The correct Answer is:
To determine the incorrect statement regarding the maize plant, let's analyze each statement step by step. ### Step-by-Step Solution: 1. **Statement I: "It is a monoecious plant with dioecious inflorescences."** - **Analysis:** The term "monoecious" means that a single plant has both male and female reproductive structures. However, maize (Zea mays) produces unisexual flowers, meaning it has separate male (tassels) and female (ears) flowers on the same plant. Therefore, this statement is incorrect as it contradicts the definition of monoecious plants. 2. **Statement II: "It has both fibrous and adventitious roots."** - **Analysis:** Maize primarily has a fibrous root system. Adventitious roots are roots that grow from non-root tissues, typically seen in some other plants (like certain types of grasses or climbing plants). Maize does not have adventitious roots, making this statement incorrect as well. 3. **Statement III: "Seed coat and fruit wall remain fused in its fruits."** - **Analysis:** In maize, the seed coat (pericarp) and the fruit wall are indeed fused together. This is characteristic of grains, including maize. Therefore, this statement is correct. 4. **Statement IV: "Feathery stigmas are seen in its gynoecium."** - **Analysis:** The female flowers of maize have feathery stigmas that help in capturing pollen. This statement is also correct. ### Conclusion: - The incorrect statements are **I** and **II**. However, since the question asks for the incorrect statement and not for all incorrect statements, the most notable incorrect statement is **I**. ### Final Answer: The incorrect statement regarding the maize plant is **I**: "It is a monoecious plant with dioecious inflorescences." ---
