Chapter 7 Vocabulary: Parts of a flower
Filament
A slender stalk that supports the anther, where the pollen develops
Pistil
Female reproductive organ inside the flower of an angiosperm; consists of a sick stigma, where pollen grains land, and an ovary, leads to eggs
Pollination v.s fertilization
Pollination: transfer of pollen form an anther to a stigma, Fertilization when the pollen (male) reaches the eggs.
Pollination v.s germination
Pollination: transfer of pollen from an anther to a stigma, Germination: the process of growth from a seed to a plant
Germination
Series of events that results in the growth of a plant from a seed
Ovary
Swollen base of an angiosperms pistil where egg- producing ovules are found, contains a seed, deavelops in a baby plant
Style
A long slender stalk that connects the stigma and the ovary, location where pollen tubes travel to deliver sperm cells to the egg
Sepal
Covers the bud and protects it from cold, protective layer, lower outer part (petal) covers bud before flower, sprouts from it
Stigma
Female part of a flower, part of the pistil where pollen germinates, traps pollen, covered in sticky waxy substance, landing zone for bees
Ovule
In seed plants, the female reproductive part that produces eggs
Stamen
Male reproductive organ inside the flower of an angiosperm; consist of an anther, where pollen grains form, and a filament, produces pollen grains
Anther
Oval shaped structure, male, produces pollen
Petals
To attract pollinators, usually the colorful part of a flower, considered a leaf
Pollination
Transfer of pollen grains to the female part of a seed plant by agents such as gravity, water, wind, and animals, transfer of mature pollen grains from the anther to the stigma
Pollinators
Wind, insects, birds and other animals
