2. Reflection
Prompt: What are two differences between nonvascular and vascular plants? (write in complete sentences)

3. Why does the lemon looks yellow and leaves look green?
Because lemon reflects yellow light

Mosses, Liverworts, Hornworts
Low growing
Can pass materials only from one cell to the next
Cell walls provide support
They get water directly from their surroundings.

7. Gametophyte & Sporophyte

8. Moss Reproduction Video

9. What is a seed plant? All have vascular tissues
Most plants are seed plants (10 to 1)
Seed plants use seeds to reproduce
All seed plants have roots, leaves and stems
In plants what you see are the sporophyte stage.

12. How can seeds be scattered?
Animals
Water
Wind
Shooting out of plant.

13. What is Germination?
Early Growth Stage of Embryo

14. What role do leaves play in plant?
Leaves capture the sun’s energy and carry out the food making process of photosynthesis

15. Structure of leaf

16. What are the functions of stems?
Carry substances between the leaves and roots
Support the plant and hold up the leaves
Store food.

17. What are the functions of roots?
