Cycas has the embryo with two cotyledons. Yet it is not classified as dicotyledonous plant because:

Options

A. it looks like palm tree
B. it bears megasporophylls
C. its ovules are naked
D. it bears microsporophylls

Answer

**Step-by-Step Solution:**

1. **Understanding Cycas**: Cycas is a type of plant that has two cotyledons in its embryo. Cotyledons are the first leaves that appear from a germinating seed.

2. **Classification of Plants**: Plants are generally classified into two main groups based on their seed structure: dicotyledonous (dicots) and monocotyledonous (monocots). Dicots have two cotyledons, while monocots have one.

3. **Angiosperms vs Gymnosperms**: Dicots and monocots are part of a larger group called angiosperms, which are flowering plants. In contrast, Cycas is classified as a gymnosperm, which means it does not produce flowers and has naked seeds.

4. **Naked Ovule**: In gymnosperms like Cycas, the ovule is exposed or "naked" and not enclosed within a fruit. This is a key characteristic that differentiates gymnosperms from angiosperms.

5. **Conclusion**: Despite having two cotyledons, Cycas is not classified as a dicotyledonous plant because it is a gymnosperm, which is characterized by its naked ovule and lack of flowers.

**Final Answer**: Cycas has two cotyledons but is not classified as a dicotyledonous plant because it is a gymnosperm, which has naked ovules and does not produce flowers.
