Surface2/volume ratio3
The surface area is a squared function while volume is a cubic function. This means volume increases much faster than surface area and a cell could not preform it's functions of nutrient import and waste export if it grew too large and had this ratio too unfavorably large.
Yes
are made of more than one cell.
No. Organisms with more than one cell are called multicellular organisms, which include humans, dogs etc. Organisms with only one cell are called unicellular, or singled celled organisms, and this group includes protozoans, specific algae and some spores. Hope this helps!
Unicellular organisms have only one cell. They have a large surface area to volume ratio and rely on simple diffusion to meet their needs. Multicellular organisms have many cells. The cells are specialized and have a certain job to do.
one, all organisms are made of one or more cells. two, the cell is the basic unit of organization in organisms. three, all cell are made of other cells!
All animals are organisms. An organism is anything living that is made of at least one cell. The smallest being... "single-cell organisms" these contain only one cell and are microscopic.
they are called unicellular
No. Ants are multicellular organisms.
Unicellular organisms contain just one cell, example: amoeba, bacteria. Multicellular organisms are made up of more than one cell which includes everything other than the unicellular organisms.
No, not all organisms have more than one cell. Organisms can be unicellular (made up of a single cell) or multicellular (made up of multiple cells). Examples of unicellular organisms include bacteria and protists, while multicellular organisms include plants, animals, and fungi.
One cell These are all single cell organisms.
