A fifth grade student is studying two cells.

Which of the following BEST explains the difference in structure between the two cells.

• Both Cell A and B are plant cells because they both have nucleus and cell walls.

• Both Cell A and B are animal cells because they have a nucleus in the middle of the cell.

• Cell A is a plant cell because it has a rigid shape, whereas Cell B is an animal cell because it has a round shape.

• Cell A is an animal cell because it has a rigid shape, whereas Cell B is a plant cell because it has a round shape.

A student is studying a diagram of a cell. He can see a cell wall, cell membrane and a nucleus. Using these observations, what can the student conclude about the cell?

• It is likely from a tree.

• It is likely from a fish.

• It is likely from a spider.

A student in a 5th grade classroom was put to the test to identify the cells inside of a plant leaf. Which of the following ways is the best for the student to gather evidence?

• The student can use the naked eye and hold the plant close to their face and identify the cells.

• The student can use a hand lens and study the ridges on the leaf to identify the cells.

• The student can use a telescope to zoom in closely on the leaf and identify the cells.

• The student can use a microscope to zoom in closely on the leaf and identify the cells.

 Students went on a field trip to the Atlanta Zoo. Part of their field trip was to collect data on animals and classify them based upon how scientists classify animals.

Which of the following BEST describes how the student should develop a model to classify the animals?

• Animals 1, 3, and 4 will be classified together since they all lay eggs. Animal 2 will be classified separately since this animal has live birth.

• Animals 1 and 4 will be classified together since they have scales. Animals 2 and 3 will be classified together since they do not have scales.

• Animals 1 and 3 will be classified together since they both breathe with gills. Animals 2 and 4 will be classified together since they both breathe with lungs.

• Animals 1, 2, and 4 will be classified together since they have backbones. Animal 3 will be classified separately since this animal does not have backbones.
