CASE BASED STUDY QUESTIONS

 

33

Read the following passage and answer the questions below:

A group of students collected water from a stagnant pond. Under the microscope, they observed green, unicellular organisms with a well-defined nucleus, cell wall, and flagella. These organisms performed photosynthesis and showed both plant-like and animal-like characteristics.

 

1. Identify the group and kingdom to which these organisms belong.

2. Justify why these organisms cannot be classified as plants.

3. Explain how such organisms exhibit dual characteristics.

4. What are the limitations of the five-kingdom system in classifying such organisms?

5. Name the photosynthetic pigment found in these organisms.

4

34

Read the following passage and answer the questions below:

Scientists exploring hot springs discovered unicellular, prokaryotic organisms that could survive extreme temperatures and acidic environments. These organisms lacked peptidoglycan in their cell walls and had unique enzymes.

 

1. Name and describe the group of organisms discovered.

2. List two features that differentiate them from typical bacteria.

3. Why are these organisms of evolutionary significance?

4. How do they contribute to biotechnology or industrial processes?

5. Name the organisms that produces biogas.
