The correct Answer is:
To determine the optimal environmental conditions for the growth of Mucor on a piece of bread, we need to analyze each option provided in the question: 1. **Temperature of about 25°C (Option A)**: - Mucor typically thrives in warm conditions, and a temperature around 25°C is generally favorable for its growth. This temperature is close to room temperature, which is ideal for many fungi. 2. **Temperature of about 5°C (Option B)**: - This temperature is too cold for Mucor to grow effectively. Fungi generally do not thrive in cold conditions, and 5°C is more suitable for refrigeration, which inhibits fungal growth. 3. **Relative humidity of about 5% (Option C)**: - A relative humidity of 5% is very low and not conducive to the growth of Mucor. Fungi require a moist environment to thrive, and such low humidity would hinder their growth. 4. **Relative humidity of about 95% (Option D)**: - A relative humidity of 95% is ideal for the growth of Mucor. High humidity levels provide the moisture necessary for fungal spores to germinate and grow. 5. **A shady place (Option E)**: - Mucor prefers shady environments as direct sunlight can be detrimental to its growth. Fungi generally thrive in dark or shaded areas where moisture can be retained. 6. **A brightly illuminated place (Option F)**: - Bright light is not suitable for Mucor growth. Fungi typically do not grow well in brightly lit conditions as they prefer darker environments. Based on the analysis, the conditions that are essential for the optimum growth of Mucor on a piece of bread are: - Temperature of about 25°C (Option A) - Relative humidity of about 95% (Option D) - A shady place (Option E) Thus, the correct answer is **ADE (A, D, and E)**.
