Kingdom Plantae
Plant Evolution and Bryophytes

2. K.Plantae Characteristics
EUKARYOTIC
MULTICELLULAR
AUTOTROPHIC – use photosynthesis
SESSILE (Stationary)
CELL WALLS OF CELLULOSE

3. Ecological Role of Plants
The base of most food webs - collect the sun’s energy
Produce Oxygen
Provide shelter

4. What do plants need to survive?
Sunlight
Minerals
Carbon dioxide
Oxygen
Water

5. How did the evolution of plants occur?
Directions: Using the marker board at your table, create a timeline placing the following list of events in order from oldest to most recent.
Be able to defend your timeline.
Marker boards, butcher paper, scratch paper…etc

6. List of events
Water conducting (vascular) tissue Gymnosperms (cone bearing plants with seeds) Green Algae (plant like protist) Ferns (with vascular tissue) Naked seeds (not in fruit) Angiosperms (flowering plants) Mosses (lack vascular tissue) Flowers, seeds in fruit

7. Ferns and their relatives
Flowering plants
Cone-bearing plants
Ferns and their relatives
Mosses and their relatives
Green algae ancestor
Flowers; Seeds Enclosed in Fruit
Seeds
Water-Conducting (Vascular) Tissue
Copy correct timeline into journal

8. Green Algae Non vascular Plants
Ancestor of all land plants
Mosses
Explain the evolutionary hurdle of going from water to land

9. Nonvascular Plants
Do not have vascular tissue (No stems or leaves) and cannot grow tall.
Require a constantly moist environment
Water is required for reproduction
Nutrients move by diffusion
Reproduce by spores
Known as Bryophytes

10. Bryophytes (1st land plants)
Ex. Mosses
Anchor to land by rhizoids
Thin cells that absorb water and minerals and anchor them to the land
Rhizoids
