12. Gut develops from “mouth” end - J. Protostoma

13. Halteres - G. Flies

14. Head, thorax, and abdomen with six walking legs - H. Insecta

15. Inventor of photosynthesis - C. Cyanobacteria

16. Lactic-acid fermentation - F. Firmicutes

17. Lignin and vascular tissue - L. Vascular plants

18. Nucleus - E. Eukarya

19. Pollen - K. Seed plants

20. Two tests made of silica (glass) - D. Diatoms

21. Notochord - B. Chordata

22. Vertebral column - M. Vertebrata

Angiosperms are the type of plants which bears flowers and flowers contains carpel and stamen.
Embryophytes are also called as land plant. The name embryophyte was given because they nurture the young embryo sporophyte during the early stages of its multicellular development within the tissues of the parent gametophyte. Therefore the embryo is retained within parent.
Gut develops from mouth end in protostomes during embryonic stages.
Halteres are small knobbed structures modified from the hind wings in flies. They vibrate during flight and help the insect fly better.
Insecta consists of the animals with well distinct Head, thorax, and abdomen with six walking legs.
cyanobacteria were present on earth approximately as early as 2.7 billion years ago, they carry out photosynthesis and that is why they are known as inventor of photosynthesis.
Firmicutes carry out Lactic-acid fermentation to yield lactic acid as an end product.
Vascular plants have Lignin and vascular tissue which make the stem stiff.
Eukaryotic cells have membrane-bound organelles like the nucleus.
Seed plants produces pollens for sexual reproduction and formation of seeds.
Diatoms are the only organism on the planet with cell walls composed of transparent, opaline silica and ornamented by intricate and striking patterns of silica.
Notochord is only present in Chordata, in other animals it is found only during embryonic development.
Vertebrates comprise all species of animals within the subphylum Vertebrata and all of them have vertebral column.
