Single-cell organisms.

Single-cell organisms. Cells come in an amazing variety – single-cell organisms (like bacteria),

cells of the immune system, the world’s largest cell, animal cells, plant cells, Natural Killer cells, cells with XXX chromosomes, and even cells that we could make a reality TV show with, like Cell Survivor: Livin’ On The Edge (like Archaeans ).  Pick a specific differentiated (liver cell, cytotoxic T-cell, neuron) or single-cell species (Yersinia pestis) and describe what the cell does.
