Cell Division Class 10 Welcome to your Cell Division Class 10 1. The centromere divides into two in Metaphase Prophase Telophase Anaphase2. The nuclear membrane disappears in Zygotene Anaphase Prophase Pachytene3. How many chromosomes are found in a cell of a human? 20 pairs 23 46 pairs 464. The disappearance of spindle and uncoiling of chromosomes takes place in Telophase Meiosis Pachytene Anaphase5. The number of chromosomes are halved in a certain type of cell division which occurs in Both testis and ovary All body cells Only ovary Only testis6. Duplication of DNA occurs in S - Phase M - Phase G2 - Phase G1 - Phase7. In meiotic cell division, fo cells are produced by two successive divisions in which ur daughter Both divisions are equational Both divisions are reductional First division is equational and second division is reductional First division is reductional and second division is equational8. The nuclear membrane and nucleolus become indistinguishable during Metaphase Interphase Prophase Telophase9. The term chromosome literally means Twisted threads Shining threads Inherited bodies Coloured bodies10. Cell division occurring in somatic cells is Diplotene Diakinesis Meiosis Mitosis11. The term Meiosis was coined by Flemming Strasburger Winiwarter Farmer and Moore12. The chromatin material is formed of Nucleotides Histones only DNA and Histones DNA only13. The process of Meiosis takes place to produce Cells of the brain Testis and Ovary Cells of the body Sperms and Ova14. In which one of the following options the stages of mitosis has been given in correct sequence? Prophase, metaphase,telophase,anaphase Prophase, metaphase, anaphase,telophase Telophase,anaphase,prophase,metaphase Anaphase, telophase, prophase, metaphase15. Karyokinesis is the division of Nucleus Cell wall Cytoplasm Pollen grains16. New cells need to be produced for Growth Reproduction Repair and replacement All the above17. Meiosis occurs in Meristematic cells Reproductive cells None of the above Vegetative cells18. The period between two successive mitotic divisions is Mitosis Diakinesis Anaphase Interphase19. Synthesis phase in the cell cycle is called so for the synthesis of more of RNA DNA RNA and Proteins Glucose20. Meiosis I is also known as All of the above Equational division Reduction division Direct cell division21. After mitotic cell division, a female human cell will have 22 + X Chromosome 22 + Y Chromosome 44 + XY Chromosome 44 + XX Chromosome22. Cytokinesis is the division of Nucleus Cell wall Cytoplasm Cell23. The regions where crossing over takes place are called Chromosomes Cell plate Chiasmata Spindle fibres24. Duplicated chromosomes are joined at a point termed Centrosome Centriole Chromatid Centromere25. Leptotene, Zygotene and Diplotene phases are found in Mitosis Prophase and Meiosis I Interphase Prophase and Meiosis II26 out of 25Please fill in the comment box below.
