Cell Organelles and Transport Question #1 (1 point) Vesicles that digest worn-out organelles or food particles are called ____. lysosomes centrioles plasma membranes ribosomes Question #2 (1 point) Which part of a plant cell contains chlorophyll? The nucleus The cytoplasm The chloroplasts The cell membrane Question #3 (1 point) What do we call a group of different tissues are organized into larger structure? An organ Organ system Bioaccumulation A cell Question #4 (1 point) Which two structures do plant cells have that animal cells do not have? chloroplasts and a cell wall cell membrane and a nucleus centrioles and chloroplasts chromosomes and chlorophyll Question #5 (1 point) What is the function of a nerve cell? to store fat to contract and relax muscles to receive and deliver messages to form a protective layer for your body Question #6 (1 point) The animal cells below were placed in a hypotonic solution. What happened to the damaged cell? The cell was damaged by bacteria. Osmosis caused the cell to shrivel. Osmosis was prevented in the cell. Osmotic pressure caused the cell to rupture. Question #7 (1 point) In an isotonic solution there would be bursting of the cell shrinking of the cell net movement of water into the cell net movement of water out of the cell Question #8 (1 point) The life process ‘Growth’ depends upon cells: Filling with water and swelling Getting bigger and bigger None of these Getting bigger and dividing Question #9 (1 point) What object did Robert Hooke first observe cells in? a leaf a bacterium a cork a muscle Question #10 (1 point) Which of the following is NOT an organ? skin the heart bones blood tissue Question #11 (1 point) The sodium-potassium pump (which carries sodium out of a cell and potassium into a cell) is an example of: facilitated diffusion active transport osmosis simple diffusion Question #12 (1 point) What type of instrument is used to look at cells? binoculars glasses telescope microscopes Question #13 (1 point) What is the function of a selectively permeable membrane? prevents transport proteins from harming cell blocks all water from entering cell controls what enters and leaves cell provides alternative to phospholipid bilayer Question #14 (1 point) The statement that all cells come from cells that already exist is part of __________. the reproductive theory the cell theory Hooke's theory the fossil record Question #15 (1 point) What is a microscope? The machine used to take X-rays A measuring tool Something used to study small objects A tiny piece of equipment Question #16 (1 point) Which part of the cell controls the activities inside the cell? Cell wall Nucleus Cell membrane Cytoplasm Question #17 (1 point) What is the smallest unit of life in all living things called? a molecule an atom a cell bacteria Question #18 (1 point) Why does misting fruits and vegetables with water help them look fresh? Plants do not have a rigid cell wall. Vacuoles fill with water due to osmosis. Plant cells in a hypotonic solution lose water. Water cannot move through the cell membrane. Question #19 (1 point) Which of the following is NOT true of exocytosis? does not require energy input results in hormone secretion occurs at the plasma membrane allows waste matter to be expelled Question #20 (1 point) What determines which traits an organism will have? the mitochondrion the nucleus DNA cytoplasm Question #21 (1 point) Why do plant cells behave differently to animal cells when placed in a hypotonic solution? Plant cells have cell walls Plant cells are permeable to water Plant cells contain central vacuoles Plant cells do not carry out active transport Question #22 (1 point) Cellulose is a strong substance found in all plant cells. Which part of a plant cell contains cellulose? The vacuoles The cell wall The cell membrane The chloroplasts Question #23 (1 point) Which of the following is an organ? blood tissue stomach nerve tissue muscular system Question #24 (1 point) Which of these things do both plant and animal cells have? Cell wall Central vacuole Cytoplasm Chloroplasts Question #25 (1 point) Which of the following are the smallest organisms on Earth? shrimp algae mold bacteria Question #26 (1 point) Put the level of organization in order from smallest to largest. cells, tissues, organs, and organ systems cells, organs, tissues, and organ systems organ system, organs, tissues, and cells organs, tissues, cells, and organ system Question #27 (1 point) What were the tiny compartments that Robert Hooke saw in pieces of cork? Cubes Boxes Particles Cells Question #28 (1 point) Which of these is similar in function to a vacuole? a bakery manager an electric circuit a wall a closet Question #29 (1 point) What describes transport proteins moving molecules across the plasma membrane? osmosis diffusion facilitated diffusion dynamic equilibrium Question #30 (1 point) Plants, algae, and many bacteria make their own food through the process of __________. cellular respiration photosynthesis digestion metabolism Question #31 (1 point) What does the lens on a microscope do? Change the amount of light passing through the microscope Hold the slide Move the stage Focus the image Question #32 (1 point) Groups of similar cells that all do the same sort of work are called __________. cell systems organ systems tissues organs Question #33 (1 point) Where does cellular respiration occur? in the vacuole in the chloroplasts in the mitochondrion in the lungs Question #34 (1 point) Which of the following is NOT a function of the Golgi apparatus? produces proteins organizes where proteins are sent modifies proteins packages proteins into vesicles Question #35 (1 point) In which cell structure are ribosomes produced? nucleolus microtubules golgi apparatus plasma membrane Question #36 (1 point) Where is the hereditary material located in the cell? the mitochondrion the nucleus the vacuole the cell membrane Question #37 (1 point) The semifluid environment inside the plasma membrane is called ____. mitochondria microtubules endoplastic reticulum cytoplasm Question #38 (1 point) Which types of cell have a definite shape? Neither animal or plant cells Plant cells Animal cells Both animal and plant cells Question #39 (1 point) What part of the cell helps control what enters and leaves the cell? cell membrane nucleus cytoplasm mitochondrion Submit Logout
