Explanation / Answer

1. ANS: E. none of the above.

Explanation: Archaea have more complex RNA polymerases than Bacteria, similar to Eucarya. Unlike bacteria, archaea cell walls do not contain peptidoglycan. Archaea havedifferent membrane lipid bonding from bacteria and eukarya. There are genetic differences.

2. ANS: D. Spirillum

Explanation: A bacterium having a slightly curled or spiral-shaped cylinder is called a spirillum (spiral)

3. ANS: E. Vibrio

Explanation: If a bacterium is rod shaped with a gentle curve then it is vibrio

.4. ANS: A. Bacillus

Rod/Bacillus: A cell that is cylindrical. They are also quite varied in their actual form. They can be blocky, spindle-shaped, round-ended, long and threadlike (filamentous), or even club-shaped or drum-stick shaped.

5. ANS: The spike in a viral capsid composed mainly with carbohydrates and in some virus spike is composed with a glycoprotein.

6. ANS: All tapeworms are hermaphroditic and each segment contains both male and female organs. a hermaphrodite is an organism that has reproductive organs normally associated with both male and female sexes.

7. ANS: Chemotropism - plant movement in response to a chemical substance.

Ex: The growth of the pollen tube toward the substances secreted by the stigma and style and on to the ovule or embryo sac.
