Cell Division Class 10 Welcome to your Cell Division Class 10 1. Cytokinesis is the division of Cytoplasm Cell wall Nucleus Cell2. The chromatin material is formed of Nucleotides DNA and Histones DNA only Histones only3. The period between two successive mitotic divisions is Mitosis Diakinesis Anaphase Interphase4. Meiosis I is also known as Reduction division All of the above Direct cell division Equational division5. The regions where crossing over takes place are called Spindle fibres Chromosomes Chiasmata Cell plate6. Cell division occurring in somatic cells is Meiosis Diplotene Mitosis Diakinesis7. After mitotic cell division, a female human cell will have 44 + XX Chromosome 22 + X Chromosome 22 + Y Chromosome 44 + XY Chromosome8. 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 First division is reductional and second division is equational Both divisions are reductional Both divisions are equational9. The process of Meiosis takes place to produce Cells of the body Sperms and Ova Cells of the brain Testis and Ovary10. Meiosis occurs in Meristematic cells Vegetative cells Reproductive cells None of the above11. The centromere divides into two in Anaphase Telophase Metaphase Prophase12. The number of chromosomes are halved in a certain type of cell division which occurs in Only ovary Only testis Both testis and ovary All body cells13. In which one of the following options the stages of mitosis has been given in correct sequence? Prophase, metaphase,telophase,anaphase Prophase, metaphase, anaphase,telophase Telophase,anaphase,prophase,metaphase Anaphase, telophase, prophase, metaphase14. The nuclear membrane disappears in Zygotene Anaphase Prophase Pachytene15. The disappearance of spindle and uncoiling of chromosomes takes place in Pachytene Meiosis Telophase Anaphase16. Synthesis phase in the cell cycle is called so for the synthesis of more of DNA RNA Glucose RNA and Proteins17. New cells need to be produced for Repair and replacement Growth Reproduction All the above18. Duplicated chromosomes are joined at a point termed Centrosome Centromere Chromatid Centriole19. Karyokinesis is the division of Pollen grains Nucleus Cytoplasm Cell wall20. The nuclear membrane and nucleolus become indistinguishable during Interphase Prophase Metaphase Telophase21. How many chromosomes are found in a cell of a human? 20 pairs 46 pairs 23 4622. Leptotene, Zygotene and Diplotene phases are found in Mitosis Interphase Prophase and Meiosis II Prophase and Meiosis I23. Duplication of DNA occurs in G1 - Phase G2 - Phase S - Phase M - Phase24. The term Meiosis was coined by Flemming Farmer and Moore Strasburger Winiwarter25. The term chromosome literally means Twisted threads Coloured bodies Inherited bodies Shining threads26 out of 25Please fill in the comment box below.
