Cell Division Class 10 Welcome to your Cell Division Class 10 1. The regions where crossing over takes place are called Cell plate Spindle fibres Chromosomes Chiasmata2. Synthesis phase in the cell cycle is called so for the synthesis of more of DNA RNA and Proteins RNA Glucose3. Cytokinesis is the division of Cell wall Cytoplasm Nucleus Cell4. 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 Both divisions are equational First division is reductional and second division is equational5. The period between two successive mitotic divisions is Anaphase Mitosis Diakinesis Interphase6. The chromatin material is formed of DNA only Histones only DNA and Histones Nucleotides7. Karyokinesis is the division of Pollen grains Nucleus Cytoplasm Cell wall8. The disappearance of spindle and uncoiling of chromosomes takes place in Anaphase Pachytene Meiosis Telophase9. The nuclear membrane disappears in Anaphase Pachytene Zygotene Prophase10. Duplicated chromosomes are joined at a point termed Centriole Centrosome Chromatid Centromere11. Leptotene, Zygotene and Diplotene phases are found in Prophase and Meiosis I Mitosis Prophase and Meiosis II Interphase12. Meiosis occurs in Meristematic cells Reproductive cells None of the above Vegetative cells13. The term Meiosis was coined by Flemming Winiwarter Strasburger Farmer and Moore14. After mitotic cell division, a female human cell will have 22 + X Chromosome 22 + Y Chromosome 44 + XX Chromosome 44 + XY Chromosome15. Duplication of DNA occurs in G2 - Phase G1 - Phase S - Phase M - Phase16. New cells need to be produced for Repair and replacement Reproduction Growth All the above17. The term chromosome literally means Inherited bodies Shining threads Twisted threads Coloured bodies18. The centromere divides into two in Metaphase Anaphase Telophase Prophase19. Cell division occurring in somatic cells is Diplotene Diakinesis Mitosis Meiosis20. Meiosis I is also known as Reduction division All of the above Equational division Direct cell division21. 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 Telophase,anaphase,prophase,metaphase Prophase, metaphase, anaphase,telophase22. The nuclear membrane and nucleolus become indistinguishable during Telophase Metaphase Prophase Interphase23. The process of Meiosis takes place to produce Cells of the brain Testis and Ovary Cells of the body Sperms and Ova24. How many chromosomes are found in a cell of a human? 20 pairs 46 46 pairs 2325. The number of chromosomes are halved in a certain type of cell division which occurs in Only ovary Both testis and ovary Only testis All body cells26 out of 25Please fill in the comment box below.
