Is virus the smallest cell?
Viruses are the smallest of all the microbes. They are said to be so small that 500 million rhinoviruses (which cause the common cold) could fit on to the head of a pin. They are unique because they are only alive and able to multiply inside the cells of other living things.
Which is the longest cell?

What is the largest single cell?
Biologists used the world’s largest single-celled organism, an aquatic alga called Caulerpa taxifolia, to study the nature of structure and form in plants. It is a single cell that can grow to a length of six to twelve inches.
Which is biggest animal cell?
Caulerpa taxifolia is the largest animal cell. it is an aquatic alga. Largest animal cell is ostrich eggs measuring about 170*135 mm in diameter.
Which is 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.
What is the biggest cell in the female human body?
