Animal Cell Definition
An animal cell is a type of eukaryotic cell that lacks a cell wall. It has a true, membrane-bound nucleus along with other cellular organelles.
Animal cells range in size from a few millimetres to microscopic microns. The largest known animal cell is the ostrich egg, which can stretch over 5.1 inches across and weigh about 1.4 kilograms. This is in stark contrast to the neuron in the human body, which is just 100 microns across.
The shape of animal cells also varies, with some being flat, others oval or rod-shaped. There are also more intriguing shapes such as curved, spherical, concave and rectangular. Most of the cells are microscopic in size and can only be seen under the microscope.
As stated before, animal cells are eukaryotic cells with a membrane-bound nucleus. Furthermore, these cells exhibit the presence of DNA inside the nucleus. They also comprise of other organelles and cellular structures which carry out specific functions necessary for the cell to function properly.
