Question Bank for Grade 10 Biology

When cells are damaged, new cells are created by cell division. How does the cell theory support this fact?

• It states that all cells have a nucleus which divides.
• It states that all living things are made up of one or more cells.
• It states that cells come from previously existing cells.
•  It states that the basic units of structure and function are cells.

Which electron microscope would you use to see a bed bug in 3D, with a magnification of about 500,000X?

• Compound Light

• Scanning Electron (SEM)

• Dissecting

• Transmission Electron (TEM)

Which electron microscope provides details of a cell's internal structures?

• Scanning Electron Microscope (SEM)
• Transmission Electron Microscope (TEM)
• Compound Light Microscope

• Dissecting Microscope

Which type of microscope would you use to see the outside of a paramecium, without seeing much detail?

• Compound Light Microscope

• Scanning Electron Microscope (SEM)

• Dissecting Microscope

• Transmission Electron Microscope (TEM)

Cell theory states
1.  All living things are made of cells
2. Cells are the basic unit of structure and function to living things
3. ???

• All cells are prokaryotic

• All cells are produced from other cells

• All cells get rid of waste

• All cells need food and water

The cell theory states that the cell is the most basic unit of life, all organisms are made of cells, and all cells come from cells. What makes the cell theory a scientific theory?

• It is based on a scientific publication that is read by scientists worldwide.
• It is based on the work of many scientists and leads to accurate predictions.
• It is based on ideas that have been proven true and that are not subject to revision.
• It is based on preliminary evidence but sill needs to be confirmed with experiments.

Why has knowledge about the cell theory changed over the last few hundred years?

• Improvements in technology have provided more accurate data and new observations.

• Scientists are better at making inferences because they are smarter.

• Theories have been shown to be educated guesses.

• New cellular organelles have evolved to replace old organelles.

Which invention from the 17th century allowed for the development of modern cell theory?

• X-rays

• Computers

• Compound light microscope

• Scanning electron microscope (SEM)

The combined observations of Mattias Schleiden, Theodor Schwann and Rudolph Virchow resulted in the formation of the cell theory. Which of the following is not part of the cell theory?

• All cells contain a nucleus. 
• All cells come from other living cells.
• All living organisms are made of one or more cells
• Cells are the basic unit of structure and function of all living things.

A plant and an animal are both living things. According to the Cell Theory, what can you conclude about these two very different organisms?

• Plants have cells but animals do not.
• They are both made of one or more cells. 
• They both come from the same kind of cell.
• They both come from a non-living organism.
