Which 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.
What is the smallest to largest cell?

What is the largest organelle in an animal cell?
The nucleus is the largest organelle within animal cells. The nucleus controls cell activity. It also contains the cell’s chromosomes. The chromosomes are made up of the genetic information (the DNA ) that makes you who you are.
Which is the smallest organelle of the cell?
The smallest organelle in the cell is the ribosome. The diameter of the ribosome is about 20 nm. It is made up of small and large subunits.
Which organelle is called suicidal bags of cell?
50 years ago, Christian de Duve introduced the term “suicide bags” to describe lysosomes (1), the organelles containing numerous hydrolases, which were, until the discovery of the ubiquitin-proteasome system, thought to be responsible for the major part of the intracellular turnover of proteins and other macromolecules …
How many cells die a day?
In humans, as many as 1011 cells die in each adult each day and are replaced by other cells. (Indeed, the mass of cells we lose each year through normal cell death is close to our entire body weight!)
Is egg a cell?
membrane and everything else inside is considered the cell, it can be said that it is a single cell. Then, the chicken egg deserves its reputation as the largest cell. If, however you consider the yolk and the albumen (the egg white), separate structures, then eggs are not a single cell.
How long can a human cell live?
The length of a cell’s life can vary. For example, white blood cells live for about thirteen days, cells in the top layer of your skin live about 30 days, red blood cells live for about 120 days, and liver cells live about 18 months.
Is acetabularia a prokaryote?
Acetabularia is a single-celled green photosynthetic algae which contain chloroplasts of the photosynthetic function. … Because of the presence of nucleus which is absent in prokaryote, these algae is classified in eukaryotes. hence algae Acetabularia is a unicellular eukaryote.
Is acetabularia unicellular?
Acetabularia is a genus of green algae in the family Polyphysaceae, Typically found in subtropical waters, Acetabularia is a single-celled organism, but gigantic in size and complex in form, making it an excellent model organism for studying cell biology.
