the diagram above?
  • A. nucleus
  • B. cytoplasm
  • C. mitochondria
  • D. chromosome

4. In this type of cell division, which statement below is NOT true?

  • A. The genetic material in the daughter cells is identical to that in the parent cell
  • B. The number of chromosomes in the daughter cell is the same as in the parent cell
  • C. Four cells are produced
  • D. Two cells are produced

5. Sexual reproduction involves the production of gametes and a different type of cell division. Some of the stages of this type of cell division are shown in the diagram.

Which statement about this type of cell division is untrue?

  • A. The daughter cells are identical to the parent cell
  • B. It occurs in the reproductive organs of plants and animals
  • C. It is called meiosis
  • D. The genetic material in the daughter cells is different to that in the parent cell

  2. Takes a long time
  3. Is a relatively quick process
  4. 2 daughter cells are formed
  5. 4 daughter cells are formed
  6. Chromosome number in daughter cells is half that of parent cell
  7. Chromosome number in the daughter cells is the same as parent cell
  
6. The statements describing mitosis are ..
  • A. 1, 2, 4, 6.
  • B. 1, 3, 5, 7.
  • C. 1, 3, 4, 7.
