NEET Botany Cell Cycle and Cell Division MCQs

A researcher is studying mitosis in a novel diploid organism with 2n = 16 chromosomes. During metaphase, a drug is applied that inhibits the separation of sister chromatids but allows the cell to progress through anaphase and telophase. At the end of this aberrant cell division, what is the most likely chromosomal composition of the resulting daughter cells?

During meiosis, a hexaploid organism (6n) undergoes a rare mutation where one pair of homologous chromosomes fails to separate during Anaphase I. What will be the ploidy of the resulting gametes?

In a plant species with a diploid number of 12, a mutation causes complete failure of cytokinesis following telophase II of meiosis. What would be the ploidy of the resulting megaspore?

A student observes a plant cell at telophase that lacks a cell plate. This cell has double the chromosome number compared to other cells at telophase. What is the likely outcome of this observation?

During telophase, a plant cell is observed to have twice the number of chromosomes as other cells at the same stage. No cell plate is forming. This suggests a problem with which process, and what is the likely consequence?

If cytokinesis fails during telophase in a plant cell, what would be the observed chromosome number in the resulting cell, and what structure would be missing?

Which stage of cell division is affected if a plant cell has double the expected number of chromosomes and lacks a cell plate, and what is the resulting cellular condition?

A plant cell at telophase contains 48 chromosomes, while other cells at the same stage have 24. No cell plate is observed. What type of cell has likely been formed?
