ANTHER
The male part of a flower which produces the pollen.
CARBON DIOXIDE
A gass green plants use to make food. Plants get this from the air.
CARPELS
The female organs of a flower. They have three parts: 1) an ovary,
holding one or more egg cells. 2) style and 3) stigma which is at the
tip of the style and receives the pollen.
CELLS
One of the building blocks of which living things are made. Plants
consist of many cells. Some may be specialized for particular jobs.
CHLOROPHYLL
Chlorophyll is the green matter that is needed to make food for the
plants
CHLOROPLASTS
Chloroplasts are in the leaf cells and are full of chlorophyll (green
matter).
COTYLEDON
The hard outer case of the seed which holds the embryo (baby part of
the plant) and gives it a food supply.
CORTEX
In the root, it is the layer of cells between the center and the
edge.
DICOT (DICOTYLEDON)
A flowering plant that has 2 cotyledons in the embryo. The bean seed
is a dicot. It has two special structures called cotyledons which are
part of the embryo.
DISSEMINATION
The act or process of scattering or the state of being scattered
widely. The process of seeds traveling from one place to another.
DORMANT
When a seed falls to the ground and may lie there "asleep"
EMBRYO
The developing life of a new plant or animal, due to the combining of
a male and female reproductive cells. The "baby" plant. The part of a
seed that develops into a new plant.
ENDANGERED
Anything whose existence is threatened.
ENDOSPERM
Monocot plants store food in a part of the seed called the endosperm.
EPIDERMIS
The out layer of cells on a plant. It protects the inside parts. It
is like our skin.
FATS
An oily liquid or greasy substance making up the main bulk of the
tissue of animals, and widely distributed in the seeds of a plant.
FERTILIZE
To put manure or certain chemicals put in the soil as food for the
plants.
GERMINATION
A seed begins to grow. The growth of a seed of a first tiny shoot and
root.
GAMETE
The egg or the sperm in the flower.
HITCHHIKE
A seed travels by attaching itself to an animal or person.
MISTLETOE
An evergreen plant with waxy white berries growing on certain trees.
Sprigs of mistletoe are used as Christmas decorations
MONOCOTS
A plant that has only one cotyledon. The corn seed has only one
cotyledon.
MONOCOTYLEDON
A seed with only one cotyledon
OVARY
The female part of the flower, which produces the eggs that are
needed for making seeds
OXYGEN
A gas that has no color or smell. Oxygen makes up one-fifth of the
air. Living things need oxygen to live, and fires need it to burn.
Oxygen is a chemical element. Green plants make this gas when they
make food.
PETAL
One of the parts of a flower that is arranged in a circle. They are
the colored part of the flower.
PHOTOSYNTHESIS
The process by which green plants use carbon dioxide, water and
sunlight to make their own food. Made up of two words: photo, which
means light, and synthesis, which means putting together. A plant
puts water and carbon dioxide together. It uses light as its helper.
It also uses chlorophyll as a helper. When these things are put
together they make sugar and oxygen.
PISTAL
The female seed-producing part of a flower.
POLLEN
The fine powder produced by the anther inside a flower that contains
the male sperm cells.
POLLEN TUBE
A tube that grows from a pollen grain on the stigma of a flower down
through the style into the ovary.
PREDATORS
An animal that lives by eating other animals.
PROTEIN
A substance that is found in all living cells of animals and plants.
It is necessary for growth and life.
ROOT HAIRS
They are like hair. They come out of the root like a branch. They
absorb the water and food for the plant.
SEED COAT
The outer covering of a seed.
SEPAL
The outer green parts of the base of the the flower. They protect the
flower bud before it opens. Inside the sepals are the colored petals.
STAMEN
The male organ inside the petals. The part of a flower that produces
pollen.
STARCH
A white food substance (sugar) that is made and stored in most
plants.
STELE
The center of the root. It holds the veins that carry water and
sugar.
STIGMA
The tip of the female part of the flower, which receives the male
pollen grains
STOMATA
Tiny pores on the underside of the leaves (stomota-plural for stoma).
Carbon dioxide and oxygen enter and leave the plant through these
tiny pores.
VASCULAR RAYS
Cells in the root that carry water sideways.
VEINS
Tubes which take water to each and every cell of the plant. The veins
help to strengthen and support the plant.
XYLEM
Veins that carry water and food to the plant.
