The correct Answer is:
To solve the question "All plants have two cotyledons in their seed, except," we need to analyze the options provided: pea, eucalyptus, sunflower, and orchid. ### Step-by-Step Solution: 1. **Understanding Cotyledons**: Cotyledons are the first leaves that appear from a seed during germination. Plants are classified into two main groups based on the number of cotyledons: dicots (two cotyledons) and monocots (one cotyledon). 2. **Identifying the Groups**: - **Pea**: Peas are dicots, which means they have two cotyledons. - **Eucalyptus**: Eucalyptus is also a dicot and has two cotyledons. - **Sunflower**: Sunflowers are dicots as well, having two cotyledons. - **Orchid**: Orchids belong to the monocot group, which means they have only one cotyledon. 3. **Conclusion**: Since the question asks for the plant that does not have two cotyledons, we identify that the orchid is the exception among the given options. 4. **Final Answer**: The correct answer is **Orchid**.
