The correct Answer is:
To determine the correct description of a starfish, we can analyze the options provided in the question step by step. ### Step-by-Step Solution: 1. **Understanding Starfish Anatomy**: - Starfish, also known as sea stars, belong to the phylum Echinodermata. They typically have a central disc and five or more radiating arms (or rays). - The body shape of a starfish is flat and has a radial symmetry, meaning that it can be divided into similar halves around a central axis. 2. **Evaluating the Options**: - **Option 1: Flat and Radiate**: This option suggests that starfish have a flat body structure and exhibit radial symmetry. This is accurate as starfish are indeed flat and have arms that radiate from the center. - **Option 2: Globular and Radiate**: This option implies that starfish have a rounded (globular) shape. This is incorrect as starfish do not have a globular shape. - **Option 3: Cylindrical with Repeatedly Branched Tentacles**: This option describes a body shape that is cylindrical and suggests the presence of branched tentacles. This is also incorrect as starfish do not have a cylindrical shape or branched tentacles. - **Option 4: Like a Spiny Ball**: This option suggests that starfish resemble a spiny ball. This is incorrect as starfish are flat and do not resemble a spiny ball. 3. **Conclusion**: - After evaluating all the options, the only correct description of a starfish is that it is "flat and radiate." Therefore, the correct answer is **Option 1: Flat and Radiate**. ### Final Answer: Starfish is **flat and radiate**.
