AEndosymbiosis
BPhagocytosis
CHydrolysis
DConjugation
Answer & Solution
Correct answer: B. Phagocytosis
1. Macrophages are a group of white blood cells that form part of the immune system.
2. A section of the macrophage plasma membrane invaginates, that is folds in, around a pathogen.
3. This process is known as phagocytosis or endocytosis.
4. Conjugation is a bacterial exchange of genetic material through pili, so it names an unrelated process.
5. The engulfing process is phagocytosis.
