Bio-Unit7-Plants and Reproduction
| Term | Definition |
|---|---|
| anaphase | a phase of mitosis and meiosis in which the chromosomes separate |
| asexual reproduction | reproduction that does not involve the union of gametes and in which a single parent produces offspring that are genetically identical to the parent |
| autosome | any chromosome that is not a sex chromosome |
| chromosomes | in a eukaryotic cell, one of the structures in the nucleus that are made up of DNA and protein; in a prokaryotic cell, the main ring of DNA |
| cytokinesis | the division of the cytoplasm of a cell; cytokinesis follows the division of the cell's nucleus by mitosis or meiosis |
| interphase | the period of the cell cycle during which activities such as cell growth and protein synthesis occur without visible signs of cell division |
| metaphase | one of the stages of mitosis and meiosis, during which all of the chromosomes move to the cell's equator |
| mitosis | in eukaryotic cells, a process of cell division that forms two new nuclei, each of which has the same number of chromosomes |
| prophase | the first stage of mitosis and meiosis in cell division; characterized by the condensation of the chromosomes |
| sex chromosome | one of the pair of chromosomes that determine the sex of an individual |
| telophase | the final stage of mitosis or meiosis, during which a nuclear membrane forms around each set of new chromosomes |
| plant | multicellular eukaryote that produces its own food through photosynthesis |
| vascular system | collection of specialized tissues in some plants that transports mineral nutrients up from the roots and brings sugars down from the leaves |
| pollination | the transfer of pollen from the male reproductive structures (the anthers) to the tip of the female reproductive strcture (the pistil) of a flower in angiosperms or to the ovule in gymnosperms |
| gymnosperm | a woody, vascular seed plant whose seeds are not enclosed by an ovary or fruit |
| angiosperm | a flowering plant that produces seeds within a fruit |
| cell cycle | pattern of growth, DNA replication, and cell division that occurs in a eukaryotic cell |
| mitosis | in eukaryotic cells, a process of cell division that forms two new nuclei, each of which has the same number of chromosomes |
| homologous chromosome | chromosomes that have the same length, appearance, and copies of genes, although the alleles may differ |
