The correct Answer is:
To solve the question regarding the two cells in the pollen released by the majority of angiosperms, we can follow these steps: ### Step-by-Step Solution: 1. **Understanding Pollen Structure**: - Pollen grains in angiosperms typically consist of two main types of cells when they are released. 2. **Identifying the Cells**: - The two cells in the pollen are the **vegetative cell** and the **generative cell**. - The vegetative cell is larger and contains more cytoplasm, which is rich in nutrients. - The generative cell is smaller, spindle-shaped, and floats within the vegetative cell's cytoplasm. 3. **Function of the Cells**: - The vegetative cell is responsible for forming the pollen tube during fertilization. - The generative cell, which can divide mitotically, eventually forms two male gametes. 4. **Evaluating the Options**: - Option A: Gamete and generative cell - Incorrect. - Option B: Vegetative cell and tube nucleus - Incorrect. - Option C: Two male gametes - Incorrect. - Option D: Vegetative cell and generative cell - Correct. 5. **Conclusion**: - Therefore, the correct answer is that in the majority of angiosperms, the pollen is released in a two-celled stage consisting of the **vegetative cell** and the **generative cell**. ### Final Answer: The two cells are the **vegetative cell and generative cell**. ---
