Chapter 5: Cellular Processes — Online MCQ Test

Q: Which phase of the cell cycle is the period of actual cell growth before DNA replication?

Answer: A. G1 phase — The G1 phase is the first gap phase in which the cell grows and performs normal metabolic activities before DNA synthesis begins.

Q: Which process results in the formation of two genetically identical daughter cells?

Answer: B. Mitosis — Mitosis produces two daughter cells that are genetically identical to the parent cell, maintaining the chromosome number.

Q: During which stage of mitosis do chromosomes align at the equator of the cell?

Answer: B. Metaphase — In metaphase, chromosomes arrange themselves along the equatorial plane, forming the metaphase plate.

Q: A cell has 46 chromosomes before meiosis begins. How many chromosomes will each daughter cell have after meiosis II?

Answer: B. 23 — Meiosis reduces the chromosome number by half, so a diploid cell with 46 chromosomes produces haploid cells with 23 chromosomes each.

Chapter 5: Cellular Processes — Important Questions & Answers (FAQ)

Frequently asked questions from CBSE(NCERT) Grade 11 BIOTECHNOLOGY — Chapter 5: Cellular Processes, with answers and explanations. These are sample questions; the exam has its own separate question set.

Which phase of the cell cycle is the period of actual cell growth before DNA replication?

A. G1 phase ✓
B. S phase
C. G2 phase
D. M phase

Answer: A. G1 phase
The G1 phase is the first gap phase in which the cell grows and performs normal metabolic activities before DNA synthesis begins.

Which process results in the formation of two genetically identical daughter cells?

A. Meiosis
B. Mitosis ✓
C. Fertilization
D. Crossing over

Answer: B. Mitosis
Mitosis produces two daughter cells that are genetically identical to the parent cell, maintaining the chromosome number.

During which stage of mitosis do chromosomes align at the equator of the cell?

A. Prophase
B. Metaphase ✓
C. Anaphase
D. Telophase

Answer: B. Metaphase
In metaphase, chromosomes arrange themselves along the equatorial plane, forming the metaphase plate.

Which of the following events occurs in anaphase of mitosis?

A. Chromosomes line up at the equator
B. Sister chromatids separate and move to opposite poles ✓
C. Chromatin condenses into chromosomes
D. Nuclear membrane reappears

Answer: B. Sister chromatids separate and move to opposite poles
In anaphase, the centromeres split and sister chromatids are pulled to opposite poles of the cell.

A cell has 46 chromosomes before meiosis begins. How many chromosomes will each daughter cell have after meiosis II?

A. 46
B. 23 ✓
C. 92
D. 12

Answer: B. 23
Meiosis reduces the chromosome number by half, so a diploid cell with 46 chromosomes produces haploid cells with 23 chromosomes each.
