2 Describe ways in which you think sunflower seeds can be dispersed.
Answers
Answer:
1. Sunflower seeds disperse through the actions of people and animals as well as wind and water.
2. Most native sunflowers species, including wild common sunflower, have nutritious seeds less than 1/4 inch long.
3. Birds peck seeds out of the flower heads, knocking some seeds to the ground.
4. Sunflower seeds are transported as bulk cargo or as break-bulk cargo in bags of woven natural materials (e.g. jute) or woven plastic bags.

Explanation:
The sunflower family, known to botanists as Asteraceae, is the largest family of flowering plants on Earth, including species like daisies, asters and thistles. In some regions, sunflowers account for up to 20 percent of the plant life. Sunflowers share in common a radial flower structure, the petals arranged around the center of the flower like rays around a sun. All flowering plants bear seeds, and seed dispersal is one of the adaptations that account for a plant's reproductive success.When plants first developed seeds, they gained the benefit of extra protection and better nutrition for developing seedlings. Seeds served another purpose, however, in helping plants to distribute their young to more distant locations. Looking at the range of seed shapes in the sunflower family provides a primer of the diversity and effectiveness of seed dispersal methods.
