Plant Classification, Parts of Flower & Seeds
| Term | Definition |
|---|---|
| vascular plants | plants with a system of roots, stems and leaves; plants with xylem and phloem |
| Non Vascular Plants | plants with NO system of roots, stems and leaves, no xylem or phloem (examples: moss and liverworts) |
| Xylem | system of "tubes" in the plant that carries water from roots to other parts of the plant |
| Phloem | system of "tubes" in the plant that carries the plant's food from leaves out to rest of the plant |
| Gymnosperms | vascular plants that produce seeds (example; cycads, conifers, ginkgoes) |
| Angiosperms | vascular plants that produce flowers and seeds |
| Monocot | an angiosperm (flowering plant) with only one cotyledon; plant has narrow leaves with parallel veins and fibrous root (ex: corn, lily) |
| Dicot | an angiosperm (flowering plant) with two cotyledons; plant has broad leaves and tap root system (ex: bean, maple) |
| Cotyledon | the first leaves of the young plant, the seed leaves |
| Fibrous root | root system that spreads and has more than one significant root |
| Tap root | root system that has one major root (examples: carrot, turnip and potato) |
| Pistil | the female part of the flower |
| Stigma | top opening of the pistil |
| Style | neck portion of the pistil |
| Ovary | at base of the pistil, where seed is formed |
| Stamen | male part of the flower |
| Filament | stem-like portion of the stamen |
| Anther | the top portion of the stamen, where pollen is produced |
| Pollination | when pollen is spread by wind, bees, insects, birds |
| Fertilization | the process by which a seed is formed within the flower |
| Germination | the process by which a seed becomes a plant |
| Seed coat | Hard protective cover for embryo |
| Embryo | baby plant |
| Food supply | food stored in seed to support the embryo as it grows into a young plant |
