No. Humans are made of billions if not trillions of cells that work together to form all of the systems in your body such as skin, the brain, blood and organs. These cells also are not the same type of cell, for example, a skin cell differs from a red blood cell as well as a brain cell.
But each person can be said to begin from one, single cell that results from the merging of ovum and sperm.
Yes, it is known as a zygote.
Single cell organisms still exist because populations evolve, rather than entire species. Additionally, if an organism is fit in it's environment, it is not pressured into evolving.
Eukaryotes have a true nucleus and prokaryotes have no nucleus. Eukaryptes also have a cell membrane and reproduce by meosis. Eukaryotes are also animals, plants, fungi and protists. Eukaryotic organisms can either be single-celled or multi-celled. Prokaryotes are bacteria.
That is not true. Plant cells have cell walls. Animal cells have cell membranes, but no cell walls.
Only organisms reproducing by the assexual process of cloning.
Plants, algae, fungi and bacteria all have cell walls. Animal cells do not have cell walls. Plants have cell walls made of cellulose, hemicellulose and pectin. In true fungi they are usually made of chitin, in algae they are made of a polysaccharide (like cellulose) or a glycoprotein, and bacteria have a peptidoglycan wall.
depends on what kind of single cell you are talking about. if it a single cell in bacteria, then yes, it does, but a single cell in the human body, I'm not so sure of that
True
yes it's true, every human being starts out as a single cell which is called a zygote.
Organisms such as bacterias that has no true nucleus.
True
TRUE
ummmmmmmmmmmm
true...
Partially, yes.
No. According to cell theory, the cell is the basic unit of all living things - therefore all living things are made of cells (some are made of a single cell, these are known as unicellular organisms).
No, bacteria cell walls is made up of peptidoglycan also called murein.
no, if that were true we would all still be a single cell
