How Are Plants and Fungi Classified?

2. Objectives Observe the function of a plant stem.
Describe the structures of vascular and nonvascular plants.
Describe the function of fungi.

3. 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

4. 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

5. Vascular Plants: Roots
Help anchor the plant in the ground
Absorb the water and nutrients from the soil

6. Vascular Plants: Stems
Connect the roots and the leaves
Carry water and food
Water in the stem help keeps the plant stand up straight

7. Vascular Plants: Leaves
Similar to a factory
Make food and give off oxygen
Chloroplasts in the cells help vascular
plants make food.

8. Vascular Plants Question?
What are the three systems that make up vascular plants?
Answer:
Roots
Stems
Leaves
What does each system do?

9. Nonvascular Plants The prefix “non” Therefore…Nonvascular means:
Means not
Therefore…Nonvascular means:
They do NOT have tubes
They absorb water directly
Cell by cell…like a sponge!

10. Nonvascular Plants Grow in: Do not have real roots
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

11. Nonvascular Plants Three groups Mosses Liverworts Hornworts
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

12. 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.

13. 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.
