Double Fertilization Reduces the Energetic Cost of Reproduction

question 33

Multiple Choice

Double fertilization reduces the energetic cost of reproduction.In gymnosperms,the female gametophyte stockpiles food for the embryo in advance of fertilization.The investment is wasted if no zygote ever forms.In contrast,double fertilization ensures that an angiosperm devotes energy to the zygote only if sperm fertilizes egg.Where is this energy stored in a fertilized angiosperm?

• B)Stigma
• C)Zygote
• D)Pollen
