Hints
Seed formation is a more dependable reproductive strategy in angiosperms because:
| 1. | Pollination and fertilization are independent of water |
| 2. | Seeds have better adaptive strategies for dispersal |
| 3. | Seeds have sufficient food reserves |
| 4. | New genetic combinations are generated during seed formation |
Subtopic: Seed |
Level 3: 35%-60%
Hints
Wind-pollinated flowers are characterized by the following, except:
| 1. | Light and non-sticky pollen grains |
| 2. | Well-exposed stamens |
| 3. | Many ovules in each ovary |
| 4. | Large, often-feathery stigma |
