Visit a nearby park or a water body. Observe the water body and its surroundings. Identify ten organisms and classify them into kingdoms.
During a visit to a nearby park and its freshwater pond, I observed various organisms. In the water body, I identified Cyanobacteria belonging to Kingdom Monera, as they are prokaryotes with a primitive nucleus. I also found Amoeba, Paramecium, and Euglena, which belong to Kingdom Protista because they are unicellular eukaryotes.
Near damp soil and decaying logs, I observed a Mushroom. This organism belongs to Kingdom Fungi because it is a heterotrophic decomposer with a cell wall made of chitin.
In the park surroundings, I identified several plants. Grasses, Ferns, and a Rose bush all belong to Kingdom Plantae. These are multicellular eukaryotes that are autotrophic producers, possessing cell walls made of cellulose.
Finally, I observed an Ant crawling on a plant and a Frog near the water body. Both belong to Kingdom Animalia because they are multicellular eukaryotes without cell walls that depend on others for food, making them heterotrophic consumers.
Thus, the ten identified organisms are successfully classified into the five kingdoms based on their cell type, cell structure, level of organization, and mode of nutrition.
Explanation
The student uses the five kingdom classification framework and examples provided in the concept map (Fig. 12.5) to answer the activity question. By selecting organisms specifically mentioned in the text (Cyanobacteria, Amoeba, Paramecium, Euglena, Mushroom, Grasses, Ferns, Rose, Ant, Frog) and placing them in their respective kingdoms (Monera, Protista, Fungi, Plantae, Animalia), the student demonstrates an understanding of the classification criteria: cell type, level of organization, cell structure, and mode of nutrition.
Solution Steps
Step 1: Identify organisms from the water body (Cyanobacteria, Amoeba, Paramecium, Euglena) and classify them into Monera and Protista based on prokaryotic and unicellular eukaryotic features.
Step 2: Identify an organism from damp soil/decaying logs (Mushroom) and classify it into Fungi based on chitin cell wall and heterotrophic decomposition.
Step 3: Identify surrounding plants (Grasses, Ferns, Rose) and classify them into Plantae based on cellulose cell wall and autotrophic nutrition.
Step 4: Identify surrounding animals (Ant, Frog) and classify them into Animalia based on the absence of a cell wall and heterotrophic nutrition.
Step 5: Compile the ten organisms and summarize their classification based on the fundamental characteristics from the concept map.
