The correct Answer is:
To answer the question regarding the types of endosperm based on their mode of formation, we can break it down into the following steps: ### Step-by-Step Solution: 1. **Understanding Endosperm**: - Endosperm is a tissue that provides nutrition to the developing embryo in seed plants. It is formed after fertilization and plays a crucial role in seed development. 2. **Types of Endosperm**: - There are three main types of endosperm based on their mode of formation: - **Nuclear Endosperm**: - In this type, the primary endosperm nucleus (PEN) undergoes multiple rounds of division without the formation of cell walls. This results in a multi-nucleate condition where the cytoplasm contains several nuclei. - **Cellular Endosperm**: - Here, the divisions of the primary endosperm nucleus are followed by cytokinesis, which means that after each division, the cytoplasm divides to form individual cells. This leads to a cellular structure in the endosperm. - **Halobel Endosperm**: - In this type, the division of the primary endosperm nucleus is followed by transverse cytokinesis. This means that the nucleus divides, and then the cytoplasm divides in a way that results in a free nuclear condition, leading to a specific arrangement of cells. 3. **Conclusion**: - Based on the descriptions of these three types, we can conclude that all of them are valid types of endosperm based on their mode of formation. Therefore, the correct answer to the question is **D. All of them**.
