Cell Division Class 10 Welcome to your Cell Division Class 10 1. The period between two successive mitotic divisions is Mitosis Interphase Diakinesis Anaphase2. Leptotene, Zygotene and Diplotene phases are found in Mitosis Prophase and Meiosis I Interphase Prophase and Meiosis II3. Duplicated chromosomes are joined at a point termed Centrosome Chromatid Centromere Centriole4. How many chromosomes are found in a cell of a human? 23 20 pairs 46 46 pairs5. The nuclear membrane and nucleolus become indistinguishable during Prophase Metaphase Telophase Interphase6. The nuclear membrane disappears in Zygotene Anaphase Prophase Pachytene7. The term chromosome literally means Inherited bodies Twisted threads Coloured bodies Shining threads8. In meiotic cell division, fo cells are produced by two successive divisions in which ur daughter Both divisions are reductional First division is equational and second division is reductional Both divisions are equational First division is reductional and second division is equational9. The centromere divides into two in Prophase Anaphase Metaphase Telophase10. The number of chromosomes are halved in a certain type of cell division which occurs in Only testis All body cells Both testis and ovary Only ovary11. New cells need to be produced for Growth Repair and replacement Reproduction All the above12. The term Meiosis was coined by Strasburger Flemming Farmer and Moore Winiwarter13. The disappearance of spindle and uncoiling of chromosomes takes place in Meiosis Telophase Anaphase Pachytene14. The chromatin material is formed of Histones only Nucleotides DNA only DNA and Histones15. Karyokinesis is the division of Cell wall Cytoplasm Nucleus Pollen grains16. Cytokinesis is the division of Cell wall Nucleus Cell Cytoplasm17. Meiosis occurs in None of the above Vegetative cells Reproductive cells Meristematic cells18. Duplication of DNA occurs in G2 - Phase G1 - Phase M - Phase S - Phase19. After mitotic cell division, a female human cell will have 44 + XX Chromosome 44 + XY Chromosome 22 + Y Chromosome 22 + X Chromosome20. The regions where crossing over takes place are called Chromosomes Chiasmata Cell plate Spindle fibres21. Synthesis phase in the cell cycle is called so for the synthesis of more of Glucose RNA and Proteins DNA RNA22. In which one of the following options the stages of mitosis has been given in correct sequence? Anaphase, telophase, prophase, metaphase Prophase, metaphase,telophase,anaphase Prophase, metaphase, anaphase,telophase Telophase,anaphase,prophase,metaphase23. The process of Meiosis takes place to produce Sperms and Ova Testis and Ovary Cells of the brain Cells of the body24. Cell division occurring in somatic cells is Diplotene Mitosis Diakinesis Meiosis25. Meiosis I is also known as All of the above Reduction division Direct cell division Equational division26 out of 25Please fill in the comment box below.
