Plants
| Term | Definition |
|---|---|
| petals | each of the segments of the corolla of a flower, which are modified leaves and are typically colored |
| photosynthesis | the process by which green plants use sunlight to synthesize foods from carbon dioxide and water |
| dormancy | when a plant is alive but not actively growing |
| phloem | the vascular tissue in plants that conducts sugars and other metabolic products downward from the leaves |
| xylem | the vascular tissue in plants that conducts water and dissolved nutrients upward from the root and also helps to form the woody element in the stem |
| sepals | the leaves that enclose the flower bud |
| cellular respiration | the production of energy from the intake of oxygen and the release of carbon dioxide |
| tropism | the turning of all or part of an organism in a particular direction in response to an external stimulus |
| transpiration | process by which moisture is carried through plants from roots to small pores on the underside of leaves, where it changes to vapor and is released to the atmosphere |
| stamens | the male fertilizing organ of a flower, typically consisting of a pollen-containing anther and a filament. |
| cuticle | a protective and waxy or hard layer covering the epidermis of a plant |
| gravitropism | the movement or growth of a plant in response to gravity |
| anther | the part of a stamen that contains the pollen |
| stomata | any of the pores in the epidermis of the leaf or stem of a plant, forming a slit of variable width that allows movement of gases in and out |
| hydrotrophism | growth or movement response of a cell or an organism to moisture or water |
| pistil | the female organs of a flower, comprising the stigma, style, and ovary |
| glucose | made in photosynthesis is transported around the plant as soluble sugars which are used in respiration to release energy for use by the plant's cells |
| fertilization | Coming together of egg cell and sperm cell; once pollination happens, ovule closes; then sperm cell fertilizes an egg cell in ovule; fertilized egg then develops into embryo |
| pollination | the transfer of pollen to a stigma, ovule, flower, or plant to allow fertilization |
| ovary | part of the pistil which holds the ovule(s) and is located above or below or at the point of connection with the base of the petals and sepals |
| ovules | the part of the ovary of seed plants that contains the female germ cell and after fertilization becomes the seed |
| filament | a stalk-like structure that attaches to the base of the flower and supports the anther, which is the structure that produces pollen |
| stigma | The part of the pistil where pollen germinates |
| style | a long, slender stalk that connects the stigma and the ovary |
| germinate | sprouting of a seedling from a seed |
| perfect flowers | has both the male and the female reproductive parts |
| imperfect flowers | has only one sexual reproductive organ |
| phototropism | plants that grow towards the sun |
| chlorophyll | causes plants to be green |
