Quick Answer: Which Is The Second Smallest Cell In Human Body?

Which blood cell is the smallest?

PlateletsPlatelets are the smallest of the three major types of blood cells..

What size 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.

What is the smallest cell in the human body?

spermThe 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.

Which is the second largest cell?

In animal cell Mitochondria is second largest cellular organelle, but Chloroplast(Plastids) are much larger than Mitochondria. So in Plants, Chloroplast becomes second largest organelle and third largest organelles of plant cell is thus Mitochondria.

Who is the founder of cell?

Robert HookeInitially 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 is the smallest animal cell?

MycoplasmaThe 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.

Which is the largest organelle in cell?

nucleusThe nucleus, the largest organelle in eukaryotic cells, is surrounded by two membranes, each one a phospholipid bilayer containing many different types of proteins. The inner nuclear membrane defines the nucleus itself.

What is the biggest cell in the female human body?

ovumThe 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.

What is the second largest cell in the human body?

The ovum also called egg cell is the reproductive cell in the female body. Ovum is 20 times bigger than the sperm cells and has a diameter of about 0.1 mm.

Which is the longest cell?

Nerve cells- 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 largest cell in our human body?

ovumThe human egg (ovum) is the largest cell in the body and a nerve cell is the longest cell in the human body.

Which neuron is the longest?

The longest axons in the human body are those of the sciatic nerve, which run from the base of the spinal cord to the big toe of each foot. The diameter of axons is also variable. Most individual axons are microscopic in diameter (typically about one micrometer (µm) across).

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 smallest cell in the female body?

The ovum also called egg cell is the reproductive cell in the female body. Granule Cellof the Cerebellum is the smallest cell of the human body which is approximately 4 micrometer to 4.5 micrometer in size.

Is a cell the smallest living thing?

The cell is the smallest structural and functional unit of living organisms, which can exist on its own. Therefore, it is sometimes called the building block of life. Some organisms, such as bacteria or yeast, are unicellular—consisting only of a single cell—while others, for instance, mammalians, are multicellular.

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.

What is the life span of RBC?

approximately 120 daysHuman red blood cells are formed mainly in the bone marrow and are believed to have an average life span of approximately 120 days.
