Identify the function of specific
plant and animal parts.
Vascular Plants
• Vascular Plants contain two
networks of tubes in their stems,
leaves, and roots.
• One of these networks transports
water, and the other transports food
made in the leaves to the other
plant parts.
Types of Vascular
Plants
ferns
seed-bearing plants
flowering plants
Parts of a Vascular Plant

Roots
Stem
Leaves
Ovule
Stigma
Ovary
Petal
Anther
Roots
• Water and nutrients from the soil enter
the plant through the roots.
• Water tubes in the roots carry water to
water tubes in the stems.
Stems
• Water tubes in the stem then carry
water to water tubes in the leaves.
• Some of the water then evaporates
into the air through a process called
transpiration.
Leaves
• Food tubes carry food made in the
leaves to food tubes in the stem
and roots.
• Some food tubes run all the way
from the leaves down to the roots.
Ovule
• This part contains the egg cell.
Stigma
• tip of pistil which catches the
pollen grains
Ovary
• where ovules are made
Petal
• colorful leaf that helps
attract insects
Anther
• This part of the stamen contains
pollen.
What is pollen?
• The fine powder like material
consisting of pollen grains that is
produced by the anthers of seed
plants.
After you strip away
the blossom of the
male flower, the pollen
is readily visible.

What does a plant
need to survive?
• Soil
• Light
• Water

Plants may have adaptations in order to
obtain these basic needs, much like the
Venus Fly Trap.
Stages in Reproduction
• An insect or the wind carries pollen grains
from another flower to this one.
• The pollen grains land on the stigma and a
pollen tube grows down through the style to
the ovary.
• The nucleus of the pollen grain passes down
the tube. It fertilizes the egg cell inside the
ovule.
• The fertilized egg cell develops into an
embryo. The ovary becomes the fruit and the
ovule becomes the seed.
