Who is the father of cell?

The Nobel

laurate Romanian-American cell biologist George Emil Palade

is popularly referred to as the father of the cell. He is also described as the most influential cell biologist ever.

Are viruses living?


Viruses are not living things

. Viruses are complicated assemblies of molecules, including proteins, nucleic acids, lipids, and carbohydrates, but on their own they can do nothing until they enter a living cell. Without cells, viruses would not be able to multiply. Therefore, viruses are not living things.

Who named the cell?

In the 1660s,

Robert Hooke

looked through a primitive microscope at a thinly cut piece of cork. He saw a series of walled boxes that reminded him of the tiny rooms, or cellula, occupied by monks. Medical historian Dr. Howard Markel discusses Hooke’s coining of the word “cell.”

an egg cell of ostrich

. The longest cell is the nerve cell. The largest cell in the human body is female ovum. Smallest cell in the human body is male gametes, that is, sperm.

Do viruses have DNA?


Most viruses have either RNA or DNA as their genetic material

. The nucleic acid may be single- or double-stranded. The entire infectious virus particle, called a virion, consists of the nucleic acid and an outer shell of protein. The simplest viruses contain only enough RNA or DNA to encode four proteins.

Why are viruses not considered alive?

Finally, a virus isn’t considered living

because it doesn’t need to consume energy to survive

, nor is it able to regulate its own temperature.

How are viruses created?

Viruses may have

arisen from mobile genetic elements that gained the ability to move between cells

. They may be descendants of previously free-living organisms that adapted a parasitic replication strategy. Perhaps viruses existed before, and led to the evolution of, cellular life.

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.

Which is largest organ?


The skin

is the body’s largest organ.

Which is the smallest cell?

As of today,

the mycoplasmas

are thought to be the smallest living cells in the biological world (Fig. 1). They have a minimal size of approximately 0.2 micrometers, which makes them smaller than some of the poxviruses.
