Four students examined the cells and made the following observations: 
Student 1: Cell 1 is a plant cell because it has a cell wall
Student 2: Cell 2 is an animal cell because it has a nucleus
Student 3: Cell 1 is a plant cell because it has chloroplasts
Student 4: Cell 2 is an animal cell because it has a cell membrane
Who is correct?

• Student 1 and Student 2
• Student 2 and Student 3
• Student 1 and Student 3
• Student 2 and Student 4

Mrs. Smith's science class is examining cells under a microscope. Her students find the Elodea plant cells easily, but when looking at a cheek cell the outlines of the animal cells are hard to see. Why are animal cells harder to see than the plant cells?

• plant cells contain organelles, while animal cells do not

• plant cells are much larger than animal cells

• plant cells have cell walls, but animal cells do not

• plant cells are circular, but animal cells are rectangular

Scientists found a strange blob, buried under lots of dirt and rock. They had to decide if this blob is a living or nonliving thing. What would be a good way to find out?

• Melt it and see if it goes through a physical or chemical change.

• Test it in a lab to find out what atoms it is made of.

• Look at it under a microscope and look for cells.

• Poke at it with a stick to see if it moves.
