Explanation:

• All plants are made up of cells. So, Canadian waterweed plants are made up of tiny units called cells.
• Plant cells are usually very small and need a microscope to be seen clearly. So, the statement “Each Canadian waterweed cell is big enough to see without the help of a microscope” is false.
• All living organisms (both the one 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.
• Plant cells are generally less than 0.25 millimeters long. So, “Each Canadian waterweed cell is less than 0.25 millimeters long” is a valid statement.

Answer:

• “Canadian waterweed plants are made up of tiny units called cells.”
• “Each Canadian waterweed cell is less than 0.25 millimeters long.”
