An attribute found in plants but not animals is(1) Metabolism(2) Sexual reproduction(3) Autotrophy(4) Asexual reproduction

To determine the correct answer to the question, we need to analyze the attributes found in plants compared to those in animals.

Analysis of Options

1. Metabolism: Both plants and animals have metabolism. It refers to the biochemical processes that occur within a living organism to maintain life, including converting food to energy.

2. Sexual Reproduction: Both plants and animals can reproduce sexually. Many plants and animals engage in sexual reproduction to create offspring.

3. Autotrophy: This is a unique attribute of plants. Autotrophic organisms produce their own food through processes such as photosynthesis, using sunlight, carbon dioxide, and water. Animals are heterotrophic, meaning they must consume other organisms for energy.

4. Asexual Reproduction: While asexual reproduction is common in some plants (such as through runners or cuttings), it is also present in various animal species (e.g., some reptiles and invertebrates).

Conclusion

Upon examining the options, the attribute that is specifically found in plants and not in animals is (3) Autotrophy.

Final Answer

(3) Autotrophy.
