FRESHMAN CELL TEST
Cells
| Question/Deffinition | Answer |
|---|---|
| Everything is allowed in and out | Permeable |
| Nothing is allwed in or out | Impermeable |
| Certain things are allowed in and out | Selectively Permeable |
| Movement of molecules from higher to lower concentration; does not require energy | Passive transport |
| Movement of any molecule from higher to lower concentration | Diffusion |
| Movement of water from higher to lower concentraion | osmosis |
| The movement of molecules from lower to higher concentraions; requires energy | Active Transport |
| Example of Diffusion | Smells |
| A process by which large particles enter a cell | Endocytosis |
| Process by which large particles exit a cell | Exocytosis |
| Process by which a white blood cell takes over a pathogen | Phagocytosis |
| Pressure against the cell membrane from within the cell | Turgor pressure |
| Increase in pressure for an animal cell; cell bursts | Cytolysis |
| Increase in pressure for a plant cell; stiff, firm | Turgid |
| Decrease in pressure for an animal cell; soft and limp | Flaccid |
| Decrease in pressure for a plant cell; wilts | Plasmolysis |
| Equal #s of molecules on both sides of the membrane; pressure remains contrant | Equilibrium |
| Balance between a cell and its environment; pressure remains constant | Homeostasis |
| MORE water molecules than another environment (less solutes) | Hypotonic |
| LESS water molecules than another environment (more solutes) | Hypertonic |
| Equal amounts of water molecules | Isotonic |
| Cells store energy in bonds of ___ | ATP |
| ATP stands for___ | Adenosine TRIphosphate |
| ATP is the energy currency of the cell within the ___ | Mitochondria |
| ADP stands for___ | Adenosine DIphosphate |
| How is ATP made? | Bonding a phosphate group to ADP stores energy and makes ATP |
| Breaking down ATP to ADP and a phosphate group ___ energy | releases |
| This cell part changes energy from one form to another | Mitochondria |
| Chemical equation for aerobic respiration: | C6H12 + 6O2 ----> 6CO2 + 6H2O + energy |
| Traps energy from sunlight to convert it into chemical energy (glucose) during the process of photosynthesis | Chloroplasts |
| Chemical equation for photosynthesis (takes placce in chloroplast) | 6 C O2 + 6 H2 O ----> C6 H12 O6 + 6 O2 |
| The equation for aerobic is ____ the equation for photosynthesis | Opposite |
| I am a green organelle that transforms light energy to chemical energy to be used as food | Chloroplats |
| I produce proteins in a cell | Ribosomes |
| I store the RNA that will make the ribosomes | Nucleus |
| I am the liquid that fills up the cell | Cytoplasm |
| I am an opening in the nuclear membrane and allow molecules to pass through | Nuclear Pore |
| I am a canal or "highway" that transports molecules within the cell | ER |
| I regulate what comes into or out of the cell | Cell Membrane |
| I am the control center of the cell; I contain DNA | Nucleus |
| I contain digestive enzymes; I also break down worn or excess cell parts | Lysosomes |
| I release energy in the cell by breaking down glucose | Mitochondria |
| I become the Chromosomes when the cell is about to divide | Chromatin |
| I store water and minerals in the plant cells | Vacuole |
| I aid in cell division in animal cells; I am not found in plant cells | Centriole |
| I package molecules to be sent out to other cells | Golgi Body |
| All living thins are made up of units called______ | cells |
| Who suggested that all animals are made of cells | Schwann |
| ___ is an organism made up of only one cell | Unicellur |
| Who was the 1st person to examine cells under the microscope? | Leeuwenhoek |
| Who suggested that all plants are made up of cells? | Schleiden |
| Who proposed that all living things were composed of cells? | Hooke |
| ___ cells are true cells with a membrane-bound nucleus and membrane bound organelles | Eukaryotic |
| ___ cells are cells that do not have a membrane-bound nucleus or organelles | Prokaryotic |
| ___ describes an organism that is made of many cells | Multicelluar |
| 3 parts of cell thory are... | (1) all things are made of cells, (2) cells are the unit of all living things, (3) all cells come from existing cells |
| DO YOU KNOW.... | CELL DIAGRAM? |
