A2.2.1 Cells as the basic structural unit of all living organisms

What does the cell theory state about the composition of living organisms?

All living organisms are composed of one or more cells.

According to cell theory, what is the basic unit of structure and function in all organisms?

The cell is the basic unit of structure and function in all organisms.

How do new cells arise according to cell theory?

New cells arise only from the division of pre-existing cells.

What type of reasoning is used to make predictions based on cell theory?

Deductive reasoning.

What is deductive reasoning?

Starting from a general principle and applying it to specific cases.

Give an example of deductive reasoning using cell theory.

If all living things are made of cells, and a newly discovered object is alive, then it must be composed of cells.

How has cell theory been tested?

Repeatedly across diverse organisms.

What does the repeated testing of cell theory allow scientists to do?

Make deductive predictions about new discoveries.

What is the significance of cell theory in scientific inquiry?

It generates predictions from established theories, a key process in scientific inquiry.

List the three core statements of cell theory.

All living organisms are composed of one or more cells.

The cell is the basic unit of structure and function in all organisms.

New cells arise only from the division of pre-existing cells.

How does cell theory demonstrate the use of deductive reasoning in science?

By applying the general principle that all living things are made of cells to specific cases, such as newly discovered living objects.

What is the basic structural unit of all living organisms?

The cell.

What does the cell theory imply about the origin of cells?

Cells originate only from the division of pre-existing cells.

Why can scientists trust predictions made from cell theory?

Because it has been repeatedly tested and confirmed across diverse organisms.

What is the relationship between cell theory and new scientific discoveries?

Cell theory guides scientists to predict characteristics of new living organisms based on established principles.

What is the first statement of the cell theory?

All living organisms are composed of one or more cells.

What is the second statement of the cell theory?

The cell is the basic unit of structure and function in all organisms.

What is the third statement of the cell theory?

New cells arise only from the division of pre-existing cells.

How does deductive reasoning help in understanding cell theory?

It allows scientists to apply general principles of cell theory to specific cases to make predictions.

What does the cell theory say about the function of cells?

Cells are the basic unit of function in all organisms.

What is the importance of the cell as a unit in biology?

It is the fundamental building block of all living organisms, both structurally and functionally.

How does cell theory support the idea that life is continuous?

Because new cells arise only from pre-existing cells, life continues through cell division.

What is a key process in scientific inquiry demonstrated by cell theory?

Using deductive reasoning to generate predictions from established theories.
