Questions with solutions
Q1 — Cell Division (Mitosis/Meiosis) · medium · theory
The type of cell division that produces two identical daughter cells for growth and repair is:
A. meiosis
B. budding
C. mitosis ✓ Correct
D. fission only
Solution: Mitosis produces two genetically identical daughter cells, used for growth and repair.
Q2 — Cell Division (Mitosis/Meiosis) · hard · theory
The type of cell division that produces four cells with half the chromosome number, used to form gametes, is:
A. regeneration
B. meiosis ✓ Correct
C. mitosis
D. binary fission
Solution: Meiosis is a reduction division producing four cells with half the chromosomes (gametes).
Q3 — Cell Division (Mitosis/Meiosis) · medium · theory
Mitosis keeps the chromosome number of daughter cells:
A. zero
B. half of the parent cell
C. the same as the parent cell ✓ Correct
D. double the parent cell
Solution: Mitosis conserves the chromosome number, giving each daughter cell the same number as the parent.
Q4 — Cell Division (Mitosis/Meiosis) · hard · theory
Meiosis is called a reduction division because it:
A. keeps the number the same
B. removes the nucleus
C. halves the chromosome number ✓ Correct
D. doubles the chromosome number
Solution: Meiosis reduces the chromosome number to half, which is restored at fertilisation.
Q5 — Cell Division (Mitosis/Meiosis) · medium · theory
Mitosis mainly occurs in the ______ cells of the body:
A. dead
B. bacterial
C. reproductive (gamete)
D. somatic (body) ✓ Correct
Solution: Mitosis takes place in body (somatic) cells for growth and repair.
Q6 — Cell Division (Mitosis/Meiosis) · hard · theory
Meiosis takes place in the ______ organs to produce gametes:
A. excretory
B. digestive
C. reproductive ✓ Correct
D. respiratory
Solution: Meiosis occurs in reproductive organs to form sex cells (gametes).
Q7 — Cell Division (Mitosis/Meiosis) · easy · theory
One round of mitosis produces how many daughter cells from a single parent cell?
A. 2 ✓ Correct
B. 8
C. 1
D. 4
Solution: Mitosis divides one parent cell into 2 daughter cells that are genetically identical to it.
Q8 — Cell Division (Mitosis/Meiosis) · medium · numerical
A human body (somatic) cell has 46 chromosomes. How many chromosomes will EACH daughter cell have after mitosis?
A. 23
B. 92
C. 46 ✓ Correct
D. 12
Solution: Mitosis is an equational division: each daughter cell receives the same chromosome number as the parent, so 46 chromosomes.
Q9 — Cell Division (Mitosis/Meiosis) · hard · numerical
A cell with 46 chromosomes undergoes meiosis. How many chromosomes will be present in each resulting cell, and how many cells are formed?
A. 46 chromosomes in each of 2 cells
B. 23 chromosomes in each of 4 cells ✓ Correct
C. 46 chromosomes in each of 4 cells
D. 23 chromosomes in each of 2 cells
Solution: Meiosis halves the chromosome number and involves two successive divisions, so it produces 4 cells, each with 23 chromosomes (the haploid number).
Q10 — Cell Division (Mitosis/Meiosis) · hard · theory
Assertion: Meiosis is essential for sexual reproduction. Reason: By halving the chromosome number in gametes, meiosis lets fertilisation restore the original number in the offspring. Choose the correct option.
A. Both the assertion and the reason are true, and the reason correctly explains the assertion ✓ Correct
B. Both the assertion and the reason are false
C. The assertion is true but the reason is false
D. Both are true, but the reason does not explain the assertion
Solution: If gametes were not halved, the chromosome number would double every generation. Meiosis halves it and fertilisation then combines two gametes to restore the original number, so the reason explains the assertion.
