Why do plants store energy as carbohydrates and not as fats?

Plants though, reserve energy through starch (carbohydrate) and not through fats as it would be expected. This doesn''t mean they don''t use fats at all (i.e. oil seeds). An energy storing molecule must save energy (as the name indicates), but it shouldn''t be too heavy and it should be stable enough so that it''s functional within the organism.
