Cell Division Class 10 Welcome to your Cell Division Class 10 1. New cells need to be produced for Growth All the above Repair and replacement Reproduction2. Meiosis occurs in Vegetative cells Meristematic cells Reproductive cells None of the above3. Cytokinesis is the division of Cell wall Cytoplasm Nucleus Cell4. Karyokinesis is the division of Pollen grains Cell wall Cytoplasm Nucleus5. Duplicated chromosomes are joined at a point termed Centrosome Chromatid Centromere Centriole6. Leptotene, Zygotene and Diplotene phases are found in Prophase and Meiosis II Interphase Mitosis Prophase and Meiosis I7. The number of chromosomes are halved in a certain type of cell division which occurs in Only ovary Only testis All body cells Both testis and ovary8. In which one of the following options the stages of mitosis has been given in correct sequence? Anaphase, telophase, prophase, metaphase Prophase, metaphase, anaphase,telophase Telophase,anaphase,prophase,metaphase Prophase, metaphase,telophase,anaphase9. After mitotic cell division, a female human cell will have 44 + XX Chromosome 22 + X Chromosome 44 + XY Chromosome 22 + Y Chromosome10. The term Meiosis was coined by Farmer and Moore Strasburger Flemming Winiwarter11. The regions where crossing over takes place are called Cell plate Chiasmata Chromosomes Spindle fibres12. The nuclear membrane disappears in Anaphase Zygotene Prophase Pachytene13. The nuclear membrane and nucleolus become indistinguishable during Prophase Metaphase Telophase Interphase14. Duplication of DNA occurs in G2 - Phase M - Phase G1 - Phase S - Phase15. Meiosis I is also known as Reduction division Equational division Direct cell division All of the above16. The period between two successive mitotic divisions is Diakinesis Anaphase Interphase Mitosis17. 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 First division is equational and second division is reductional Both divisions are equational Both divisions are reductional18. The term chromosome literally means Inherited bodies Coloured bodies Twisted threads Shining threads19. How many chromosomes are found in a cell of a human? 46 23 20 pairs 46 pairs20. The centromere divides into two in Metaphase Prophase Telophase Anaphase21. Cell division occurring in somatic cells is Mitosis Meiosis Diakinesis Diplotene22. Synthesis phase in the cell cycle is called so for the synthesis of more of RNA RNA and Proteins Glucose DNA23. The process of Meiosis takes place to produce Cells of the brain Sperms and Ova Testis and Ovary Cells of the body24. The chromatin material is formed of DNA only Nucleotides DNA and Histones Histones only25. The disappearance of spindle and uncoiling of chromosomes takes place in Pachytene Telophase Meiosis Anaphase26 out of 25Please fill in the comment box below.
