Answer:
Cells are the basic building blocks of living things. ... Cells provide structure for the body, take in nutrients from food and carry out important functions. Cells group together to form tissues?, which in turn group together to form organs?, such as the heart and brain.
Answer:
The cell is the most basic unit of life. Each organism is made up of one or more cells. As we'll learn later, humans are made up of millions of cells. A discussion of how cells work and what they do for a living should be the first step.
These building components are known as biomolecules since they are found in living organisms. The architecture and functions of each of these basic building components are described in the sections that follow. We'll start with the basic components of a cell's structure. Regardless of their purpose or location in the body, all cells have the same characteristics and operations. Surprisingly, there are only four fundamental types of molecules in a cell. A cell is shown above, surrounded by instances of these molecular building blocks.
