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.
  • 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 behaviour.
  • Animal cells can be as large as a few millimetres 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.


Which is the largest animal cell?

The largest animal cell is the ostrich egg. Plant-specific organelles, such as chloroplasts, which perform photosynthesis, and cell walls, which support a plant cell, are absent from animal cells.
