Name:_________________________ Cellular Reproduction Vocabulary Date:_________________________ Use Page Numbers! Assignment #_________ Block #____ WORD DEFINITION 1. Cell Cycle The life cycle of a cell Pg 92 2. The structures that DNA is organized into Chromosomes Pg 92 Cellular reproduction in prokaryotic cells. Means “Splitting into two 3. Binary Fission parts” Pg 92 Each chromosome of a pair of similar chromosome 4. Homologous Chromosomes Pg 93 The two copies of the chromosome once it is duplicated 5. Chromatids Pg 93 Where the chromatids are connected 6. Centromere Pg 93 7. Mitosis The complicated process of separating duplicated chromosomes Pg 93 8. Cytokinesis The process where the cytoplasm splits in two Pg 95 WORD DEFINITION 9. Budding A type of asexual reproduction, where a piece of the parents body Pg 612 develops into an independent organism 10. A type of asexual reproduction, where the organism breaks into two or Regeneration more parts, each growing into a new organism that is genetically identical (fragmentation) to the parent Pg 612 The production of offspring by combining the genetic material of more 11. Sexual than one parent reproduction Pg 613 A single parent has offspring that are identical to itself 12. Asexual reproduction Pg 613 The male sex cell 13. Sperm Pg 613 The female sex cell 14. Egg Pg 613 The new type of cell that is made when an egg’s nucleus fuses with a 15. Zygote sperm’s nucleus Pg 613 16. Spores Small reproductive cells that are protected by a thick cell wall Pg 256 WORD DEFINITION 17. Sex Cells Specialized cells that combine to form a zygote, they have half the normal Pg 114 number of chromosomes, one of each pair. 18. Meiosis A process where the chromosomes are copied and separated in such a Pg 115 way that each daughter cell has half the normal number of chromosomes. 19. Sex The chromosomes that carry the genes that determine gender. Chromosomes Pg 119 20. Fertilization The joining of an egg and a sperm Pg 613 21. Cell Plate The primary structure the leads to the new cell membranes between two Pg 95 plant cells during cytokinesis 22. Spindle Fibers that connect to the centromeres of the chromosomes and that Fibers help push and pull the chromosomes apart during mitosis 23. Interphase The cell is at “rest” Chromosomes and other cell materials are copied 24. Prophase First stage of mitosis, nuclear membrane breaks apart, the centrioles move to opposite sides of the cell WORD DEFINITION 25. Metaphase Second phase of mitosis, the chromosomes line up along the equator of the cell 26. Anaphase Third phase of mitosis, the chromatids separate and are pulled to oppo- site sides of the cell 27. Telophase Forth and final phase of mitosis, nuclear membranes reform around the chromosomes and they unwind. .
