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.
Which organisms have the smallest size of cells?
The size of the cell ranges from 0.5 micrometers to 100 micrometers. Mycoplasma gallicepticum, a parasitic bacterium is thought to be the smallest known organisms with the size from 0.2 to 0.3 micrometer, capable of independent growth and reproduction.
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.
What are the smallest cells in the blood?
Platelets are the smallest of the three major types of blood cells.
Is Sperm the smallest cell in the human body?
Sperm cells are among the smallest cells in the human body.
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 is the smallest virus in size?
Structures such as these are unique to the bacteriophages. Animal viruses exhibit extreme variation in size and shape. The smallest animal viruses belong to the families Parvoviridae and Picornaviridae and measure about 20 nm and about 30 nm in diameter, respectively.
What is the largest virus in the world?
The physically largest virus is Pithovirus sibericum, at 1.5 microns (or 1,500 nanometers) in length [2]. Though that might seem tiny, it is larger than some bacteria, and approximately half the width of a strand of spider web silk [3].
What is the largest and smallest virus?
The smallest double-stranded DNA viruses are the hepadnaviruses such as hepatitis B, at 3.2 kb and 42 nm; parvoviruses have smaller capsids, at 18-26 nm, but larger genomes, at 5 kb. It is important to consider other self-replicating genetic elements, such as satelliviruses, viroids and ribozymes.
Which animal is smallest in the world?
The Etruscan shrew (Suncus etruscus), also known as the Etruscan Pygmy Shrew and the White-toothed Pygmy Shrew, weighs only 0.04–0.1 oz (1.2–2.7 g). That makes it the world’s smallest mammal when measured by weight, but, at 1.4–2 in (36–53 mm), it loses out to the bumblebee bat for smallest in length.
What is the largest cell in the female 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 0.1 mm (0.0039 in) in diameter.

Is Whale Sperm the same size as human sperm?
Amazing, whales have some of the smallest sperm of all mammals. They vary from 50-75 microns, whereas human sperm are 40-90 microns long.
