Describe the life cycle of a sunflower from seed to seed again, mentioning at least the stages: seed, germination, vegetative growth, flowering and seed set.
Answer
Seed – Germination – Vegetative Growth – Flowering – Seed Set – Dormancy – Re‑seeding
The correct answer is Seed – Germination – Vegetative Growth – Flowering – Seed Set – Dormancy – Re‑seeding — Step 7: The cycle repeats when these new seeds germinate again.
Step-by-step solution
- Step 1: Start with a sunflower seed planted in soil.
- Step 2: The seed absorbs water and begins germination, sprouting a shoot.
- Step 3: In the vegetative stage the plant grows leaves, stems and roots, gaining height and strength.
- Step 4: When conditions are right, the plant sends up a tall flower head – the flowering stage.
- Step 5: After pollination, the flower develops seeds – the seed set stage, which eventually mature into new seeds.
- Step 6: Mature seeds drop or are dispersed, often entering a period of dormancy until the next season.
- Step 7: The cycle repeats when these new seeds germinate again.
Common mistake: Omitting the seed set stage
Concept tested: Life cycle of plants
