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.
Who is the smallest cell?
Answer: A cell is described as the smallest, basic unit of life in charge of all the processes of life. The Cerebellum’s Granule Cell is the smallest cell in the human body that is between 4 micrometers to 4.5 micrometers long. The RBC ‘s size also found roughly 5 micrometers.
Is RBC smallest cell in human body?
The RBC ‘s size also found roughly 5 micrometers. The largest cell is ovum in the human body. The ovum also called egg cell is the reproductive cell in the female body.

Which blood cell is the smallest?
Platelets are the smallest of the three major types of blood cells.
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 cell is the longest?
– 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 is the longest cell in the world?
Answer. Answer: If talking of human body, largest cell is OVUM or egg cell owing to its diameter however nerve cells are the longest cell. And all over the world the largest and longest cell are the NERVE CELLS Giant Squid and Colossal Squid.
Which is the longest human body cell?
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.
Which blood cell is largest in size?
Monocytes are the largest cells of the blood (averaging 15–18 μm in diameter), and they make up about 7 percent of the leukocytes.
What is the largest cell in our human body?
The human egg (ovum) is the largest cell in the body and a nerve cell is the longest cell in the human body.
Which blood cell is known as scavenger?
White blood cells are called the natural scavengers.
What are the 7 types of blood cells?
Suspended in the watery plasma are seven types of cells and cell fragments.
- red blood cells (RBCs) or erythrocytes.
- platelets or thrombocytes.
- five kinds of white blood cells (WBCs) or leukocytes. Three kinds of granulocytes. neutrophils. eosinophils. basophils. Two kinds of leukocytes without granules in their cytoplasm.
What is the shape of RBC?
The shape of the human red blood cell is known to be a biconcave disk. It is evident from a variety of theoretical work that known physical properties of the membrane, such as its bending energy and elasticity, can explain the red-blood-cell biconcave shape as well as other shapes that red blood cells assume.
Which is smallest virus?
AAV is the smallest DNA virus with an average size of 20 nm.
Is virus a cell?
Viruses are not made out of cells. A single virus particle is known as a virion, and is made up of a set of genes bundled within a protective protein shell called a capsid. Certain virus strains will have an extra membrane (lipid bilayer) surrounding it called an envelope.
Which is largest virus?
With the discovery of Mimivirus — the largest, most complex virus currently known — these assumptions may need to be reevaluated. This giant virus has a much larger size and bigger genome than any other known virus.
