Final answer:
The cell in the illustration is likely an animal cell because it lacks a cell wall, a feature that allows for varying shapes and specialization.
Step-by-step explanation:
The illustration likely shows an animal cell because it does not have a cell wall. Unlike plant cells, animal cells lack a cell wall, giving them the flexibility to take on different shapes and become specialized for various functions such as transmitting nerve impulses, in the case of nerve cells. While both animal and plant cells have cell membranes and a nucleus, it is the absence of a cell wall that is indicative of an animal cell. Furthermore, plant cells have additional structures that animal cells do not, such as chloroplasts, a large central vacuole, and specialized plastids.
