• Bag on the floor

Lesson goals

• You can classify plants into eight phyla.
• You can name the features of vascular plants and green algae and you can give examples of them.
• You can name the features of spore-bearing plants and seed plants and you can give examples of them.

Classification of plants

Distinguishing features:

- Types of chloroplasts

- The structure of the plant

- The way the cell organelles work

Vascular plants

- Plants that use vessels for transporting 

substances.

- Plants that have stems, roots and leaves.

- Produce either seeds or spores

          - Spores are cells that can grow 

             into new plants.

Seed plants 

- have roots, stems, leaves and flowers 

- are all part of the phylum vascular plants

Spore-bearing plants 

- can have roots, stems and leaves but do not have flowers 

- Some spore-bearing plants are vascular plants, others are algae or mosses.

Seed plants

Algae

- Most algae grow in water. 

- They do not need roots and stems. 

- They also have no leaves and no flowers. 

- Some algae can reproduce using spores. 

- Many unicellular (single-celled) algae reproduce by cell division.

Green algae

Algae with chloroplasts.

- Unicellular - example: Pleurococcus

- Multicellular - example: Sea lettuce 

This plant,
an oak,

This plant,
a bracken fern,
belongs to

1. Algae
2. Spore-bearing plants
3. Seed plants

This plant,
a dandelion,
belongs to

1. Algae
2. Spore-bearing plants
3. Seed plants

Algae are classified in the kingdom of?

1. Plants
2. Fungi
3. Protists

How to study classification

- read all the texts, especially look at the learning goals

- make, check and evaluate all the tasks

- learn all the special words (use flash cards, quiz eachother)

- make mind maps, not just summaries, see the connections! 

- do not underestimate, but do not give up either!
