In Albugo the food reserve is mostly

Options

A. Glycogen
B. Volutin granules
C. Protein granules
D. Fat.

Answer

**Step-by-Step Solution:**

1. **Identify the Organism:** The question asks about Albugo, which is a genus belonging to the class Oomycetes and the family Albugenaceae.

2. **Understand the Characteristics of Albugo:** Albugo is an obligate parasite that primarily affects cruciferous plants such as turnip, mustard, radish, cabbage, and cauliflower. It causes a disease known as white rust disease, characterized by shiny white patches or pustules on the infected plants.

3. **Determine the Food Reserve Material:** The food reserve material in Albugo is primarily in the form of glycogen bodies and oil drops.

4. **Evaluate the Options:**
- **Option 1: Glycogen** - This is correct as Albugo contains glycogen bodies as part of its food reserves.
- **Option 2: Volatile granules** - This is incorrect; these granules are associated with Saccharomyces and not Albugo.
- **Option 3: Protein granules** - This is also incorrect; Albugo does not store food in the form of protein granules.
- **Option 4: Fats** - This is incorrect as well; while oil drops are mentioned, they are not classified as fats in the context of food reserves.

5. **Conclusion:** The correct answer to the question is **Option 1: Glycogen**, as it accurately reflects the food reserve material found in Albugo.
