One may also ask, which is the largest known single cell?
Summary: Biologists used the world's largest single-celled organism, an aquatic alga called Caulerpa taxifolia, to study the nature of structure and form in plants. It is a single cell that can grow to a length of six to twelve inches.
How big can a cell grow?
The dozens of cell types that make up our body range in size and shape from small doughnut-shaped red blood cells that are just 8 micrometres across, to long skinny nerve cells that can grow to over one metre. In general, we grow to our full adult size via an increase in the number — not the size — of our cells.

Is a single cell alive?
Single cells “sense” their environment and “respond” but it is biochemically programmed by their DNA and the proteins which are produced from it. So yes, single cell bacteria and algae are alive, sperm and eggs are alive, and the single celled zygote that they produce at fertilization are also alive.How is algae used by humans?
Algae also provide the bulk of the Earth's oxygen supply through photosynthesis. But there is also a myriad of human uses for algae. We use algae for food, medicine, and even to combat climate change. Algae may even be used to produce fuel.Does bacteria have a nucleus?
Bacteria are considered to be prokaryotes, which means they do not have a nucleus and other membrane-bound organelles. Instead, the DNA is found in the nuceloid, a region with no membrane, or as a plasmid, a small circle of extra genetic information, floating right in the cytoplasm, the fluid that fills the cell.How complex is a single cell?

The system that synthesizes proteins is unbelievably complex, yet two thousand protein molecules are synthesized every second in every cell in your body, 24/7.What factor can stop normal cells from growing?
When aging cells stop dividing, they become “senescent.” Scientists believe one factor that causes senescence is the length of a cell's telomeres, or protective caps on the end of chromosomes. Every time chromosomes reproduce, telomeres get shorter. As telomeres dwindle, cell division stops altogether.What determines the minimum size of a cell?
Cell size is limited by a cell's surface area to volume ratio. A smaller cell is more effective and transporting materials, including waste products, than a larger cell. Cells come in many different shapes. A cell's function is determined, in part, by its shape.
