Cell Division Class 10 Welcome to your Cell Division Class 10 1. Synthesis phase in the cell cycle is called so for the synthesis of more of DNA Glucose RNA RNA and Proteins2. Cytokinesis is the division of Cytoplasm Nucleus Cell wall Cell3. How many chromosomes are found in a cell of a human? 46 20 pairs 23 46 pairs4. The centromere divides into two in Telophase Anaphase Prophase Metaphase5. Cell division occurring in somatic cells is Diplotene Mitosis Meiosis Diakinesis6. The process of Meiosis takes place to produce Cells of the brain Testis and Ovary Cells of the body Sperms and Ova7. The disappearance of spindle and uncoiling of chromosomes takes place in Pachytene Meiosis Anaphase Telophase8. 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 equational Both divisions are reductional First division is reductional and second division is equational9. The regions where crossing over takes place are called Spindle fibres Cell plate Chromosomes Chiasmata10. The term chromosome literally means Coloured bodies Twisted threads Shining threads Inherited bodies11. After mitotic cell division, a female human cell will have 44 + XY Chromosome 44 + XX Chromosome 22 + Y Chromosome 22 + X Chromosome12. The period between two successive mitotic divisions is Interphase Anaphase Diakinesis Mitosis13. Meiosis occurs in Vegetative cells Meristematic cells None of the above Reproductive cells14. Leptotene, Zygotene and Diplotene phases are found in Prophase and Meiosis II Interphase Prophase and Meiosis I Mitosis15. Duplication of DNA occurs in S - Phase M - Phase G2 - Phase G1 - Phase16. In which one of the following options the stages of mitosis has been given in correct sequence? Prophase, metaphase, anaphase,telophase Prophase, metaphase,telophase,anaphase Anaphase, telophase, prophase, metaphase Telophase,anaphase,prophase,metaphase17. 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 cells18. Meiosis I is also known as Direct cell division Reduction division All of the above Equational division19. The term Meiosis was coined by Farmer and Moore Flemming Winiwarter Strasburger20. Duplicated chromosomes are joined at a point termed Chromatid Centromere Centrosome Centriole21. Karyokinesis is the division of Cell wall Cytoplasm Nucleus Pollen grains22. The nuclear membrane and nucleolus become indistinguishable during Interphase Prophase Telophase Metaphase23. The nuclear membrane disappears in Anaphase Zygotene Pachytene Prophase24. The chromatin material is formed of Nucleotides Histones only DNA and Histones DNA only25. New cells need to be produced for Growth Repair and replacement Reproduction All the above26 out of 25Please fill in the comment box below.
