Miracidium gives rise to

Options

A. sporocyst after entering snail
B. sporocyst in contact with aquatic vegetation
C. Redia after entering snail
D. Redia in contact with aquatic vegetation .

Answer

To answer the question "Miracidium gives rise to," we need to follow the life cycle of the Fasciola, also known as the liver fluke, which is a type of Platyhelminthes. Here’s a step-by-step breakdown of the process:

### Step 1: Understanding Miracidium
- **Definition**: Miracidium is the first larval stage of the Fasciola, which is a digenetic parasite. It is released from the primary host (sheep or goat) into the environment.

### Step 2: Entry into the Snail
- **Process**: After exiting the primary host, the Miracidium seeks out and enters the body of a suitable secondary host, which is typically a garden snail.

### Step 3: Development into Sporocyst
- **Transformation**: Once inside the snail, the Miracidium undergoes a transformation and develops into a sporocyst. This is a crucial stage in the life cycle of Fasciola.

### Step 4: Further Development
- **Subsequent Stages**: The sporocyst will eventually develop into other larval forms, including rediae, cercariae, and metacercariae, but the question specifically asks about what Miracidium gives rise to.

### Conclusion
- **Correct Answer**: Therefore, the correct answer to the question "Miracidium gives rise to" is **sporocyst after entering the snail**.
