Answer: Nourishment for the developing embryo.
- A A hard protective coat around the seed
- B Nourishment for the developing embryo
- C Auxins and gibberellins that trigger germination
- D Storage of water absorbed during imbibition
Correct answer: B. Nourishment for the developing embryo
Explanation: Endosperm is nutritive tissue in angiosperm seeds. It stores starch, oils, and proteins to nourish the developing embryo during germination.
Double fertilisation in angiosperms: one male gamete fuses with the egg to form the diploid zygote (syngamy), while the second fuses with the two polar nuclei to form the triploid primary endosperm nucleus (triple fusion). Image: Triploid, CC BY 3.0, via Wikimedia Commons.
