Term
LEAVES
Definition
A PLANT PART THAT GROWS OUT OF THE STEM; THIS IS WHERE THE PLANT MAKES IT'S OWN FOOD (PHOTOSYNTHESIS) LEAVES TAKE IN SUNLIGHT AND CARBON DIOXIDE THAT PLANTS NEED.
Term
GERMINATES
Definition
WHEN A NEW PLANT BREAKS OUT OF A SEED, AND STOPS LIVING ON STORED FOOD.
Term
ROOTS
Definition
THE PART OF A PLANT THAT HOLDS THE PLANT IN THE GROUND AND TAKES IN WATER AND MINERALS FROM THE SOIL. THERE ARE TWO TYPES: FIBROUS ROOTS & TAP ROOTS
Term
SEEDLING
Definition
A YOUNG PLANT.
Term
SEED
Definition
THE FIRST STAGE IN THE GROWTH OF MANY PLANTS. PLANTS REPRODUCE OR MAKE MORE PLANTS LIKE THEMSELVES BY FORMING SEEDS.SEEDS COME IN MANY DIFFERENT SHAPES AND SIZES. THEY FORM IN FLOWERS, IN FRUIT, OR IN CONES.
Term
CHLOROPHYLL
Definition
THE SUBSTANCE THAT GIVES PLANTS THEIR GREEN COLOR; IT HELPS A PLANT USE ENERGY FROM THE SUN TO MAKE FOOD.
Term
STEM
Definition
A PLANT PART THAT CARRIES WATER AND MINERALS FROM THE ROOTS UP TO THE LEAVES AND OTHER PARTS OF THE PLANT AND SUPPORTS THE PLANT ABOVE GROUND.
Term
PHOTOSYNTHESIS
Definition
THE FOOD-MAKING PROCESS OF PLANTS. THE PLANT TAKES IN ENERGY FROM THE SUN ALONG WITH CARBON DIOXIDE AND WATER. THE CHLOROPHYLL IN THE LEAVES USES ALL OF THESE THINGS TO MAKE A SUGAR THAT THE PLANT USES AS FOOD. THE PLANT LETS GO OF OXYGEN DURING THIS PROCESS.
Term
SIMPLE PLANTS
Definition
A PLANT THAT HAS NO ROOTS, STEMS OR LEAVES.
Term
CELLS
Definition
THE SMALL UNITS THAT MAKE UP ALL LIVING THINGS.
Term
CUTTING
Definition
A LEAF OR PIECE OF STEM THAT MAY BE USED TO GROW A NEW PLANT.
Term
What do plants need to live?
Definition
PLANTS NEED WATER, SUNLIGHT, MINERALS and CARBON DIOXIDE.
Term
SPORES
Definition
A TINY PLANT CELL THAT WILL DEVELOP INTO A NEW PLANT. FERN PLANTS HAVE SPORES.
Term
LIST FIVE WAYS SEEDS ARE SPREAD TO NEW PLACES.
Definition
FLUFFY SEEDS FLY IN THE WIND TO A NEW PLACE. SEEDS WITH HOOKS CATCH ONTO ANIMAL FUR AND GET CARRIED TO A NEW PLACE. ANIMALS EAT BERRIES WHICH CONTAIN SEEDS. THE SEEDS PASS THROUGH THEIR DIGESTIVE SYSTEM AND ARE "DEPOSITED" SOMEWHERE ELSE. WATER CARRIES SEEDS TO NEW PLACES. SOME PLANTS SHOOT THEIR SEEDS OUT. (CALLED BOLTING)
Term
LIST THE PARTS OF A SEED.
Definition
SEED COAT-PROTECTS THE YOUNG PLANT INSIDE OF THE SEED.
SEEDLING-A TINY PLANT THAT LIVES INSIDE OF EVERY SEED.
STORED FOOD-THE BIGGEST PART OF A SEED IS STORED FOOD THAT THE TINY SEEDLING USES AS FOOD UNTIL IT CAN GROW LARGE ENOUGH ROOTS TO GET FOOD ON ITS OWN.
Term
FIBROUS ROOTS
Definition
ROOTS THAT BRANCH OUT FROM THE STEM BUT DON'T GO DOWN DEEP. THE ROOTS ARE ALL AROUND THE SAME SIZE AND COVER A LARGE AREA. GRASS
Term
TAP ROOTS
Definition
THIS ROOT HAS ONE LARGE MAIN ROOT THAT GOES DEEP INTO THE SOIL. IT CAN HAVE SMALLER ROOTS COMING OFF OF IT. A CARROT OR RADISH IS A TAPROOT.
Term
STAMEN
Definition
PART OF A FLOWER THAT MAKES POLLEN
Term
DORMANT
Definition
WHEN A SEED DOES NOT GERMINATE FOR YEARS AND YEARS, WE SAY THAT IT IS DORMANT. (LIKE THE ONES THAT COME IN THOSE SMALL PACKAGES)
Term
FERTILIZATION
Definition
WHEN A PLANT'S SPERM CELL AND EGG CELL COMBINE.
Term
SEPAL
Definition
SMALL LEAF-LIKE PART OF A PLANT THAT PROTECTS THE FLOWER BUD
Term
SUGAR
Definition
THE FOOD THAT PLANTS MAKE DURING PHOTOSYNTHESIS
Term
OVARY
Definition
THE FEMALE PART OF THE FLOWER WHERE EGG CELLS ARE MADE
Term
STOMA
Definition
TINY OPENINGS ON THE UNDERSIDE OF LEAVES. WATER ESCAPES THROUGH THESE OPENINGS.
Term
POLLINATION
Definition
THE MOVEMENT OF POLLEN FROM THE STAMEN TO THE PISTIL. IT CAN BE MOVED BY ANIMALS (LIKE BEES) OR BY THE WIND.
