The largest cell is ovum in the human body. The ovum also called egg cell is the reproductive cell in the female body.
What is the largest cell in the male human body?
The largest cell in the human male is considered to be Neuron or specifically motor neuron.It is also the longest cell in human body. The length of its axon is about 1 metres and has a diameter of 100 microns.
Is kidney cell the largest cell in human body?
Answer. Nerve cell is the longest cell in the human body.
Is RBC the smallest cell in human body?
Features. The Cerebellum’s Granule Cell is the smallest cell in the human body that is between 4 micrometres to 4.5 micrometres long. The RBC’s size also found roughly 5 micrometres. Most scientists suggest that sperm is the smallest cell in terms of volume.
Is sperm bigger than red blood cell?
Red blood cells are about 6 microns across – that’s 6 thousandths of a millimetre – but they are very easy to see. Sperm are smaller, at about 1 micron across, but longer (length about 25 microns).
Which is the longest cell?
– In the human body, the nerve cell is the longest cell. Nerve cells are also called neurons that are found in the nervous system. They can be up to 3 feet long.
What’s the smallest cell in the 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.
What is the smallest and largest cell?
The smallest cell is Mycoplasma (PPLO-Pleuro pneumonia like organims). It is about 10 micrometer in size. The largest cells is an egg cell of ostrich. The longest cell is the nerve cell.
What is the biggest cell in the female human body?
The ovum is one of the largest cells in the human body, typically visible to the naked eye without the aid of a microscope or other magnification device. The human ovum measures approximately 120 μm (0.0047 in) in diameter.
Who discovered the cell?
Initially discovered by Robert Hooke in 1665, the cell has a rich and interesting history that has ultimately given way to many of today’s scientific advancements.
Which blood cell is the smallest?
Platelets are the smallest of the three major types of blood cells.
- Platelets are only about 20% of the diameter of red blood cells. …
- Red blood cells are the most numerous blood cell, about 5,000,000 per microliter. …
- White blood cells are the largest of the blood cells but also the fewest.

Which blood cell is the smallest in size?
Platelets. Platelets, or thrombocytes, are very small, irregularly shaped clear cell fragments, 2–3 µm in diameter, which derive from fragmentation of megakaryocytes.
What is the life span of RBC?
Human red blood cells are formed mainly in the bone marrow and are believed to have an average life span of approximately 120 days.
Is Whale Sperm visible to human eye?
Better have a microscope, because sperm are far too tiny to see with the naked eye. How tiny? Each one measures about 0.002 inch from head to tail, or about 50 micrometers. Of course, what sperm lack in size they more than make up in sheer numbers.
How big is a sperm cell?
A human sperm cell consists of a flat, disc shaped head 5.1 µm by 3.1 µm and a tail 50 µm long. The tail flagellates, which propels the sperm cell (at about 1–3 mm/minute in humans) by whipping in an elliptical cone.
