A cell is the basic unit of life.
A cell is the smallest structure that can live and reproduce.
Cells grow and develop, reproduce and interact[1] with the environment.
Photosynthesis[2] is one of the most important biological[3] processes.
It allows plants to capture and use light as an energy source.
Photosynthesis is the process of converting light energy into chemical energy.
A virus is a small biological structure that attacks and enters cells.
Once inside a cell, a virus reproduces and makes many copies of itself.
Some diseases such as influenza[4] are viruses.
Bacteria are one-celled forms of life that are all around us.
Although they have a single-cell structure, they are very important.
Many bacteria are inside us and help us digest our food.
DNA is a complex molecule[5] that stores information and can make copies of itself.
Nearly every cell in a person's body has the same DNA.
The information stored in DNA tells cells what to do and is necessary for reproduction.
