Select the true statements out of the following.

All of the above.

The apothecium consists of the fungal component only (e.g. Cladonia), such apothecia are called lecideine type.

The lichens are curious because they are composite or dual organism.

Parmelia, Physica, Lecanora etc. have more highly developed apothecia called Lecanorine type in which both fungal and algal components are present.

Thermus aquaticus is a species of bacteria found living in the hot springs in Yellowstone National Park. Hot springs typically are areas characterized by low oxygen levels, low light levels and high concentrations of sulfur and calcium carbonate.

In what way do bacteria living in or near hot springs most likely make food?

Through the process of photorespiration by using oxygen and light energy to produce carbon dioxide.

Through the process of radiosynthesis by using gamma radiation and melanin to create energy for growth.

Through the process of chemosynthesis by combining hydrogen sulfide with oxygen and carbon dioxide to make carbohydrates.

Through the process of photosynthesis by using energy from the sun, water and carbon dioxide to make glucose.

None

12.

Which of the following is unicellular?

Rhizopus

Moss

Pinus

Euglena

None

13.

An algal culture is grown and two different species of protozoans A and C are inoculated into the culture which feeds on algae. For the time period during which algae is not acting as a limiting factor, protozoan A reproduces asexually once every hour and protozoan C reproduces one every 1.5 hours.

The most likely observation is

The algae will die off from the culture due to overfeeding.

The algae will rapidly evolve to avoid predation.

Both populations of protozoans will increase in size initially, but then Protozoan C will die off from the culture.

The protozoans will evolve to have a mutualistic relationship.

None

14.

A semi-parasite relationship between the algal and fungal components of a lichen is termed as

Predation

Parasitism

Helotism

None of the above

None

15.

It is difficult to make anti-viral drugs because

Viruses use the host cell as machinery to grow and divide.

Viruses are surrounded by protein coat.

Viruses are one of the borderline of living and non-living state

Viruses are very small in size.

None

16.

Highly resistant thick walled spores produced by bacterial cells during unfavourable conditions are called as

Zoospores

Heterocyst

Gemmules

Endospores

None
