When we see any living organisms in the world, they are made of cells. Whether there is a single cell or a type of multicellular cell, they perform their functions. The term cells refer to the unit's structure present in the living organisms. These are the cells that are made with pre-existing cells.
Organisms
The organisms are classified into two parts: unicellular organisms and multicellular organisms.
1. Unicellular organisms
Unicellular organisms are organisms that are made of single cells.
Unicellular organisms are organisms that are made of single cells.
2. Multicellular organisms
Multicellular organisms are organisms that are made of different parts of cells.
These cells form the different parts and functions of the organism.
Example: Fungi, animals.
Cell's shape
The cell's shape is very different as it depends on the function type it is made of. And each shape of the cell will perform various functions.
Example: WBC (White Blood Cells) or Amoeba.
Elements of cell
The cell comprises three different components: the plasma membrane, nucleus, and cytoplasm. These are discussed below:
The plasma membrane is an envelope type that covers the whole cell parts.
The cell will get separated from the external environment due to the plasma membrane.
