Explanation:

1. All living organisms, including plants like Canadian waterweed, are made up of cells. So "Canadian waterweed plants are made up of tiny units called cells" is true.
2. Canadian waterweed cells are relatively large and can be seen without a microscope, so "Each Canadian waterweed cell is big enough to see without the help of a microscope" is true.
3. All living organisms (both in micrograph and photograph) are made up of cells, so the statement "The organism shown in the micrograph is made up of cells, but the organism in the photograph is not" is false.
4. Canadian waterweed cells are typically less than 0.25 millimeters long, so "Each Canadian waterweed cell is less than 0.25 millimeters long" is true.

Answer:

• Canadian waterweed plants are made up of tiny units called cells.
• Each Canadian waterweed cell is big enough to see without the help of a microscope.
• Each Canadian waterweed cell is less than 0.25 millimeters long.
