Answer:

Angiosperms have seeds with an 3n endosperm due to double fertilization.

Explanation:

  • Double fertilization is found only in flowering plants.
  • In angiosperms, the female gametophyte does not grow after reaching eight nucleate stage.
  • After fertilization and triple fusion, the zygote and primary endosperm are created and further growth of embryo sac continues.
  • Triple fusion is the fusion of two haploid polar nuclei of female gametophyte and one male nuclei. This results in a  3n nucleus.
  • The developing embryo obtains nutrition from the endosperm.
  • If fertilization fails no endosperm is formed.

Make a decision about the molecule NaHCO3 classification organic or inorganic
motikmotik

<u>Answer:</u>

NaHCO_{3} is an inorganic compound.

<u>Solution:</u>

  1. Firstly, all the known definitions of organic compounds excludes Carbonic acid and it's salt from organic compounds except if 'C' is present in the cation.  
  2. Secondly, Sodium is a metal which organic compounds cannot posses as a compound.  
  3. Lastly, there is absence of C-H bond which is present in all the organic compounds.

Hence, we can conclude that NaHCO_{3}is an inorganic compound though there is presence of Carbon atom in it.
