Living things I. Cells and review.

Biosphere refers to all the living things on Earth. From the smallest single-celled bacteria, to the huge blue whale. All of us share some characteristics, but there are also some features that make the difference.

Let's discover characteristics we share, but also the differences that exist among us. Because you are unique, right?

We are all made up of cells

Cells are the structural and functional unit of living things. This means we are built of cells (like little bricks); and it also means that all the things we do, depend on them (little machines that carry out functions). As we are not mushrooms, neither pines; there must be different cells according to the living thing in question.

Check this presentation about the different types of cells and their organelles.

Yeah... pictures are cool, but we live in a multi-dimensional universe, so let's check at least a 3D representation of a cell.

What is a cell?

Depending on their genetic material, cells are classified in prokaryotic and eukaryotic cells. Search on Google images pictures of each one. How do we find their DNA?

What do all cells have in common? Although prokaryotic and eukaryotic cells are different, they share 3 elements. Compare both cell types, and try to find out what they have in common.
