| If we double the surface area of a plasma membrane, what happens to the volume of the cell? | increases 8 times |
| List the components of the Cell Theory. | All life is cellular; all life functions as a result of their cells; all cells come from pre-existing cells |
| Which proteins within the plasma membrane transport material into or out of a cell? | integral proteins |
| Integral proteins are also called _________. | transport proteins; carrier proteins; channel proteins |
| The phospholipid molecule is a head that is _____________ and a tail that is ____________. | hydrophilic; hydrophobic |
| Having Hydrophilic properties means a molecule _________ dissolve in water. | will |
| Having Hydrophobic properties means a molecule __________ dissovle in water. | will not |
| A lipid bilayer will form because of ___________ producing clusters of their fatty acid tails. | hydrophobic reactions |
| The lipid bilayer produces a hydrophobic barrier between 2 environments containing_______. | water based |
| The latest model of the plasma membrane proposed by Singer and Nicholson is called the ______________. | fluid mosaic model |
| The fluid mosaic model is best described as a ________________________________________. | phospholipid bilayer with embedded proteins |
| Prokayotes lack an organized ______________. | nucleus |
| A long protein fiber containing organelle used in cell movement. | flagella |
| A dense region of RNA within the nucleus responsible for ribosome production. | nucleolus |
| Referred to as rough or smooth depending upon the presence of attached ribosomes. | endoplasmic recticulum |
| The primary organelle of protein production. | ribosomes or rough ER |
| Lipids and carbohydrates are produced here. | smooth endoplasmic recticulum |
| Products of organelles are packaged here for secretion out of the cell. | Golgi apparatus |
| Organelles containing hydrolytic enzymes used in intracellular digestion | lysosome |
| What portions of the Endomembrane System would be involved in protein production and secretion? | rough ER and Golgi apparatus |
| Fluid filled sacs used in liquid storage of compounds within a plant cell and taking up much of the cell's volume. | central vacuole |
| List 3 cell structures found in plant cells but not animal cells. | cell wall, central vacuoles, plastids |
| The primary organelles of ATP production. | mitochondria and chloroplasts |
| The organelles that breakdown glucose and generate ATP during cellular respiration. | mitochondria |
| Mitochondria release the energy stored in the chemical bonds of ________________. | glucose |
| In plant cells, the organelles of photosynthesis. | chloroplasts |
| In animal cells, the organelles of chromosomes movement during cell reproduction. | centrioles |
| The long filament that moves a cell by whipping back and forth. | flagella |
| The short hairlike structures that move fluid around the cell. | cilia |
| What materials are found in a plant cell wall? | cellulose, lignin, pectin |
| Cell to Cell junctions in animal cells that allow communication between cells. | gap junctions |
| Electron microscope has more magnification capabilities but how is the compound light microscope more advantageous? | lets you see living cells |
| the 2 major structural differences between prokaryotes and eukaryotes | prokaryotes lack a nuclear membrane and membrane bound organelles |
| what is the major limitation in a cell's size? | the surface area of the cell's plasma membrane verses the volume of the cytoplasm |
| what 2 domains are bacteria found in? | Archaea and Bacteria |
| centrioles are not found in ____________ | plant cells |
| a cell with extensive network of rough ER and ribosomes would likely be involved in the production of | proteins |
| proteins remaining within the cytoplasm will be formed by what type of ribosome? | free floating |
| proteins that will be exported from a cell are produced at which structure? | rough ER |

| 2 most common types of plastids | chloroplast, leucoplasts |
| what is responsible for movement of vesicles and organelles within the cell? | microtubules and motor proteins |
| what structures in plant and animal cells allow materials to pass from cell to cell | plasmodesmata in plants and gap junctions in animal cells |
| organelle converting light energy to ATP energy | chloroplast |
| organelle converting food energy to ATP energy | mitochondria |
| location of ribosomes producing proteins | rough ER |
