The white, fluffy part of the Salsify plant is very similar to the fluffy part of a Dandelion plant. What is its function?
-
Pollinating the seeds.
No. Pollination occurs with the flower, not with the fluffy part of the seed. -
Producing the seeds.
No. The fluffy part is part of the seed. It does not produce the seed. -
Dispersing the seeds.
Yes! The fluffy part of the seed catches the wind, letting a breeze scatter the seeds over a large area. -
Germinating the seeds.
No. Germination occurs after the seed reaches the proper conditions, with soil and water.
