I'm Lichen Bio Char of Life Unit
| Question | Answer |
|---|---|
| what elements are found in all organic molecules | C and H |
| name some inorganic compounds found in cells | water, oxygen, carbon dioxide |
| what elements are found in living things | CHON |
| what are the two parts of the cell theory | Cells are the basic unit of structure and function of living things, and all cells come from preexisting cells. |
| what is the function of enzymes | speed up the rate of chemical reactions |
| what type of organic compound is an enzyme | protein |
| what organelles are the sites of cellular respiration | mitochondria |
| what is the main result of aerobic respiration | ATP |
| what is the function of ribosomes | protein synthesis |
| name 2 cell organelles that plant cells have and animal cells don't | cell wall and chloroplast |
| used to transplant cell nuclei | microdissection instruments |
| organelle that controls the cell and contains DNA | nucleus |
| function of vacuoles in plants | store wastes |
| function of contractile vacuoles in protists | maintain water balance by pumping out excess water |
| process that moves molecules from a high concentration to a low concentration | diffusion |
| function of chloroplasts | photosynthesis |
| chemical make up of plasma membrane | double lipid layer, with proteins embedded |
| unicellular organisms like the amoeba, euglena and paramecia | Protists |
| function of cytoplasm | holds organelles, transport inside cell (streaming) and site of some chemical reactions |
| function of plasma membrane | boundary for cell, cell signaling, controls what goes in and out of cell |
| term for substance an enzyme works on | substrate |
| effect of slight increase in temp on rate of enzyme action | increase, due to molecules moving faster |
| effect of large increase in temp on rate of enzyme action | decreases rate, due to changing shape of enzyme active site, so it can no longer fit with substrate |
| how do hormones attach to cells | receptor molecules in cell membrane |
| tool to obtain detailed info about internal structure of cell organelles | electron microscope |
| in a reaction diagram, how do you identify the enzyme? | the shape that stays the same through the entire reaction |
| indicator for starch | Lugol's iodine |
| pH of 7 | neutral |
| pH of 4 | acidic |
| pH of 9 | basic |
| indicator for glucose | Benedict's solution |
| shape of plant cells | rectangular |
| use of stains such as iodine | to make cell organelles more visible, such as the nucleus |
| how to calculate the total magnification of a microscope | multiply the eyepiece X the objective |
| 1 mm = ? micrometers | 1000 |
| proper order of steps for using a light microscope | low-power, coarse adjustment, fine adjustment, medium power, fine adj, high power, fine adj |
| why do you start with low power | field of view is larger with low power, so easier to find what you are looking for |
| what type of compounds are organisms composed of | both organic and inorganic |
| why are enzymes necessary for survival | to speed up chem reactions, otherwise they would occur too slowly, organisms would die. |
| if an enzyme digests proteins, will it digest starch | no, enzymes are specific |
| if an organism carries out aerobic respiration, it must have adaptations for _____ _______ | gas exchange of oxygen and carbon dioxide |
| appearance of mitochondria | bean shaped with folded membranes inside |
| if starch is digested, what is the result | simple sugars |
| if proteins are digested, what is the result | amino acids |
| 4 differences between plant and animals cells | plant cells have large vacuoles, are rectangular, have chloroplasts and cell walls |
| know how to read enzyme graphs | check in notes and on worksheets |
| be able to label a cell diagram | use notes and worksheets |
| describe what molecules the cell membrane is made of and what they look like | lipids - 2 layers of balloons with 2 strings, and proteins - big blobs like icebergs |
| allows amount of light to be adjusted in a microscope | diaphragm |
| 2 substances used as stains for microscope work | methylene blue and Lugol's iodine |
| 3 exceptions to the cell theory | viruses, first cell, mitochondria and chloroplasts have their own DNA |
| a substance that turns color in the presence of a certain molecule | indicator |
| levels of organization from simplest to most complex | cells, tissues, organs, organ systems, organism |
| what factor was most important in the development of the cell theory | invention and improvement of microscope |
| how is the image seen through a scope different from reality | upside down and backwards |
| how do you center an off-center specimen | move the slide in the opposite direction from what it appears to need |
| indicator for protein | Biuret turns pink/purple |
| indicator for lipids | translucent spot on brown paper |
| building blocks of lipids | fatty acids and glycerol |
| molecules that can easily pass through the cell membrane | small ones, such as water, oxygen, carbon dioxide, amino acids, and glucose |
| movement of molecules from low concentrations to high concentrations | active transport |
| what is needed for contractile vacuole in protists to function | ATP |
| function of the endoplasmic reticulum | canals through the cytoplasm, carry substances from ribosomes to golgi apparatus |
| function of golgi apparatus | packages proteins |
| pigment found in chloroplasts | chlorophyll |
| word equation for respiration | glucose plus oxygen plus mitochondrial enzymes produces carbond dioxide, water and energy |
| usable form of energy for cell metabolism | ATP |
