- RootsTermAnchor the plant and take in water and minerals
- StemTermHolds the plant up and carries water and food
- LeafTermThe main place where a plant makes food
- FlowerTermThe part of a plant that makes seeds
- FruitTermA ripened ovary that holds seeds
- SeedTermHolds a baby plant and food to start growing
- PetalTermColorful part of a flower that attracts pollinators
- SepalTermGreen leaf-like part that protects a flower bud
- StamenTermMale part of a flower that makes pollen
- AntherTermTop of the stamen that holds pollen
- FilamentTermThe stalk that holds up the anther
- PistilTermFemale part of a flower
- StigmaTermSticky top of the pistil that catches pollen
- StyleTermTube that connects the stigma to the ovary
- OvaryTermPart of the pistil that holds the ovules
- OvuleTermPart of the ovary that becomes a seed
- PollenTermTiny grains that carry male cells of plants
- PollinationTermMoving pollen to the female part of a flower
- PollinatorTermAn animal such as a bee that moves pollen
- FertilizationTermWhen male and female cells join to start a seed
- GerminationTermWhen a seed begins to grow
- PhotosynthesisTermPlants turn light, water and carbon dioxide into sugar and oxygen
- ChlorophyllTermGreen pigment that captures light
- StomataTermTiny leaf openings that let gases in and out
- Guard cellsTermCells that open and close the stomata
- TranspirationTermWater evaporating from leaves
- XylemTermTubes that carry water up from the roots
- PhloemTermTubes that carry sugar through the plant
- TaprootTermOne thick main root, like a carrot
- Fibrous rootsTermMany thin roots, like grass
- Root hairsTermTiny extensions that absorb water
- CotyledonTermA seed leaf that stores food in the seed
- MonocotTermA flowering plant with one seed leaf, like corn and grass
- DicotTermA flowering plant with two seed leaves, like beans
- AngiospermTermA plant that makes flowers and fruits
- GymnospermTermA plant with seeds not in fruit, like pine trees
- ConiferTermA tree that makes cones, such as pine or spruce
- DeciduousTermA tree that loses its leaves each fall
- EvergreenTermA plant that keeps green leaves all year
- AnnualTermA plant that lives one growing season
- BiennialTermA plant that lives two years
- PerennialTermA plant that lives for many years
- Vascular plantTermA plant with tubes for carrying water and food
- Nonvascular plantTermA plant without such tubes, like moss
- SporeTermA tiny cell that can grow into a new fungus or fern or moss
- FernTermA plant with fronds that reproduces with spores
- MossTermA small nonvascular plant that grows in damp places
- TropismTermA plant's growth response to something like light or gravity
- PhototropismTermGrowing toward light
- GravitropismTermRoots growing down and shoots growing up in response to gravity
- DormancyTermA resting period when growth slows
- Seed dispersalTermHow seeds travel away from the parent plant
- BulbTermAn underground storage stem, like an onion or tulip
- TuberTermA thick underground stem, like a potato
- RhizomeTermAn underground stem that spreads sideways
- CambiumTermA thin growing layer that makes new wood and bark
- Tree ringsTermRings in a trunk showing one year of growth each
- HeartwoodTermThe old, dense center of a tree trunk
- BarkTermThe protective outer covering of a tree
- Carnivorous plantTermA plant that traps and digests insects, like a Venus flytrap
- Parasitic plantTermA plant that takes food from another plant
- EpiphyteTermA plant that grows on another plant without harming it
- CompostTermDecayed plant matter that enriches soil
- Nitrogen, phosphorus and potassiumTermThe main nutrients in fertilizer
- What do plants release during photosynthesis?TermOxygen
