The correct Answer is:
To solve the question "Pinus seeds are", we need to analyze the characteristics of Pinus seeds based on the provided options. Here’s a step-by-step solution: ### Step 1: Identify the type of seeds in Pinus Pinus is a genus of gymnosperms, which means that its seeds are not enclosed within a fruit. This characteristic indicates that Pinus seeds are "naked." **Hint:** Remember that gymnosperms have naked seeds, unlike angiosperms which have seeds enclosed in fruits. ### Step 2: Analyze the seed shape The shape of the seeds is also important. In the case of Pinus, the seeds are classified as orthotropous. This means that the embryo is straight and the micropyle is aligned with the hilum. **Hint:** Orthotropous seeds have a straight arrangement, which can be visualized as the seed lying flat with the micropyle and hilum in line. ### Step 3: Evaluate the options Now, we can evaluate the options provided: 1. Naked and Campylotropous 2. Naked and Anatropos 3. Naked and Orthotropous 4. Covered and Orthotropous Since we established that Pinus seeds are naked and orthotropous, we can eliminate options 1, 2, and 4. **Hint:** Look for the terms "naked" and "orthotropous" in the options to find the correct answer. ### Step 4: Conclusion The correct answer is option 3: Naked and Orthotropous. **Final Answer:** Pinus seeds are naked and orthotropous.
