nucleus,chloroplast,cell
membrane,cell wall,and
cytoplasm.
Parts of a Plant
•
•
The three parts
of a plant are:
the roots

the stem
•
the leaves
The Needs of a Plant
•
In order for plants to survive,
they need sunlight,water,
minerals, and air.
Roots
•
The roots are the part of a
plant that grows underground.
•
The roots help hold the plant
in the ground.
•
The roots also take in water
and minerals from soil.
Stem
•
The stem helps the plant
stand upright.
•
The stem supports the plants.
•
It carries food from leaves to
other plant parts.
•
The roots carry water and
minerals from roots.
•
The stem is the part of a plant
that supports the plant.
Leaves
•
The leaves are the main food
making part of the plant.
•
It uses the sun's energy,carbon
dioxide, and water to make food.
•
The leaves takes in sunlight.
•
The leaves have chlorophyll
which it traps energy from the
sunlight.
•
It also uses a gas from the air
called " carbon dioxide."
Life Cycle of a Plant
•
The life cycle is the stages of
the plant life.
•
First it is a seed.Then it is a
sprout.Next the plant is a
vine.And then it is a young
pumpkin.Finally it is a
pumpkin.
Conifers
•
Pine cones come from
conifers.
•
First the ripe seeds is from a
large cone germinate in the
soil.Then a new pine tree
grows.Next it makes two kinds
of cones.After that pollen from
the small cone falls on the
larger cone.Finally the larger
cone grows with seed so
inside.Ripe seeds fall to the
ground.
Life Cycle of a Flowering
Plant
•
A flowering plant has a male
part and a female part.
•
First a seed might become a
new plant.Then a new plant
grows.Next the plant is an
adult.After that the plant
flowers.Insects,such as
bees,carry pollen to the
eggs.Finally flowers become
fruits with seeds.
