The correct Answer is:
To solve the question regarding what the seed of Pinus contains, let's analyze each option step by step: 1. **Understanding the Components of a Pinus Seed**: - The seed of Pinus (a type of conifer) is composed of several important structures. These include the embryo, endosperm, and perisperm. 2. **Analyzing Option (a)**: - **Parent sporophyte is form of perisperm**: - The perisperm is a tissue that provides nourishment to the developing embryo and is derived from the parent sporophyte. This statement is true. 3. **Analyzing Option (b)**: - **Endosperm as gametophyte**: - The endosperm in Pinus seeds is indeed a gametophyte tissue. It is formed from the fertilization of the polar nuclei and provides nutrition to the embryo. This statement is also true. 4. **Analyzing Option (c)**: - **Embryo as future sporophyte**: - The embryo in the seed of Pinus represents the future sporophyte generation. It will develop into a new plant. This statement is true as well. 5. **Analyzing Option (d)**: - **All the above**: - Since all the previous statements (a, b, and c) are true, option (d) which states "all the above" is also true. 6. **Conclusion**: - Therefore, the correct answer to the question is (d) All the above. ### Final Answer: (d) All the above
