MCQ
What are X-shaped structures formed due to crossing over called?
✅ Correct Answer: B
Chiasmata are formed during diplotene where crossing over has occurred.
MCQ

MCQ
Why is DNA amount denoted as 2C and 4C across the cell cycle?
✅ Correct Answer: B
2C is the baseline DNA content; after S phase it becomes 4C due to replication.
Assertion-Reason
Assertion (A): Plant cell cytokinesis involves cell wall formation.
Reason (R): In plant cells, wall formation starts from the periphery and grows inward to the centre.
✅ Correct Answer: C
NCERT confirms plant cytokinesis involves wall formation making Assertion true. However, NCERT states “In plant cells, wall formation starts in the centre of the cell and grows outward to meet the existing lateral walls.” The Reason reverses the direction - claiming periphery to centre instead of centre outward. This creates confusion with animal cell furrow formation.
NEET 2025 Pattern
Which of the following statements regarding cytokinesis and syncytium formation are correct?
S1: A syncytium represents a multinucleate condition resulting from karyokinesis without subsequent cytokinesis.
S2: The liquid endosperm of coconut is a notable example of a syncytium in plants.
S3: In animal cells, cytokinesis is accomplished by the formation of a cell plate that expands centrifugally.
S4: Plant cell cytokinesis involves the appearance of a furrow in the plasma membrane, which deepens centripetally.
S5: Organelles such as mitochondria and plastids are typically distributed between daughter cells during cytoplasmic division.
✅ Correct Answer: A
The question tests understanding of cytokinesis mechanisms in plants and animals, and the definition and example of syncytium.
S1: This statement is correct. A syncytium is defined as a multinucleate condition that arises when nuclear division (karyokinesis) is not followed by cytoplasmic division (cytokinesis).
S2: This statement is correct. The liquid endosperm of coconut is explicitly mentioned in NCERT as an example of a syncytium.
S3: This statement is incorrect. In animal cells, cytokinesis occurs through the appearance and deepening of a furrow in the plasma membrane (centripetal), not by the formation of a cell plate. Cell plate formation is characteristic of plant cells.
S4: This statement is incorrect. Plant cells undergo cytokinesis by forming a cell plate in the center, which grows outwards (centrifugally). Furrow formation is characteristic of animal cells.
S5: This statement is correct. During the cytoplasmic division (cytokinesis), organelles like mitochondria and plastids are distributed between the two daughter cells.
Therefore, statements S1, S2, and S5 are correct.
