NEET Botany Cell Cycle and Cell Division MCQs

In a plant cell undergoing mitosis, a mutation disrupts the function of phragmoplastin. Which stage of mitosis will be most directly affected, and what would be the observable consequence?

The term 'karyokinesis' refers to the division of the:

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?

Consider the following statements about plant cytokinesis

I. It usually occurs by cell plate method

II. The spindle usually persists during cytokinesis

III. Cell plate grows centrifugally

Which of the statements given above are correct?
