Structures that are found outside of a plant or animal.

Structures that are found outside of a plant or animal.

• A. External Structure
• B. Internal Structure
• C. Organ
• D. Tissue

Answer: (A)

This question is about structures you can see on the outside of a plant or animal. External structures are the parts that are on the outside, like the leaves, stems, and flowers of a plant or fur, skin, and claws of an animal. These outside parts help protect the organism and interact with its surroundings. The other options describe things inside the body. An organ is a group of tissues working together inside the organism, and a tissue is a group of similar cells that work together inside. So they are not found outside the plant or animal; they are internal. That’s why the outside-facing term fits best.
