1The organelle that digests food particles, wastes, cell parts, and foreign invaders VacuoleLysosomeCytoplasmRibosome
2In plant cells, this stiff wall surrounds the cell membrane, giving the cell a rigid, boxlike shape. Cell WallCell MembraneVacuoleNuclear Envelope
3Thin, flexible barrier around a cell, it regulates what enters and leaves the cell Cell WallGolgi ApparatusCell MembraneNucleus
4Vacuole Ribosome Cell Membrane Nucleus 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)VacuoleRibosomeCell MembraneNucleus
5Cells that do not have a distinct nucleus are called: ProkaryoticEukaryoticMulticellularAnimal
6The jellylike fluid that contains nutrients in a cell is the: CytoplasmE.R.Golgi ApparatusLysosome
7Small organelles that are responsible for protein synthesis are the: NucleusRibosomesCytoplasmCell Membrane
8The ‘powerhouse’ of the cell that generates the cell’s energy ChloroplastE.R.Golgi ApparatusMitochondria
9The organelle found in both animal and plant cells that is clear but contains dissolved nutrients is the:CentrioleChloroplastVacuoleCell Membrane
10Cells that have internal membranes surrounding specialized organelles are: Bacteria CellsEukaryoticProkaryoticUnicellular
11Which of the following statements is false All living things are made of cells.Animal cells have a cell membrane and a cell wall.Cells come from other cells.Lysosomes are found only in animal cells.
12To enter or leave a cell, substances must pass through A microtubuleGolgi apparatusRibosomeCell Membrane
13Golgi apparatus Ribosome Mitochondria Nucleus lysosome 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?Golgi apparatusRibosomeMitochondriaNucleuslysosome
14What cell structure makes it possible for the internal environment of a cell to differ from the external environment?Cell wallCell membraneE.R.cytoplasm
15Which of the following are all present in animal cells mitochondria, cell membrane, cell wall, cytoplasmchloroplasts, cytoplasm, vacuole, nucleusnucleus, cell membrane, mitochondria, cytoplasmvacuole, cell membrane, nucleus, mitochondria
16Centrioles are present in _____. Animal cells onlyPlant cells onlyIn both plant and animal cellsIn neither plant nor animal cells
17The 'Scavengers' or 'Digestive bags' of a cell are ____. ChromosomesCentrosomesLysosomesRibosomes
18The network of endoplasmic reticulum is present in the ____. NucleusChromosomeCytoplasmGolgi apparatus
19Centrioles are associated with ____________. DigestionReproductionRespirationCell division
20Bacterial cells are prokaryotic; in comparison to a typical eukaryotic cell they would be smaller.have a smaller nucleus.lack a plasma membrane.have a greater variety of organelles.

23Discovered that plants are made of cells Theodor SchwannProkaryotic cellscell theoryMatthias Schleidan
24They will expand but not burst. None of the above. 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?They will burst.They will shrink.Nothing will happen.They will expand but not burst.None of the above.
25Water will move from the right to the left. 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?Water will move from the right to the left.Water will move from the left to the right.Starch will move from the right to the left.Starch will move from the left to the right.Nothing will happen. The membrane blocks the passage of all the molecules.
26Where do new cells come from? A. From the lymph glands.B. From preexisting cellsC. From food molecules in the digestive tract.D. From the blood
27A. active transport B. diffusion C. mitosis D. osmosis Which process requires a cell to use energy to move materials across its membrane when a concentration difference does not exist?A. active transportB. diffusionC. mitosisD. osmosis
28Why 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.
