Which type of immune cell is featured in the diagram above? - mast cell - neutrophil - macrophage - dendritic cell - VCE - SSCE Biology - Question 22 - 2020 - Paper 1

To identify the type of immune cell, it is necessary to analyze distinct characteristics associated with each option provided:

1. Mast Cell: Typically involved in allergic reactions and inflammation; they have granules rich in histamine.

2. Neutrophil: A type of white blood cell that is part of the innate immune system, primarily responsible for combating infections and inflammation. They usually have a multi-lobed nucleus.

3. Macrophage: These are phagocytic cells that can engulf and digest cellular debris and pathogens. They arise from monocytes and play a significant role in the immune response.

4. Dendritic Cell: Important antigen-presenting cells that help initiate the adaptive immune response, known for their long dendritic processes.

Based on the characteristics, the immune cell featured in the diagram above is a mast cell.
