Study for Bio I Test 2
| Question | Answer |
|---|---|
| All living things are composed of these. | Cells |
| Two Classifications of cells | Eukaryotes and Prokaryotes |
| Two sub-classifications of Prokaryotes | Bacteria and Archea |
| All cells contain | Plasma Membrane, nucleus and ribosomes |
| Only animal cells have | lysosomes |
| Only plant cells have | chloroplasts,cell walls and central vacuoles |
| These are selectively permeable | membranes |
| This type of transport does not require energy | passive |
| This type of transport does require energy | active |
| Active transport uses this type of energy | ATP |
| Process in which molecules move down concentration gradient | diffusion |
| diffusion of water | osmosis |
| When larger molecules move through embedded transport proteins | Facilitated Diffusion |
| Process that imports materials to cell | Endocytosis |
| Process that exports materials out of cell | Exocytosis |
| Materials that need to be moved are carried in a structure called | vesicle |
| This is stored in chromosomes | DNA |
| Directs activity of the cell | Nucleus |
| The nuclear membrane contains these to let materials through | pores |
| DNA molecules wrapped around proteins | chromatin |
| chromatin folds to form a | chromosome |
| Produces ribosomal RNA | Nucleolus |
| DNA contains instructions for the construction of | proteins |
| Involved in nearly all cell functions | proteins |
| Sight of protein production | Ribosomes |
| Two types of Endoplasmic Reticulum (ER) | Smooth and Rough |
| Golgi Apparatus is responsible for | packaging |
| The process in which DNA is broken to make mRNA | Transcription |
| Process that occurs in cytoplasm; advances to golgi to be modified | Translation |
| Some are embedded in rough ER, while others float freely in cytoplasm | Ribosomes |
| Contains enzymes that produce lipids | Smooth ER |
| Contains ribosomes that produce proteins | Rough ER |
| Finishes, sorts and ships cell products | Golgi Apparatus |
| Shipping method for exocytosis | Secretory |
| Proteins can become a component of | Plasma Membrane |
| Provides energy for all cells | Organelles |
| In all plant cells and some algae | chloroplasts |
| Powerhouse of the cell | Mitochondria |
| Ooccurs in chloropolasts | Photosynthesis |
| Intracellular Sacs that store food and nutrients | Vacuoles |
| Single hair-like that propels sperm cells | flagella |
| Small hair-like structures that move materials across the cell membrane | cilia |
| Structure in plants and fungi that is made of cellulose | Cell wall |
| Network of protein fibers that provide mechanical support, anchorage and reinforcement | Cytoskeleton |
| Defined as the capacity to do work | Energy |
| Energy due to it's location or structure | Potential |
| Energy of motion | Kinetic |
| Energy cannot be | created or destroyed |
| Energy can be | Converted |
| Biproduct of energy conversion | Heat |
| Type of energy used by plants | Solar Energy |
| Convert suns energy into chemical energy | Producers |
| Process in which oxygen is used to harvest energy stored in sugar | Cellular Respiration |
| Cellular Respiration occurs in | Mitochondria |
| Cellular Respiration occurs as the type of respiration | aerobic |
| `This builds up in muscles | Lactic Acid |
| Name for egg and sperm cells | Gametes |
| Name for testes and ovaries | gonads |
| This is a segment of DNA | gene |
| In preparation for division of chromosomes | Interphase |
| During interphase the cell | grows, normal functions, duplicates chromosomes |
| Phase where cell undergoes active division | Mitotic Phase |
| 22 pairs of chromosomes are called | autosomes |
| chromosomes organized into homologous pairs | karyotypes |
| Two rounds of cell division, resulting in four haploid cells | meiosis |
