  Normal Size     Small Size show me how


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
