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.
A. It controls cellular activities
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.
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.
A. Store fluid and waste within a cell.
A:B: Inorganic matterInternal structures C:D: BothNeither #8 ___________ help an organism to obtain energy, get rid of waste, grow, and reproduce.
B. Internal structures
A:B: PlantAnimal #9 Photosynthesis occurs in what type of cell? C:D: MitochondriaVacuole
A:B: Neither a plant or animal Plant C:D: AnimalPlant & animal #10 These cells would most likely belong to a _________.
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?
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?
C. Cell membrane
A:B: Cell membraneMitochondria C:D: Chloroplastnone of these #13 The cell structure responsible for producing food in a plant. (F) In the diagram.
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?
A. Nerve cell
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?
