Cells are the basic building blocks of life. It is hard for us now to imagine scientists not knowing about cells, but until microscopes were developed, they couldn’t be seen, let alone described or observed.
Technology and scientific discovery
The invention of the microscope in the early 17th century was key to the discovery of cells and to distinguishing different types of cells. Explore this further in History of microscopy – timeline.
Organisms and cells
In fact, all life forms are built from cells.consist of just a single cell, whereas our bodies are made up of approximately 75 trillion cells, divided into more than 200 different cell types.
Basic cells have an outer surface or plasma organelles (“little organs”) that carry out specific functions depending on the cell type., are filled with a substance called cytoplasm and contain
Bacteria cells are called what bacteria are. Plant and animal cells are called , and their DNA is contained within a specialised structure known as the ., and their is just floating around inside them. Find out more about
Cells are able to create copies of themselves by a process called division of a cell from one, to two, to four forms the basis of growth and development of all living things.. The
