WBC's engulf the invading germs by producing _____around the germs and digest the germs.

Explanation

**Step-by-Step Solution:**

1. **Understanding the Role of WBCs**: White blood cells (WBCs) are crucial components of the immune system. They help protect the body against infections by engulfing and digesting invading germs.

2. **Identifying the Process of Engulfing**: The process by which WBCs engulf germs is similar to how the single-celled organism Amoeba captures its food. WBCs can move out of blood vessels and reach the site of infection.

3. **Pseudopodia Formation**: WBCs utilize structures called pseudopodia, which are extensions of their cell membrane. The term "pseudopodia" means "false feet," allowing the WBCs to move and surround the invading germs.
