5th Grade Science Review Unit 2

A student collects a sample of pond water in a jar to observe the microscopic algae that live in the water. The student then places a drop of the pond water on a microscope slide and observes it under a microscope. The drawings show what the student observed in the jar and on the slide.

Which claim is supported by evidence in the drawings?

• The student observed microscopic algae only on the slide because algae grow larger when placed on a microscope slide.

• The student observed microscopic algae only on the slide because all of the algae cells were removed from the pond water on the microscope slide.

• The student observed microscopic algae only on the slide because algae cells are too small to be seen without magnification by a microscope.

• The student observed microscopic algae only on the slide because the water in the jar was too cloudy to see the algae.

The pictures show two views of the same plant using a microscope and a magnifying glass.

Which of the following would be the best tool to use to identify the plant?

• The microscope, as it zooms in to show the structures inside the cells

• The magnifying glass, as it zooms in to show the structures inside the cells.

• The microscope, as it zooms out far enough to allow the whole plant to be seen.

• The magnifying glass, as it zooms out far enough to allow the whole plant to be seen.

Ethan holds a leaf in his hand. He describes it as green, shiny, and smooth. Then, he looks at the leaf under a microscope and under a magnifying glass. The pictures show what Ethan sees.

Which claim can Ethan make about magnification?

• Magnification makes it easier to see the small details of an object.

• Magnification makes the details of an object appear smaller than they really are.

• Magnification makes it easier to see the shape of a whole object.

• Magnification makes the shape of objects appear smaller than they really are.

Devon looks at a leaf through a microscope. Michael looks at the same leaf using a magnifying glass. What can Devon see that Michael cannot?

• Devon can see the cells of the leaf, but Michael cannot.

• Devon can see the color of the leaf, but Michael cannot

• Devon can see the texture of the leaf, but Michael cannot.

• Both Devon and Michael can see the cells and color of the leaf.

The picture shows cells under a microscope.

Which of the following statements is true?

• The cells have a nucleus so they are bacteria.

• The cells have cytoplasm so they are animal cells.

• The cells have chloroplasts so they are plant cells.

• The cells have membranes so they must be plant cells
