What life cycle adaptation do short day onions have? a=they form more onions than long day onions do. b=they start to form onions earlier in the year than long day onions do. c=they are better adapted to areas with days that are 14 to 16 hours long. d=they do not form onions until the summer months when the days are longer

a

explanation:

many plants naturally reproduce this way, but it can also be induced artificially. horticulturalists have developed asexual propagation techniques that use vegetative plant parts to replicate plants. success rates and difficulty of propagation vary greatly. monocotyledons typically lack a vascular cambium and therefore are harder to propagate.
