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. |
