Summarise what cells are in your own words.

Cells are the basic building blocks of all living things. They are the smallest units of life that can function independently. Cells come in many shapes and sizes, and their structures are specialized to perform specific tasks within organisms. They contain various components, such as a nucleus that holds genetic material, mitochondria for energy production, and other organelles that carry out different functions. Cells can also reproduce themselves through a process called cell division. In essence, cells are like tiny factories, each with a specific role in helping the organism survive.
