How Are Plants and Fungi
Classified?
Objectives
• Observe the function of a plant stem.
• Describe the structures of vascular and
nonvascular plants.
• Describe the function of fungi.
Types of Plants
• There are over 270,000 types of plants in
the world
• In the plant kingdom, there are two large
groups
– Vascular Plants
– Nonvascular Plants
Vascular Plants
Vascular plants
– Means “having tubes”
– These tubes carry water and food to all the
different parts of the plant.
– Made up of three systems or parts…
• Roots
• Stem
• Leaves
Vascular Plants: Roots
Roots
– Help anchor the plant in the ground
– Absorb the water and nutrients from the soil
Vascular Plants: Stems
• Stems
– Connect the roots and the leaves
– Carry water and food
– Water in the stem help keeps the plant stand
up straight
Vascular Plants: Leaves
• Leaves
– Similar to a factory
– Make food and give off oxygen
– Chloroplasts in the
cells help vascular
plants make food.
Vascular Plants Question?
• What are the three systems that make up
vascular plants?
• Answer:
– Roots
– Stems
– Leaves
• What does each system do?
Nonvascular Plants
• The prefix “non”
– Means not
• Therefore…Nonvascular means:
– They do NOT have tubes
• They absorb water directly
– Cell by cell…like a sponge!
Nonvascular Plants
• Grow in:
– Damp and shady places
– Close to the ground
• Do not have real roots
– Instead have root like parts that anchor them
• Leaflike parts make food
Nonvascular Plants
• Three groups
– Mosses
• Grow where it is moist
• Grow on buildings, or brick walls, and damp
pavement
– Liverworts
• Grow in damp forests and along rivers
– Hornworts
• Same as liverworts
Nonvascular Plants Question?
• How do nonvascular plants get water and
nutrients?
• Answer:
– They absorb water and nutrients directly from
their environments and move them from cell
to cell
• Name three examples of nonvascular
plants.
Fungi
• Organisms that
absorb food and
can’t move about.
• They can not make their own food, so their cells do
not have chloroplasts.
• Absorb nutrients from living things and from the
remains of living things.
• Fungi includes molds, mushrooms, and sac fungi.
