Solution

The characteristics of macrophages are:

  1. They are phagocytes: This is true. Macrophages are a type of white blood cell that engulfs and digests cellular debris, foreign substances, microbes, and cancer cells in a process called phagocytosis.

  2. They have a regular shape: This is false. Macrophages do not have a regular shape. They are amorphous, meaning they can change their shape to move around and engulf foreign substances.

  3. They kill microorganisms: This is true. Macrophages are an important part of the immune system and their main job is to locate and 'eat' particles such as bacteria, viruses, fungi, and parasites.

  4. They are small cells: This is false. Macrophages are relatively large cells. They are larger than most other immune cells.
