Which cell is the smallest cell in human body?

The sperm is the smallest cell in human biology, but also one of the most complex. The egg meanwhile is the largest cell and similarly intricate. Looking further out into the natural world, the diversity of these sex cells, or gametes, is truly remarkable. Most species have two gametes, which we term male and female.

Which is the largest and smallest cell in human body?

Which is smaller RBC or sperm?

Most scientists suggest that sperm is the smallest cell in terms of volume. Sperm cell head measures about 4 micrometres in length, just slightly smaller than a red blood cell (RBCs).

Which is the longest cell in human body?

Neurons or nerve cells can be up to 3 feet long. A typical neuron has a cell morphology called soma, hair-like structures called dendrites and an axon. Neurons are specialized in conveying knowledge throughout the body. The sensory neurons, motor neurons, and interneurons are three types of neurons.
