Show answer & explanation
Correct answer: C — Interphase (G1 → S → G2) followed by Mitosis
The normal sequence for cell growth and division (mitosis) involves the Interphase (G1, S, G2 phases) which prepares the cell, followed by the M phase (Mitosis). G1 initiates growth, S synthesizes DNA, and G2 prepares for division.
Q2. In plant cell development, which event must be successfully completed before the cell transitions from the G2 phase to the M phase (mitosis)?
Show answer & explanation
Correct answer: A — Cell cycle checkpoint satisfaction
Before the cell can enter mitosis (M phase) from G2, all necessary preparatory events, including DNA replication and satisfaction of regulatory checkpoints, must be completed.
Q3. What is the prerequisite stage that must occur before cell differentiation can take place in a plant cell?
Show answer & explanation
Correct answer: B — Cell division
Cell division (mitosis) must occur first to create the necessary cells for subsequent differentiation and growth.
Q4. During the process of plant growth, which stage is characterized by the increase in cell size without an increase in cell number?
Show answer & explanation
Correct answer: C — Cell expansion (enlargement)
Cell expansion (enlargement) is the phase where existing cells increase in volume, contributing to the overall growth of the plant, distinct from cell division.
Q5. What is the role of cell differentiation in the developmental sequence of a plant?
Show answer & explanation
Correct answer: C — To establish specialized cell types like meristem or parenchyma
Differentiation is the process where cells become specialized, which is a prerequisite for organized plant growth and the formation of specific tissues and organs.
Q6. If a plant cell is undergoing continuous growth, the sequence of events involving cell division and expansion usually follows which pattern?
Show answer & explanation
Correct answer: D — Division followed by enlargement
Growth involves both cell division (making new cells) and cell enlargement (increase in size), which happens sequentially.
Q7. The process of cell elongation in plants is closely linked to which phase of the cell cycle?
Show answer & explanation
Correct answer: D — G1 phase
Cell elongation, a key component of growth, occurs primarily during the G1 phase and subsequent growth period before division.
Q8. Which developmental event immediately precedes cell enlargement in a plant cell?
Show answer & explanation
Correct answer: D — DNA replication
Cell enlargement (increase in volume) typically occurs after the cell has completed its preparatory phase, following DNA replication, which precedes the actual mitotic division sequence in growth phases.
Q9. In the process of plant development, which stage follows the cell division and cell expansion phase?
Show answer & explanation
Correct answer: D — Cell differentiation
After cell division and expansion (which occurs primarily in the M phase), the next crucial developmental step is cell differentiation, where cells specialize into different tissues.
Q10. Cell differentiation in plants is largely regulated by the precise control over which developmental processes?
Show answer & explanation
Correct answer: D — Cell growth and division sequence
Plant cell differentiation depends heavily on the sequential execution of growth, division, and subsequent developmental events within the cell cycle.
Q11. Which of the following represents the correct sequential order of major developmental phases occurring during a cell cycle in a plant cell?
Show answer & explanation
Correct answer: D — G1, S, G2, M
The correct sequential order of the phases in the cell cycle is G1 (Gap 1), S (Synthesis), G2 (Gap 2), and M (Mitosis). While Prophase, Metaphase, Anaphase, and Telophase are stages of mitosis, the fundamental cycle progression involves the Interphase (G1, S, G2) followed by the M phase.
Q12. Which process immediately follows cell division in the sequence of plant cell development?
Show answer & explanation
Correct answer: D — Cell enlargement
After cell division (mitosis), the cells typically undergo cell enlargement and subsequent growth to form the complete structure.
Q13. The continuous process of cell growth and enlargement in a plant involves which underlying process?
Show answer & explanation
Correct answer: A — Cell division and enlargement
Plant growth and development is fundamentally driven by cell division (mitosis) followed by the increase in cell volume (enlargement).
Q14. If a plant cell is actively undergoing development, which event must precede the physical cell division?
Show answer & explanation
Correct answer: C — Cell cycle checkpoint satisfaction
For cell division to occur, the cell must successfully complete the necessary checks and signals, ensuring that the developmental programs are properly coordinated before the physical division takes place.
Q15. Which phase in the cell cycle must be successfully completed before a plant cell can enter the phase of cell division?
Show answer & explanation
Correct answer: B — G1 phase
The G1 phase (Gap 1) is the preparatory phase where the cell grows and prepares for DNA synthesis (S phase) before committing to the mitotic division phase (M phase).
