A food vacuole of Amoeba is analogous to

Options

A. sweat gland of mammals
B. typhlosole of earthworms
C. gastrovascular cavity of Hydra
D. nephrons of frog

Answer

To determine what the food vacuole of Amoeba is analogous to, we need to analyze the function of the food vacuole and compare it to the options provided.

### Step-by-Step Solution:

1. **Understand the Function of the Food Vacuole in Amoeba**:
- The food vacuole in Amoeba is responsible for digestion. When Amoeba captures food, it forms a food vacuole that contains digestive enzymes. These enzymes break down the food, allowing the organism to absorb nutrients.

2. **Examine the Options**:
- **Option 1: Sweat gland of mammals**: This option is incorrect as sweat glands are involved in thermoregulation and excretion, not digestion.
- **Option 2: Typhlosol of earthworms**: While the typhlosol increases the surface area for absorption, it does not directly perform digestion, making this option incorrect.
- **Option 3: Gastrovascular cavity of Hydra**: This is the correct option. The gastrovascular cavity serves a similar function to the food vacuole in Amoeba, as it is involved in digestion. The Hydra uses its gastrovascular cavity to digest food after capturing it with its tentacles.
- **Option 4: Nephrons of frog**: Nephrons are involved in excretion and osmoregulation, not digestion, so this option is also incorrect.

3. **Conclusion**:
- After analyzing the functions of the food vacuole and comparing it to the options, we conclude that the food vacuole of Amoeba is analogous to the gastrovascular cavity of Hydra, as both are involved in the digestion process.

### Final Answer:
The food vacuole of Amoeba is analogous to the gastrovascular cavity of Hydra (Option 3).
