Questions about the Cell Theory poster

What’s on the Cell Theory poster?

A definition and 5 facts worth remembering. Cell theory is the foundational idea of biology: cells are the basic unit of life, and all life is made of them. All living things are made of one or more cells.; The cell is the basic unit of structure and function.; All cells come from pre-existing cells.; Prokaryotes have no nucleus; eukaryotes do.; Bacteria are prokaryotes; plants, animals and fungi are eukaryotes.; A virus is not made of cells, which is one reason its status as 'alive' is disputed.. The third statement killed spontaneous generation — life does not arise from nothing.

Who is the Cell Theory poster for?

Cell Theory is filed under 9th Grade (ages 14–15), so it matches what that year asks a child to remember. It is equally useful to an older student revisiting science, and to the parent or teacher answering the question at the kitchen table.

When should you use the Cell Theory poster?
