1 The organelle that digests food particles, wastes, cell parts, and foreign invaders 1.Vacuole 2.Lysosome 3.Cytoplasm 4.Ribosome

2 In plant cells, this stiff wall surrounds the cell membrane, giving the cell a rigid, boxlike shape. 1.Cell Wall 2.Cell Membrane 3.Vacuole 4.Nuclear Envelope

3 Thin, flexible barrier around a cell, it regulates what enters and leaves the cell 1.Cell Wall 2.Golgi Apparatus 3.Cell Membrane 4.Nucleus

4 The control center of the cell that directs the cell's activities; it contains the chemical instructions that direct all the cell's activities (DNA) 1.Vacuole 2.Ribosome 3.Cell Membrane 4.Nucleus

5 Cells that do not have a distinct nucleus are called: 1.Prokaryotic 2.Eukaryotic 3.Multicellular 4.Animal

6 The jellylike fluid that contains nutrients in a cell is the: 1.Cytoplasm 2.E.R. 3.Golgi Apparatus 4.Lysosome

7 Small organelles that are responsible for protein synthesis are the: 1.Nucleus 2.Ribosomes 3.Cytoplasm 4.Cell Membrane

8 The ‘powerhouse’ of the cell that generates the cell’s energy 1.Chloroplast 2.E.R. 3.Golgi Apparatus 4.Mitochondria

9 The organelle found in both animal and plant cells that is clear but contains dissolved nutrients is the: 1.Centriole 2.Chloroplast 3.Vacuole 4.Cell Membrane

10 Cells that have internal membranes surrounding specialized organelles are: 1.Bacteria Cells 2.Eukaryotic 3.Prokaryotic 4.Unicellular

11 Which of the following statements is false 1.All living things are made of cells. 2.Animal cells have a cell membrane and a cell wall. 3.Cells come from other cells. 4.Lysosomes are found only in animal cells.

12 To enter or leave a cell, substances must pass through 1.A microtubule 2.Golgi apparatus 3.Ribosome 4.Cell Membrane

13 The pancreas is an organ that creates the protein insulin. Which organelle in a pancreas cell packages insulin to be secreted out of the cell? 1.Golgi apparatus 2.Ribosome 3.Mitochondria 4.Nucleus 5.lysosome

14 What cell structure makes it possible for the internal environment of a cell to differ from the external environment? 1.Cell wall 2.Cell membrane 3.E.R. 4.cytoplasm

15 Which of the following are all present in animal cells 1.mitochondria, cell membrane, cell wall, cytoplasm 2.chloroplasts, cytoplasm, vacuole, nucleus 3.nucleus, cell membrane, mitochondria, cytoplasm 4.vacuole, cell membrane, nucleus, mitochondria

16 Centrioles are present in _____. 1.Animal cells only 2.Plant cells only 3.In both plant and animal cells 4.In neither plant nor animal cells

17 The 'Scavengers' or 'Digestive bags' of a cell are ____. 1.Chromosomes 2.Centrosomes 3.Lysosomes 4.Ribosomes

18 The network of endoplasmic reticulum is present in the ____. 1.Nucleus 2.Chromosome 3.Cytoplasm 4.Golgi apparatus

19 Centrioles are associated with ____________. 1.Digestion 2.Reproduction 3.Respiration 4.Cell division

20 Bacterial cells are prokaryotic; in comparison to a typical eukaryotic cell they would 1. be smaller. 2.have a smaller nucleus. 3.lack a plasma membrane. 4.have a greater variety of organelles.

21 Proposed that cells are produced by other cells 1.Robert Hooke 2.Rudolf Virchow 3.Schwann 4.Schleiden

22 All things are made of cells, -cell is basic unit of life, -new cells come from existing cells 1.Theodor Schwann 2.Robert Hooke 3.cell theory 4.Rudolf Virchow

23 Discovered that plants are made of cells 1.Theodor Schwann 2.Prokaryotic cells 3.cell theory 4.Matthias Schleidan

24 A 0.9% NaCl solution is isotonic to red blood cells. Which of these describes the results if red blood cells are placed into a 9% solution of NaCl? 1.They will burst. 2.They will shrink. 3.Nothing will happen. 4.They will expand but not burst. 5.None of the above.

25 The U-shaped tube in the figure below is divided by a membrane that is impermeable to starch but permeable to water. Which of the following will occur? 1.Water will move from the right to the left. 2. Water will move from the left to the right. 3.Starch will move from the right to the left. 4.Starch will move from the left to the right. 5.Nothing will happen. The membrane blocks the passage of all the molecules.

26 Where do new cells come from? A. From the lymph glands. B. From preexisting cells C. From food molecules in the digestive tract. D. From the blood

27 Which process requires a cell to use energy to move materials across its membrane when a concentration difference does not exist? A. active transport B. diffusion C. mitosis D. osmosis

28 Why must homeostasis be maintained in a cell? A. Water will enter the cell if homeostasis is not maintained. B. Salt will leave the cell if homeostasis is not maintained. C. Wastes, water and nutrients must stay in the correct balance. D. The cell membrane will lose the lipid bi-layer without homeostasis.
