Hosted By Ms. Flanagan Discovering Cells Looking Inside Cells Chemical Compounds in Cells 100 100 100 100 200 200 200 200 300 300 300 300 400 400 400 400 500 500 500 500 Cell in its Environment magnification = bigger, resolution = clarity What is the difference between resolution and magnification? Row 1, Col 1 Cell wall only in plant, membrane in all How are the cell membrane and cell wall different? 1,2 Speed up chemical reactions What do enzymes do that is important for our bodies? 1,3 osmosis Which term refers to the diffusion of water molecules through a selectively permeable membrane? 1,4 function Cells are the basic unit of structure and ______________ in living things. 2,1 ribosomes Which organelle produces proteins? 2,2 starches Sugar molecules can combine with one another to form large molecules called _____. 2,3 High concentration, Low concentration Diffusion is the movement of molecules from areas of _______________ to __________________. 2,4 Other cells According to the cell theory, where do all cells come from? 3,1 Mitochondria = turns food to energy, Chloroplast = turns sunlight energy to food energy How are mitochondria and chloroplasts different? 3,2 Make up cell membrane, store energy What is the function of lipids? 3,3 Active Transport The movement of materials across the cell membrane when energy is required. 3,4 200x If a compound microscope has a 10x lens in its eyepiece and a 20x lens in its nosepiece, its total magnification is _____. 4,1 Repackage and send out proteins to parts of the cell What is the function of the golgi apparatus? 4,2 Foods with a lot of lipids. (more energy) What types of foods should a bear eat before hibernation? Why? 4,3 Molecules will be moving faster Why would raising the temperature make diffusion happen faster? 4,4 Robert Hooke Who first observed cells? 5,1 Tissue, organism Cells _____ Organ Organ system _______ 5,2 Nucleic acids; DNA ______ are the chemical compounds that contain the instructions that cells need to carry out all the functions of life. 5,3 It chooses what can enter/exit the cell The cell membrane is selectively permeable. What does that mean? 5,4
