Question

Which of the following organisms is correctly matched with its kingdom?

• A. Amoeba - Plantae
• B. Euglena - Fungi
• C. Paramecium - Protista
• D. Nostoc - Animalia

Hint:

*Key concept:* Organisms in Protista are often unicellular and do not fit neatly into other kingdoms.

Answer 1

The Correct Option is C

To address the issue, it is necessary to understand the various biological classification kingdoms and determine the kingdom to which each organism belongs.

1. Defining Biological Kingdoms

Scientists categorize all living entities into groups known as kingdoms based on their distinct traits. The primary kingdoms are:

• Plantae: Encompasses all plant life, capable of autotrophic nutrition via photosynthesis.
• Animalia: Comprises all animals, which obtain sustenance by consuming other organisms.
• Fungi: Includes organisms like mushrooms, molds, and yeast, which acquire nutrients by external digestion.
• Protista: Primarily unicellular organisms that do not fit definitively into the plant, animal, or fungal categories.
• Monera: Consists of bacteria and cyanobacteria (blue-green algae), which are primitive unicellular organisms lacking a membrane-bound nucleus.

2. Organism Analysis:

• Amoeba: A unicellular organism that exhibits motility through the extension of pseudopodia. As it lacks plant-like characteristics, it is not classified under Plantae. Amoeba is categorized within Protista.
• Euglena: Euglena is a unicellular organism possessing both photosynthetic capabilities similar to plants and motility akin to animals. Due to its dual characteristics and unicellular nature, it is assigned to Protista, not Fungi.
• Paramecium: Paramecium is a unicellular organism that utilizes cilia, hair-like appendages, for locomotion. It correctly belongs to the kingdom Protista.
• Nostoc: Nostoc is a form of blue-green algae (cyanobacteria), identified as a simple organism devoid of a nucleus. It is classified under the kingdom Monera, not Animalia.

3. Summary:

From the provided pairings, only Paramecium - Protista represents a correct classification.

Final Determination:

The correctly identified pair is Paramecium - Protista.
