10 C. Cells

11 A:B: It gives the cell shape and support C:D: Both of theseNone of these It controls cellular activities #5 The nucleus in a cell contains chromosomes made of DNA material. What is the function of this nucleus? (D) In this diagram.

12 A. It controls cellular activities

13 A:B: MitochondriaGlucose C:D: ChloroplastsVacuoles #6 What are the small green structures in plants that trap energy from the sun and allow it to produce its own food? (F) In this diagram.

14 C. Chloroplasts

15 A:B: Stores fluid and waste within a cell Produces energy in a cell C:D: Both Neither #7 What is the function of the vacuole within a cell? (A) In this diagram.

16 A. Store fluid and waste within a cell.

17 A:B: Inorganic matterInternal structures C:D: BothNeither #8 ___________ help an organism to obtain energy, get rid of waste, grow, and reproduce.

18 B. Internal structures

19 A:B: PlantAnimal #9 Photosynthesis occurs in what type of cell? C:D: MitochondriaVacuole

20 A. Plant

21 A:B: Neither a plant or animal Plant C:D: AnimalPlant & animal #10 These cells would most likely belong to a _________.

22 D. Plant

23 A:B: MitochondriaNucleus C:D: Vacuolenone of these #11 In this diagram, which organelle indicates the part of the cell that contains most of the cells DNA?

24 B. Nucleus

25 A:B: MitochondriaNucleus C:D: Cell membranenone of these #12 In this diagram, which organelle indicates the part of the cell that separates the interior of the cell from its environment?

26 C. Cell membrane

27 A:B: Cell membraneMitochondria C:D: Chloroplastnone of these #13 The cell structure responsible for producing food in a plant. (F) In the diagram.

28 C. Chloroplasts

29 A:B: Nerve cellBone cell C:D: Muscle cellBlood cell #14 The cell in this picture is long because its function is to transport messages from one place to another. What kind of cell is this?

30 A. Nerve cell

31 A:B: Nerve cellBone cell C:D: Muscle cellBlood cell #15 The cells in this picture are narrow in the center Because their function is to transport oxygen to other cells. What kind of cell is this?
