Cell Division Class 10 Welcome to your Cell Division Class 10 1. The term Meiosis was coined by Flemming Farmer and Moore Winiwarter Strasburger2. New cells need to be produced for All the above Growth Repair and replacement Reproduction3. The regions where crossing over takes place are called Spindle fibres Chromosomes Cell plate Chiasmata4. In meiotic cell division, fo cells are produced by two successive divisions in which ur daughter Both divisions are equational First division is equational and second division is reductional First division is reductional and second division is equational Both divisions are reductional5. Synthesis phase in the cell cycle is called so for the synthesis of more of RNA Glucose RNA and Proteins DNA6. In which one of the following options the stages of mitosis has been given in correct sequence? Telophase,anaphase,prophase,metaphase Anaphase, telophase, prophase, metaphase Prophase, metaphase,telophase,anaphase Prophase, metaphase, anaphase,telophase7. The nuclear membrane and nucleolus become indistinguishable during Prophase Metaphase Telophase Interphase8. The period between two successive mitotic divisions is Anaphase Diakinesis Interphase Mitosis9. Meiosis I is also known as Equational division All of the above Reduction division Direct cell division10. 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 cells11. Karyokinesis is the division of Cell wall Cytoplasm Nucleus Pollen grains12. Duplication of DNA occurs in M - Phase G2 - Phase S - Phase G1 - Phase13. After mitotic cell division, a female human cell will have 22 + Y Chromosome 44 + XY Chromosome 22 + X Chromosome 44 + XX Chromosome14. The nuclear membrane disappears in Zygotene Anaphase Prophase Pachytene15. Meiosis occurs in Vegetative cells Meristematic cells Reproductive cells None of the above16. Duplicated chromosomes are joined at a point termed Chromatid Centromere Centrosome Centriole17. The disappearance of spindle and uncoiling of chromosomes takes place in Telophase Meiosis Anaphase Pachytene18. The centromere divides into two in Metaphase Prophase Telophase Anaphase19. The term chromosome literally means Shining threads Twisted threads Coloured bodies Inherited bodies20. The process of Meiosis takes place to produce Testis and Ovary Sperms and Ova Cells of the brain Cells of the body21. The chromatin material is formed of DNA and Histones DNA only Nucleotides Histones only22. Cell division occurring in somatic cells is Meiosis Diplotene Mitosis Diakinesis23. How many chromosomes are found in a cell of a human? 23 46 20 pairs 46 pairs24. Leptotene, Zygotene and Diplotene phases are found in Prophase and Meiosis I Prophase and Meiosis II Interphase Mitosis25. Cytokinesis is the division of Cell wall Cell Cytoplasm Nucleus26 out of 25Please fill in the comment box below.
