| Term | Definition |
|---|
| mitosis | division of the cell nucleus that occurs in eukaryotic cells |
| cytokinesis | division of the cytoplasm that occurs in eukaryotic cells |
| interphase | chromosomes are replicated; chromosomes exsist as chromatin; resting phase |
| prophase | centrioloes begin to seperate and are connected by spindle fibers; chromosomes can now be seen; nucleus bgins to breakdown and disappear |
| metaphase | centrioles move to opposite poles; doubled chromosomes connected by centromeres move to the center of the cell along a spindle fiber |
| anaphase | chromatids seperate and move to opposite poles of the cell; centromeres replicate; late anaphase-cytoplasmic division begins |
| telophase | two mew nuclei form; nuclear membrane reforms around cells' centrioles replicate in late telophase |
| runners | long slender stem that grows along the surface of the ground |
| corm | type of bulb, short underground stem that stores food for the plant |
| bulb | specialized underground stem, surrounded by thick fleshy leaves, that stores food for new plant growth |
| vegetative propagation | the process in which undifferentiated plant cells divide mitotically and then differentiate to produce a new plant |
| plantlet | small plant on the end of a runner that will grow as a new plant |
| rhizome | undergroung stem that grows horizontally through the soil and stores food for the plant |
| tuber | enlarged part of an underground stem that grows in an irregular shape and stores food for the plant |
| cutting | part of stem root or leaf being removed to produce a new individual; grower cuts stem with buds containing meristematic tissue to produce a new plant |
| layering | the plant is still connected to its mother yet in continues to grow on its own |
| grafting | a stem or bud is removed from one plant and joined with a closely related plant |
| scion | bud used in the process of grafting |
| stock | part of the plant the scion attaches to, in grafting |
| budding | nucleus moves to one side of the cell then cell membrane increases in size until it buds off of the cell to live independently; yeast increase in number |
| sporulation | spores are released by the parent cell; then each spore germinates and grows on its own |
| binary fission | a cell splits almost perfectly in half then two new cells are produced(no parent b/c parent forms two daughter cells) |
| cell division | process by which cells divide to make 2 identical daughter cells |
| apical meristem | place of cell division in the plant |
| cells divide for.... | growth and repair |
| chromosomes | threadlike structures in the nucleus containing genetic info. |
| chromatin | consists of DNA tightly coiled around proteins in the nucleus |
| chromatid | replicated chromosomes(after they are doubled) |
| centromere | area where the chromatids are attached |
| centriole | structures located in the cytoplasm involved in mitosis |
