AIIMS Botany Cell Cycle Cell Division Class 11 Questions

Interphase divides into

In the somatic cell cycle

Assertion: Meiotic division results in the production of haploid cells. Reason : Synapsis occurs during zygotene of meiosis.

Each of these questions contains two statements. Assertion (A) and Reason (R). Each of these questions also has four alternative choices, only one of which is the correct answer. You have to select one of the codes (a), (b), (c) and (d) given below. Assertion (A) G⁻phase is also called anaphase, as during this phase the cell stores ATP for cell division. Reason (R) Cell produces structural and functional proteins. Cell’s metabolic rate is high and is controlled by the enzymes.
