Answer: (A)

Verified step by step guidance

1. Understand the structure of a seed: A seed typically consists of three main parts - the embryo, the seed coat, and the endosperm. The embryo includes structures such as the cotyledon, which is crucial for the seed's development.
2. Identify the role of the cotyledon: The cotyledon is a part of the embryo within the seed. It often serves as a food storage organ and can also be the first leaves that appear when the seed germinates.
3. Differentiate between seed parts and other plant structures: Petals, stamens, and chloroplasts are not parts of a seed. Petals are part of the flower, stamens are the male reproductive part of a flower, and chloroplasts are organelles found in plant cells responsible for photosynthesis.
4. Recognize the function of each option: Petals attract pollinators, stamens produce pollen, and chloroplasts conduct photosynthesis. None of these functions are related to the seed's structure or its initial growth.
5. Conclude that the cotyledon is the only option that is a part of a seed, as it is directly involved in the seed's development and germination process.
