Which structure is much larger in a PLANT cell than an animal cell? a. cell membrane b. mitochondria c. vacuole d. nucleus Groups of cells make up ___, which are organized to make up ___. a. tissues, organs b. tissues, organisms c. organs, systems d. organs, tissues Which is NOT commonly found in the cell membrane? a. carbohydrates b. lipids c. nucleic acids d. proteins The function of the cell’s ribosomes is to make: a. the nucleolus b. DNA c. the ER d. proteins What organelle is known as the “fence” or “screen” because it is selectively permeable? a. cell membrane b. cell wall c. nucleus d. nucleolus Cell components which have a specific function in the cell and whose name means “little organ” are: a. molecules b. water molecules c. lysosomes d. organelles Why is the lysosome named the “suicide bag”? a. it secretes cytoplasm and if it stopped, the cell would die. b. it contains digestive enzymes that, if spilled, would kill the cell. c. it routinely dissolves itself. d. it is black in color, like the Grim Reaper The processing, packaging and shipping area of the cell is its “post office” or: a. Golgi Body b. ER c. nucleus d. cell membrane If a cell could not produce enough energy even though plenty of food was available, which organelle might be defective? a. mitochondria b. Golgi Body c. ER d. nucleus The “highway of the cell” which moves things throughout the cell is the: a. mitochondria b. leucoplast c. ER d. centrioles Plant cells have a special organelle for storing food (starch). It is the: a. lysosome b. leucoplast c. chloroplast d. centrioles The passage of large molecules OUT of a cell using some of the cell’s energy is called: a. endocytosis b. exocytosis c. osmosis d. diffusion The movement of substances from an area of LOWER concentration to an area of HIGHER concentration which takes a cell’s energy is called: a. plasmolysis b. passive transport c. phagocytosis d. active transport The process by which molecules spread from an area of higher concentration to an area of lower concentration is known as: a. plasmolysis b. cytolysis c. diffusion d. osmosis If an Elodea cell (or any plant cell) appears square in shape, it is the result of a cell structure used for support and protection called the: a. chloroplast b. vacuole c. cell membrane d. cell wall Which of the following would most likely contain chlorophyll in chloroplasts? a. giraffe b. oak tree c. bacteria d. water How many layers of lipids form the cell membrane? a. 2 b. 3 c. 4 d. 5 Pinocytosis and Phagocytosis are examples of which process? a. plasmolysis b. cytolysis c. exocytosis d. endocytosis Biological balance between an organism (or a cell) and its environment is called: a. hypertonic b. hypotonic c. diffusion d. homeostasis When a cube of sugar is placed in a cup of water, the molecules spread through the cup from an area of higher concentration to an area of lower concentration by which process? a. diffusion b. osmosis c. facilitated diffusion d. active transport The cell organelle used during endocytosis and / or exocytosis is the: a. cell membrane b. nucleus c. mitochondria d. ER What kind of solution surrounds a slug if you poured salt on it to kill it? (Don’t do this unkind thing to animals, of course!!) a. hypertonic b. hypotonic c. isotonic d. equilibrium What is the major difference between diffusion and osmosis? a. osmosis is an example of active transport; diffusion is passive. b. osmosis is movement of water molecules, diffusion is movement of ANY molecule. c. diffusion requires a membrane; osmosis does not. d. osmosis is movement of ions only; diffusion moves water Water in a solution is always the: a. solute b. dilution factor c. solvent d. carbohydrate A biologist would expect any newly discovered organism to be composed of cells because of the: a. adaptation theory b. water of cells theory c. cell theory d. Virchow contribution The part of the cell that makes the ribosomes is the: a. mitochondria b. ER c. nucleus d. nucleolus Which type of cell would you expect to have more mitochondria than the rest? a. muscle cells b. skin cells c. plant cells d. hair cells Which cellular organelle is essential for photosynthesis to occur? a. cell wall b. chloroplast c. centrioles d. cell membrane Which organelle would NOT be found in a plant cell? a. cell wall b. chloroplast c. centrioles d. cell membrane Which level of multicellular organization would a HEART be? a. tissue b. organ c. organ system d. organism Which level of multicellular organization would a BONE be? a. tissue b. organ c. organ system d. organism Which level of multicellular organization would a PLANT be? a. tissue b. organ c. organ system d. organism Which cellular organelle contains DNA, and therefore, controls all cell functions? a. nucleus b. mitochondria c. cell membrane d. centriole Eukaryotes have ___, while prokaryotes do not. a. mitochondria b. hearts c. a nucleus d. DNA Which of the following would NOT contain EUKARYOTIC cells? a. mushroom b. human c. tree d. bacteria
