Cell Division Class 10 Welcome to your Cell Division Class 10 1. The period between two successive mitotic divisions is Mitosis Anaphase Diakinesis Interphase2. After mitotic cell division, a female human cell will have 44 + XY Chromosome 22 + X Chromosome 22 + Y Chromosome 44 + XX Chromosome3. The term Meiosis was coined by Winiwarter Strasburger Farmer and Moore Flemming4. The centromere divides into two in Anaphase Metaphase Prophase Telophase5. Duplicated chromosomes are joined at a point termed Centriole Centrosome Chromatid Centromere6. The regions where crossing over takes place are called Spindle fibres Chromosomes Cell plate Chiasmata7. Meiosis I is also known as Equational division All of the above Reduction division Direct cell division8. Cell division occurring in somatic cells is Meiosis Diplotene Diakinesis Mitosis9. The term chromosome literally means Shining threads Twisted threads Inherited bodies Coloured bodies10. The nuclear membrane disappears in Prophase Pachytene Zygotene Anaphase11. How many chromosomes are found in a cell of a human? 23 46 20 pairs 46 pairs12. Meiosis occurs in Meristematic cells Vegetative cells None of the above Reproductive cells13. The chromatin material is formed of DNA only DNA and Histones Nucleotides Histones only14. The nuclear membrane and nucleolus become indistinguishable during Prophase Interphase Telophase Metaphase15. In meiotic cell division, fo cells are produced by two successive divisions in which ur daughter First division is reductional and second division is equational Both divisions are reductional First division is equational and second division is reductional Both divisions are equational16. The disappearance of spindle and uncoiling of chromosomes takes place in Telophase Pachytene Meiosis Anaphase17. New cells need to be produced for Repair and replacement Reproduction All the above Growth18. The process of Meiosis takes place to produce Cells of the brain Sperms and Ova Testis and Ovary Cells of the body19. Leptotene, Zygotene and Diplotene phases are found in Prophase and Meiosis II Interphase Prophase and Meiosis I Mitosis20. The number of chromosomes are halved in a certain type of cell division which occurs in Both testis and ovary Only testis Only ovary All body cells21. In which one of the following options the stages of mitosis has been given in correct sequence? Prophase, metaphase, anaphase,telophase Anaphase, telophase, prophase, metaphase Telophase,anaphase,prophase,metaphase Prophase, metaphase,telophase,anaphase22. Karyokinesis is the division of Pollen grains Nucleus Cytoplasm Cell wall23. Cytokinesis is the division of Cytoplasm Nucleus Cell wall Cell24. Duplication of DNA occurs in M - Phase S - Phase G1 - Phase G2 - Phase25. Synthesis phase in the cell cycle is called so for the synthesis of more of Glucose RNA DNA RNA and Proteins26 out of 25Please fill in the comment box below.
