seed
a structure that contains a baby plant inside a protective covering
germination
the process where a seed grows into a plant
embryo
a baby plant (before it is born)
cotyledon
stored food for the baby plant
seed coat
the outer cover that protects the seed
disperse
to spread out or scatter
leaves
the part of the plant where photosynthesis takes place
stomata
small holes in the bottom of a leaf where carbon dioxide enters and oxygen exits
photosynthesis
the process where plants make sugar from water, carbon dioxide and sunlight
reactant
an ingredient
water, carbon dioxide and sunlight
reactants of photosynthesis
product
something that is made
glucose and oxygen
products of photosynthesis
stem
the part of the plant that has veins to transport food and water around the plant
xylem
a type of plant vein that carries water
phloem
a type of plant vein that carries sugar
up
the direction that water moves through the plant vein
down
the direction that sugar moves through the plant vein
hypocotyl
the lower stem (below the cotyledons)
epicotyl
the upper stem (above the cotyledons)
root
the part of the plant that absorbs water for the plant, holds the plant in the ground, and stores excess food for the plant
Food Chain
A chart that shows how energy is passed from organism to organism, starting with producers, then consumers, and finally decomposers.
radicle
the young root
flower
the part of the plant that produces seed and attracts pollinators for reproduction
