Cell Division Class 10 Welcome to your Cell Division Class 10 1. The disappearance of spindle and uncoiling of chromosomes takes place in Telophase Meiosis Anaphase Pachytene2. The period between two successive mitotic divisions is Mitosis Interphase Anaphase Diakinesis3. The regions where crossing over takes place are called Cell plate Spindle fibres Chiasmata Chromosomes4. Meiosis occurs in Vegetative cells Meristematic cells None of the above Reproductive cells5. In meiotic cell division, fo cells are produced by two successive divisions in which ur daughter First division is equational and second division is reductional Both divisions are reductional First division is reductional and second division is equational Both divisions are equational6. Duplicated chromosomes are joined at a point termed Chromatid Centriole Centromere Centrosome7. The process of Meiosis takes place to produce Sperms and Ova Cells of the brain Cells of the body Testis and Ovary8. Cytokinesis is the division of Cell wall Nucleus Cytoplasm Cell9. The number of chromosomes are halved in a certain type of cell division which occurs in All body cells Both testis and ovary Only testis Only ovary10. How many chromosomes are found in a cell of a human? 46 23 20 pairs 46 pairs11. Duplication of DNA occurs in M - Phase S - Phase G1 - Phase G2 - Phase12. The nuclear membrane and nucleolus become indistinguishable during Interphase Prophase Metaphase Telophase13. The nuclear membrane disappears in Zygotene Prophase Anaphase Pachytene14. The term Meiosis was coined by Farmer and Moore Winiwarter Flemming Strasburger15. Cell division occurring in somatic cells is Diakinesis Mitosis Diplotene Meiosis16. The term chromosome literally means Inherited bodies Twisted threads Coloured bodies Shining threads17. Meiosis I is also known as Direct cell division All of the above Equational division Reduction division18. Leptotene, Zygotene and Diplotene phases are found in Prophase and Meiosis II Mitosis Interphase Prophase and Meiosis I19. In which one of the following options the stages of mitosis has been given in correct sequence? Prophase, metaphase, anaphase,telophase Telophase,anaphase,prophase,metaphase Anaphase, telophase, prophase, metaphase Prophase, metaphase,telophase,anaphase20. The chromatin material is formed of DNA only Nucleotides DNA and Histones Histones only21. New cells need to be produced for All the above Reproduction Growth Repair and replacement22. Karyokinesis is the division of Pollen grains Cytoplasm Nucleus Cell wall23. Synthesis phase in the cell cycle is called so for the synthesis of more of RNA Glucose RNA and Proteins DNA24. The centromere divides into two in Metaphase Anaphase Telophase Prophase25. After mitotic cell division, a female human cell will have 44 + XX Chromosome 22 + X Chromosome 22 + Y Chromosome 44 + XY Chromosome26 out of 25Please fill in the comment box below.
