The Largest Animal Cell is the ostrich egg. Animal cells lack plant-specific organelles such as chloroplasts, an organelle that performs photosynthesis, or cell walls that support a plant cell. The ostrich egg, which can measure up to 5.1 inches in width and weigh about 1.4 kg, is the largest known animal cell.

Largest Animal Cell

A fixed nucleus and other membrane-bound organelles, such as the Golgi apparatus, endoplasmic reticulum, and mitochondria, distinguish eukaryotic cells from prokaryotic cells. Prokaryotic cells do not have a fixed nucleus (instead, the area of the cytoplasm – called the nucleotide – contains the genetic material).

Organelles that are bound to membranes are also missing. Because all animals are multicellular, many cells work together to create the entire creature.

Facts about the Largest Animal Cell

These cells may have undergone extensive adaptation to perform a variety of tasks in complex creatures like humans. They are all made of human cells, but they are remarkably dissimilar in appearance and behavior.

  • Animal cells can be as large as a few millimeters or as small as a few microns. The human neuron, which is only 100 microns long, stands in stark contrast to this.
  • Animal cells can also vary in shape; some are smooth, while others are oval or rod-shaped.
  • Animal cells come in various varieties, each designed to perform specific tasks.
