Across
- 1. Visual arrangement of chromosomes
- 4. a method of asexual reproduction where a single organism divides into two organisms.
- 6. a mode of reproduction in which a single parent produces a new offspring
- 9. a type of cell division that results in four daughter cells each with half the number of chromosomes of the parent cell, as in the production of gametes
- 10. a network of filaments that are formed during the cell division process
- 13. the second stage of cell division, between prophase and anaphase, during which the chromosomes become attached to the spindle fibers.
- 15. Process of sperm cell development in the testes.
- 17. the process by which a cell replicates its chromosomes and then segregates them, producing two identical nuclei in preparation for cell division
- 18. the stage of meiotic or mitotic cell division in which the chromosomes move away from one another
- 19. Exchange of genetic material between homologous chromosomes.
Down
- 2. the first stage of cell division, before metaphase, during which the chromosomes become visible as paired chromatids and the nuclear envelope disappears
- 3. the cytoplasmic division of a cell at the end of mitosis or meiosis, bringing about the separation into two daughter cells
- 5. The process by which genetic material is exchanged between different organisms.
- 7. dividing plant cell that eventually forms the middle lamella of the wall between the daughter cells.
- 8. the final phase of cell division, between anaphase and interphase
- 11. Leads to the physical separation of the two daughter cells.
- 12. the resting phase between successive mitotic divisions of a cell, or between the first and second divisions of meiosis.
- 14. process of egg cell development in the ovaries.
- 16. a reproductive cell of an animal or plant
