because it is the cell wall
single-celled
multicelled
It is multi celled.
Multicellular
living things as different a single celled amoebas and multivalued humans both considered are both living and an organism must contain at least some Tye of living things.
"unicellular"
monera is a single-celled organism. it is very simple and small e.g. bacteria and cyanbacteria
Single-celled organisms grow by increasing in size and dividing into two daughter cells through binary fission. Multicellular organisms grow by increasing in cell number and size through cell division and differentiation, leading to the development of specialized tissues and organs.
One way that single-celled organisms are different from multi-celled organisms is in their complexity. Single-celled organisms consist of just one cell, while multi-celled organisms are made up of multiple cells organized into specialized tissues, organs, and systems. This allows multi-celled organisms to perform more complex functions and have greater structural and functional diversity.
Yes, all organisms in phylum nematoda are multicellular.
Most protista are unicellular, but not all are. Google Chlorophyta and Rhodophyta for examples of multicelled protista.
Cells in single-celled organisms function independently and carry out all life processes on their own, while cells in multi-celled organisms are specialized to perform specific functions. Multi-celled organisms have different types of cells that work together to support the organism as a whole.
