The correct Answer is:
To determine the correct statement regarding slime molds, we need to analyze the characteristics of slime molds and the options provided. Here’s a step-by-step solution: ### Step 1: Understand the Classification of Slime Molds - Slime molds belong to the kingdom Protista. - They are eukaryotic organisms, meaning their cells have a nucleus and other organelles. **Hint:** Remember that slime molds are classified under Protista due to their eukaryotic nature. ### Step 2: Identify the Nature of Slime Molds - Slime molds are primarily unicellular but can aggregate to form a multicellular structure known as plasmodium. - The term "mold" is often associated with fungi, but slime molds are distinct in their classification. **Hint:** Focus on the fact that slime molds can exist as unicellular organisms but can also form aggregates. ### Step 3: Determine the Mode of Nutrition - Slime molds exhibit saprophytic nutrition, meaning they feed on dead and decaying organic matter. - They typically grow on decaying twigs and leaves, consuming the organic material. **Hint:** Saprophytic nutrition is key to understanding how slime molds obtain their food. ### Step 4: Analyze the Structure of Slime Molds - The plasmodium of slime molds is described as being "naked," which means it does not have a cell wall. - This structure allows for the movement and absorption of nutrients. **Hint:** The term "naked plasmodium" indicates the absence of a rigid cell wall, which is important for their function. ### Step 5: Examine the Reproductive Strategy - Slime molds reproduce by forming spores. - These spores are dispersed by air currents, allowing them to spread to new locations when conditions are favorable. **Hint:** Remember that the dispersal of spores is crucial for the survival and propagation of slime molds. ### Step 6: Evaluate the Options - Based on the characteristics discussed, we can evaluate the options provided in the question. - The correct statement should reflect the saprophytic nature, the structure of plasmodium, and the mode of spore dispersal. ### Conclusion - The correct statement regarding slime molds is that they are saprophytic, their plasmodium is naked without a cell wall, and their spores are dispersed by air. **Final Answer:** The correct statement is that slime molds are saprophytic, their plasmodium is naked without a cell wall, and spores are dispersed by air.
