Question

Why would it be advantageous to plants to be able to get acetyl-CoA from fatty acids?

		Plants lack the ability to synthesize carbohydrates
		Seeds have a limited amount of space and fatty acids are the most energy dense macromolecule
		Energy derived from photosynthesis primarily comes in the form of fatty acids
		Fatty acids are the macromolecule most easily taken up by the roots of the plant

It's apparently not B maybe?

Answer 1

Ans Seeds have a limited amount of space and fatty acids are the most energy dense macromolecule

Lipids are more reduced form of carbon then carbohydrate. Complete oxidation of 1 g of fat can produce 40 KJ or 9.3 KCal energy while oxidation of 1g of starch produces 15.8 KJ or 9.3 KCal.

So in some seeds lipids are stored. During germination, oil containing seeds metabolize stored triacylglycerols by converting lipids to sucrose . This is because the plants are not able to transport fats from endosperm to root and shoot . Hence they convert lipids to mobile form of carbon I e., sucrose.
