Mitosis HSC M5

Which statement is true for mitosis?

• Crossing over occurs during prophase.

• Sister chromatids separate during anaphase.

• Two daughter cells are produced during telophase.

• Homologous pairs of chromosomes line up in metaphase.

Sexual reproduction in plants involves

• pollination caused by dispersal of seeds.

• cloning as it creates copies of the parent plant.

• mitosis leading to the formation of pollen grains

• fertilisation as a result of fusion of male and female gametes.

Which of the following describes the daughter cells produced as a result of mitosis?

• Two genetically different cells

• Two genetically identical cells

• Four genetically different cells

• Four genetically identical cells

Which of the following does NOT play a role in maintaining the health of an organism?

• Mitosis

• Cell death

• Gene expression

• Sexual reproduction

When B cells, a type of white blood cell, are activated they divide to form a large number of antibody-secreting cells. How is this best explained?

• Meiosis and gene expression produce the B cells.

• Meiosis and differentiation produce B cells that repair tissues.

• Mitosis and cell specialisation produce cells that maintain health.

• Mitosis and differentiation produce cells for growth and development.

What does mitosis produce to assist in the maintenance of health?

• Gametes to ensure reproduction

• Polypeptides to ensure cell growth

• Prions to protect cells against cancer

• Cells to replace those that are damaged

Which two processes are important for the maintenance of health?

• Mitosis and meiosis

• Mutation and mitosis

• Mitosis and cell differentiation

• Meiosis and cell differentiation

Here are 3 steps in mitosis:

1. Two sister chromatids move towards opposite ends of the cell.

2. Chromosomes line up in the middle of the cell.

3. Cytokinesis divides the cell into two cells.

Which gives the correct order for mitosis?

• 1, 2, 3

• 1, 3, 2

• 2, 1, 3

• 2, 3, 1

Which statement best describes homologous chromosomes?

• the diploid set of chromosomes

• the haploid set of chromosomes

• all the chromosomes derived from the maternal parent

• chromosomes that carry the same genes at the same location

Which is NOT a similarity between mitosis and meiosis?

• DNA replicates at the start.

• Chromatids separate to opposite poles.

• Duplication of centrosomes.

• Crossing over occurs between chromosomes.
