Unit 1: Investigating Cell Structures & Functions

Nesting dolls are a set of hollow, wooden toys that have the same shape. Smaller nesting dolls fit inside larger dolls so that all smaller dolls fit into the largest doll when completely assembled. Students were asked to use nesting dolls to model the levels of organization from the smallest to largest structure.

Which model best demonstrates the levels of organization in plants and animals?

•

What kind of cell is represented by the diagram shown above?

• animal

• plant

• bacteria

• virus

Which structures identify the type of cell shown in the above diagram?

• I, II, V

• I, IV, V

• I, III, IV

• I, II, IV, V

Students observed cells under the microscope. They observed that the cells had a cell wall, cell membrane, nucleus, and many chloroplasts.

Which observation helps students identify the type of cell observed?

• The presence of a nucleus means the cells are from a plant.

• The presence of a cell membrane means that the cells are from an animal.

• The presence of chloroplasts means that the cells are from a plant.

• The presence of a cell wall means that the cells are from an animal.
