What is the starchy material inside seeds that provides nutrients for the embryonic plant called?
PilotLPTM [1.2K]

Answer:

Endosperm

Explanation:

  • An endosperm develops in a seed after a process known as double fertilisation occurs in the ovary of a flower whereby one of the sperm nuclei inside a pollen grain reaches the interior of the embryo sac and fuses with the two polar nuclei forming a triploid nucleus which is the primary endosperm.
  • The endosperm supports embryonic growth by supplying nutrients and acting as a mechanical barrier to protect the embryo during seed development and germination.
  • The endosperm has living cells that regulate seed germination.
  • The endosperm is secreted with hydrolysis enzymes through the gibberellin hormone that induces the synthesis of amylase in the aleurone layer.
  • The hydrolysis enzyme catabolizes starch which act as energy source providing carbon and nitrogen for seed germination and seedling development.
