Pick up the wrong statement.A. Cell wall is absent in AnimaliaB. Protista have photosynthetic and heterotrophic modes of nutritionC. Some fungi are edibleD. Nuclear membrane is present in Monera |
|
Answer» Correct Answer - D (d) In Protista kingdom members exhibit both autotrophic as well as heterotrophic nutrition. Animal cells lack cell wall and there are a few fungi that are edible. Monera is the kingdom that contains unicellular organisma with a prokaryotic cell organisation, i.e. which lacks nuclear membrane and other membrane bound organelles. |

Protistan genome hasA. membrane bound nuleoproteins embredded in cytoplasmB. free nucleic acid aggregatesC. gene containing nucleoproteins condensed together in loose massD. nucleoprotein in direct contact with cell substance |
|
Answer» Correct Answer - A (a) Eukaryotic (e.g. protistan) genome is organised in the form of nucleus. It is differentiated into nuclear envelope, chromatin, one or more nucleoli and nucleoplasm. Nuclear DNA is linear, associated with histone proteins, A small quantity of DNA is also found in the plastids and mitochondria. In contrast, prokaryotic (bacterial) DNA is circular and lies frelly in the cytoplasm. |
