Many wind-dispersed seeds, such as those of the dandelion, store their primary energy reserves as lipids (triglycerides) rather than carbohydrates like starch.
Which statement correctly explains the biochemical advantage of storing lipids instead of starch in these wind-dispersed seeds?
Lipids are highly polar molecules, which prevents them from affecting the water potential of the seed cells during dormancy.
Lipids have a higher ratio of carbon-hydrogen bonds to carbon atoms, which allows more energy to be stored per unit mass.
Lipids contain a higher proportion of oxygen than starch, reducing the amount of external oxygen required for aerobic respiration during germination.
Lipids are highly soluble in water, allowing them to be rapidly mobilised and transported directly to the growing plant embryo.
