Cell Cycle and Cell Division Assertion and Reason Questions for NEET
In each of the following questions, a statement of Assertion (A) is given and a corresponding statement of Reason (R) is given just below it. Of the statements, pick the correct answer as :
Assertion : Meiosis introduces new combination of traits in the progeny. Reason : Meiosis involves crossing over
Assertion : During metaphase, the chromosomes align at equatorial plate. Reason : Total number of chromosomes can be observed during metaphase.
Assertion : The colchicine treated meristematic cells show doubling of chromosomes. Reason : Colchicine does not inhibit chromosome replication
Assertion : Chiasmata is observed in the zygotene stage. Reason : Chiasmata is a X-shaped structure
Assertion : In animal cells, the poles are formed by the asters. Reason : They are called amphiaster, since two asters are present at the spindle of animal cells.
Assertion : Cell division occurs only in asexually reproducing organisms. Reason : A typical eukaryotic cell divides once in 24 hours.
Assertion : The mitotic division is called equational division. Reason : The second meiotic division is also homotypic or equational division
Assertion : Interkinesis is a stage between two meiotic divisions. Reason : Interkinesis is generally short lived.
Cell Cycle and Cell Division Figure-Based Questions for NEET
Refer to the given figure and answer the following question.
(a) What do the figures represent? Also identify the stages P, Q, R and S from the given figure.
A. The figures represent the stages of meiosis II. Here, P – Prophase II, Q – Metaphase II, R – Anaphase II S – Telophase II.
(b) What major changes occur in the given figure S?
A. During telophase II is figure, following changes occur:
(i) the groups of chromosomes arrange themselves into haploid nuclei
(ii) nucleolus is formed
(iii) nucleoplasm and nuclear envelope appears
(iv) chromosomes elongate to form chromatin.
(c) How does this figure differ from mitosis?
A. The given figure represents the stages of meiosis II. It differs from mitosis in following ways :
(i) It always occurs in haploid cells.
(ii) It is not preceded by DNA replication.
(iii) The two chromatids of a chromosome are often dissimilar.
(iv) The daughter cells formed after meiosis II are neither similar to each other nor similar to the parent cell.
