Biological Classification Test - 2

Cryptomycota lacks chitinous cell wall. In some strains, chitin is present in the inner layer of the resting spores.

This is false. In the absence of light, euglena can eat bacteria.

Chemoheterotrophs use organic chemicals and organic compounds as energy and carbon source respectively.

Lichen is mostly an association between blue green algae and fungus of class ascomycota.

Carl Woese divided kingdom monera into two groups i.e. archaea and bacteria domains. The Archaea domain contains prokaryotic organisms, which have a monolayer core of lipids in the cell membrane and distinct nucleotides in their 16S RNA, whereas Eubacteria domain contains diverse type of bacteria having peptidoglycan cell wall, glycogen as food reserve,naked DNA coiled to form nucleoid, absence of sap vacuoles and presence of 70S ribosomes.

Mycoplasma are devoid of cell wall around the cell membrane.

Fungal cell walls consist of chitin and glucans and they do not contain peptidoglycan and cellulose, thus fungal cell walls consist of everything except c and d.

Marine amoeba have silica shells on their surface. Trypanosoma have flagella, Paramaecium have a gullet that opens to the outside of the cell surface, and Plasmodium forms spores in its life-cycle.

Puccinia is a fungus which causes rust of wheat.

Thermoacidophiles are the archaebacteria found in hot springs.
