Cell Division Class 10 Welcome to your Cell Division Class 10 1. Duplicated chromosomes are joined at a point termed Centrosome Chromatid Centriole Centromere2. 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,anaphase3. The disappearance of spindle and uncoiling of chromosomes takes place in Anaphase Pachytene Meiosis Telophase4. The term Meiosis was coined by Winiwarter Flemming Farmer and Moore Strasburger5. Cell division occurring in somatic cells is Diakinesis Mitosis Diplotene Meiosis6. After mitotic cell division, a female human cell will have 22 + X Chromosome 44 + XX Chromosome 22 + Y Chromosome 44 + XY Chromosome7. Leptotene, Zygotene and Diplotene phases are found in Interphase Prophase and Meiosis I Mitosis Prophase and Meiosis II8. The chromatin material is formed of Histones only DNA only Nucleotides DNA and Histones9. The period between two successive mitotic divisions is Interphase Anaphase Diakinesis Mitosis10. Meiosis occurs in Vegetative cells Reproductive cells None of the above Meristematic cells11. In meiotic cell division, fo cells are produced by two successive divisions in which ur daughter Both divisions are reductional First division is reductional and second division is equational Both divisions are equational First division is equational and second division is reductional12. The centromere divides into two in Telophase Anaphase Metaphase Prophase13. The number of chromosomes are halved in a certain type of cell division which occurs in Only testis Both testis and ovary Only ovary All body cells14. The process of Meiosis takes place to produce Sperms and Ova Cells of the brain Cells of the body Testis and Ovary15. Meiosis I is also known as Reduction division Direct cell division All of the above Equational division16. Duplication of DNA occurs in G1 - Phase G2 - Phase M - Phase S - Phase17. The nuclear membrane and nucleolus become indistinguishable during Prophase Interphase Telophase Metaphase18. The nuclear membrane disappears in Pachytene Anaphase Zygotene Prophase19. How many chromosomes are found in a cell of a human? 46 23 20 pairs 46 pairs20. New cells need to be produced for All the above Reproduction Repair and replacement Growth21. Cytokinesis is the division of Cell wall Cell Cytoplasm Nucleus22. The term chromosome literally means Coloured bodies Twisted threads Shining threads Inherited bodies23. The regions where crossing over takes place are called Cell plate Spindle fibres Chiasmata Chromosomes24. Karyokinesis is the division of Cell wall Nucleus Pollen grains Cytoplasm25. Synthesis phase in the cell cycle is called so for the synthesis of more of DNA Glucose RNA RNA and Proteins26 out of 25Please fill in the comment box below.
