MCQ Chapter 7 Biology Class 11 Maharashtra Board Cell Division 1. What is the result of cytokinesis-I?Four haploid cellsTwo haploid cellsTwo diploid cellsOne diploid cellQuestion 1 of 202. Why is meiosis-II called homotypic division?It reduces chromosome numberIt is identical to mitosisIt produces diploid cellsIt involves crossing-overQuestion 2 of 203. What happens to the centromere in metaphase-II?It dividesIt disappearsIt elongatesIt moves to the equatorQuestion 3 of 204. What is the final outcome of meiosis-II?Two diploid cellsFour haploid cellsTwo haploid cellsOne diploid cellQuestion 4 of 205. What is the significance of meiosis in maintaining chromosome number?It doubles the chromosome numberIt keeps chromosome number constant across generationsIt eliminates chromosomesIt increases genetic materialQuestion 5 of 206. What provides raw materials for evolution in meiosis?CytokinesisCrossing-overKaryokinesisSpindle fibre formationQuestion 6 of 207. What is synthesized during G1- phase?DNAHistone proteinsRNA and membranesCentriolesQuestion 7 of 208. What appears near the pre-existing centriole pair in G2-phase of animal cells?Spindle fibresA daughter pair of centriolesNuclear membraneChiasmataQuestion 8 of 209.
