|---|---|
| Which direction are sugars transported by the vascular system? | Up and Down |
| List four types of seed dispersal. | Water, Wind, Insect, Animal Internal, Animal External |
| What are the functions of the roots? | absorb H2O and dissolves nutrients from moist soil |
| 5.What happens to the seed when there is enough water, but not light? | OMIT |
| 6.What are two things the stem does? | Transport water and sugars, holds stems and leaves |
| 7. The first true plants were probably most similar to modern | algae (BUT/OR our first plants closely related to mosses). |
| 8. Seed plants do not rely on standing water to reproduce. They rely on what process? | pollination |
| 9. Seed plants whose seeds are not enclosed in fruit are called | gymnosperms (gymnosperms, angiosperms, bryophytes) |
| 10. What type of seed dispersal would a fleshy fruit have? | Eaten and discarded by animals |
| 11. How many seed leaves do dicots have? | 2 |
| 12. Why did the first true plants need to live in watery environments? | For reproductive purposes (CARRY SPERM TO THE EGG) AND to have water for absorption since they are non-vascular and have no roots for water absorption. |

| 21. Seedless plants disperse to new areas using what form of dispersal? | spores |
| 22. Colorful fragrant flowers are most likely pollinated by what? | animals |
| 23. Pine trees each have two different kinds of cones. These are called what? | Male pine cone and female pine cone |
| 24. In scientific terms, a fruit is a flower's | mature ovary |
