Sample questions
-
1.What is the role of the endoplasmic reticulum (ER) in a cell?
- A.It provides structural support and synthesizes proteins and lipids for transport within the cell.
- B.It breaks down waste materials and recycles cellular components through digestion.
- C.It stores genetic information and regulates cell division through chromosome formation.
- D.It generates energy in the form of ATP through cellular respiration processes.
-
2.Assertion: Mitosis maintains the genetic similarity of somatic cells. Reason: Chromosomes do not undergo crossing over. (a) If both assertion and reason are true and reason is the correct explanation of assertion. (b) If both assertion and reason are true, but reason is not the correct explanation of assertion. (c) If assertion is true but reason is false. (d) If both Assertion and Reason are false.
- a.If both assertion and reason are true and reason is the correct explanation of assertion.
- b.If both assertion and reason are true, but reason is not the correct explanation of assertion.
- c.If assertion is true but reason is false.

3.Mitosis is the type of cell division occurring in the cells of injured parts of the body. This statement is:
- A.True
- B.False, it occurs only in reproductive cells
- C.False, it occurs only in plant cells
- D.False, it occurs only during embryonic development
-
4.What is the significance of the cell membrane being semi-permeable?
- A.It allows all substances to freely enter and exit the cell, ensuring rapid exchange of materials.
- B.It selectively permits certain substances to pass while blocking others, regulating solute and ion movement to maintain cellular homeostasis.
- C.It prevents any movement of substances across the membrane, protecting the cell from external harm.
- D.It dissolves unwanted substances inside the cell, ensuring internal cleanliness and balance.
-
5.Which is the shortest phase of mitosis?
- A.Anaphase
- B.Prophase
- C.Metaphase
- D.Telophase
