Flower Parts/Reprodu

Flower parts and reproduction for NC 6th grade

TermDefinition
petals brightly colored, to attract insects such as bees, for pollination
sepals external, protective covering of the flower bud
stamen male part of the flower, made up of the anther and filament
anther in seed plants, the part that produces pollen which is carried from flower to flower, and is part of the stamen
pistil female parts of the flower consisting of the stigma, syle, and ovary
ovary in seed plants, the female reproductive part that produces the egg
fertilization the union of male pollen and female ovules to create seeds
reproduction the production of new individuals or offspring in plants
pollination the act of transferring pollen grains from the male anther of a flower to the female stigma
epidermis a single layer of cells that covers the leaves, flowers, roots and stems of plants. It forms a boundary between the plant and the external environment.
stomata the tiny openings in the epidermis of a plant, through which gases and water vapor pass. Permits the absorption of carbon dioxide necessary for photosynthesis from the air, as well as the removal of excess oxygen.
guard cell each of a pair of curved cells that surround stomata. They open and close the stomata.
glucose a sugar produced in plants during photosynthesis
photosynthesis the process by which green plants use sunlight to make glucose from carbon dioxide and water. Photosynthesis in plants involves the green pigment chlorophyll and produces oxygen
respiration The opposite of photosynthesis. During respiration, plants absorb oxygen and use them to create water, carbon dioxide, and energy, which helps the plant grow.
transpiration Transpiration is the process where plants absorb water through the roots and then give off water vapor through pores in their leaves.
cholorophyll a green pigment, present in all green plants, responsible for the absorption of light to provide energy for photosynthesis.
tropism the response of an organism, esp a plant, to an external stimulus by growth in a direction determined by the stimulus like water or sunlight
stimulus something that provokes a response in a plant, such as sunlight or water
filament supports the anther to make it accessible to insects
stigma sticky portion at the top of the style wherenthe pollen grains usually land
style part of the pistil, between the ovary and stigma, that transports pollen to the ovary
ovule the female egg in the plant
