Term | Definition |
---|---|
Life Cycle of a Cell | Interphase, Mitosis, Cytokinesis |
Ways Organisms Reproduce Asexually | Binary Fission Budding Spores, Vegetative Reproduction |
Phases of Mitosis | Prophase, Metaphase, Anaphase, Telophase |
DNA | deoxyribonucleic acid, a molecule that is present in all living cells and that contains the information that determines the traits that a living thing inherits and needs to live |
Chromosomes | in a eukaryotic cell, one of the structures in the nucleus that are made up of DNA and protein; in a prokeryotic cell, the main ring of DNA |
Cell Cycle | the life of a cell |
Interphase | the period of a cell cycle during which activities such as cell growth and protein synthesis occur without visual signs of cell division |
Mitosis | in eukaryotic cells, a process of cell division that forms two new nuclei, each of which has the same number of chromosomes |
Cytokinesis | the division of the cytoplasm of a cell |
Homologous Chromosomes | chromosomes that have the same sequence of genes and the same structure |
Meiosis | a process in cell division during which the number of chromosomes decreases to half the original number by two divisions of the nucleus, which results in the production of sex cells (gametes or spores) |
Asexual Reproduction | reproduction that does not involve the union of sex cells and in which one parent produces offspring that are genetically identical to the parent |
Sexual Reproduction | reproduction in which the sex cells from two parents unite to produce offspring that share traits from both parents |
Fertilization | the union of a male and female gamete to form a zygote |
