The correct Answer is:
To identify the correct sequence for different stages of embryo development in dicots, we can break down the process into several key steps: ### Step-by-Step Solution: 1. **Zygote Formation**: The process begins with the formation of the zygote after fertilization. This is the initial stage of embryo development. 2. **Pro-embryo Stage**: After the zygote, the first stage of embryo development is the pro-embryo stage. During this stage, the zygote undergoes cell division. 3. **Globular Stage**: Following the pro-embryo stage, the next stage is the globular stage. In this stage, the embryo takes on a globular shape as the number of cells increases. 4. **Heart-shaped Stage**: The globular embryo then develops into the heart-shaped embryo. This stage is characterized by the formation of cotyledons, which gives the embryo a heart-like appearance. 5. **Mature Embryo**: Finally, the last stage is the mature embryo. At this stage, the structures known as the plumule (which will develop into the shoot system) and the radicle (which will develop into the root system) are formed. ### Correct Sequence: The correct sequence of stages in dicot embryo development is: - Globular embryo - Heart-shaped embryo - Mature embryo ### Conclusion: Thus, the correct answer is the fourth option: **Globular embryo → Heart-shaped embryo → Mature embryo**. ---
