Question

Sally's teacher asked her to classify the organisms in a sample of pond water. One KEY feature can be seen that helped Sally rule out the kingdom Eubacteria. That was the presence of A) cilia. B) cell wall. C) organelles. D) chlorophyll.

Answer 1

I know you just toke this 4 days ago, but I still would like to say the answer! I just toke this test! The correct answer would be...  C) Organelles

Answer 2

Answer: The correct answer is -

C) Organelles.

Organelles are the subcellular compartments present in the eukaryotes (such as plants and animal cells). They serve specialised functions to the cell. For example-  Mitochondria is used to generate large amount of energy in the form of ATP.

Organelles are absent in the prokaryotes such as organisms belonging to the domain Eubacteria like E.coli.

Thus, 'presence of organelle' is the key feature that helped Sally to rule out the kingdom Eubacteria.
