Flashcards

Seed: A structure containing a plant embryo, stored food, and a protective coat.
Germination: The process by which a seed begins to sprout and grow into a seedling.
Cotyledon: Seed leaf that stores food for the seedling before it can photosynthesize.
Root: The part of a plant that anchors it in soil and absorbs water and minerals.
Stem: The part of a plant that supports the leaves and carries water and nutrients.
Leaf: The plant's main organ for photosynthesis, capturing sunlight and absorbing CO2.
Flower: The reproductive organ of flowering plants, containing stamens and pistils.
Stamen: The male part of a flower; produces pollen.
Pistil: The female part of a flower; contains the egg cells and develops into fruit after fertilization.
Pollination: Transfer of pollen from stamen to pistil, carried by insects, wind, or other agents.
Fertilization: Fusion of a pollen cell and an egg cell to form a new plant embryo inside a seed.
Fruit: The ripened ovary of a plant that surrounds and protects seeds.
Seed dispersal: The spreading of seeds away from the parent plant by wind, water, animals, or explosive mechanisms.
Photosynthesis: Process where plants use sunlight, water, and CO2 to make sugar (glucose) and release oxygen.
Annual plant: A plant that completes its entire life cycle in one year, like sunflowers or corn.
Perennial plant: A plant that lives for more than two years and regrows each season, like oak trees.
