Hard
| Question | Answer |
|---|---|
| As a ____ size increases, its volume increases much more than its surface area | Cell |
| What would happen if a cells size doubled? | The cell would require 8 times more nutrients and would have 8 times more waste to excrete |
| How much would the surface area increase? | By a factor of 4 |
| What does cell division result in? | two cells that are identical to the original, parent cell |
| What is interphase? | The busiest phase of cell cycle that is divided into 3 parts |
| What happens during the first part (GI Phase)? | The cell grows and protein production is high |
| What happens in the second phase (S Phase)? | The cell copies its chromosomes |
| What happens in the G3 Phase? | Centrioles replicate, Cell prepares for division |
| Prophase? | The chromatin coils to form chromosomes, the nuclear envelope disappears, Spindle fibers form, longest phase of MiToSiS. |
| Metaphase? | |
| Anaphase? | Centromeres split, chromatids are pulled apart to opposite poles of the cell. |
| Telophase? | The nuclear envelope reappears, The cell begins the divide/split/seperate, Chromosomes are at the opposite of the poles, the cell’s cytoplasm divides in a process called CyToKiNeSiS |
| What structure is known for laying down across the cells equator of plant cells? | Cell plate |
| What is the movement of particles from an area of higher concentration to lower concentration? | Diffusion |
| What is unequal distribution of particles, called a concentration gradient a factor of? | Ossmosis |
| 90% H20, 10% Starch; The cell remains the same size & shape; more enters than leaves? | Isotonic Solution "The Same" |
| 90% H20 0% Starch; 100% H20 0% Starch; The cell will swell; More will enter than leave? | Hypotonic Solution "Below" |
| 90% H20 10% Starch in cell, 75% H20 25% Starch, More leaves than enters; The cell will shrink? | Hypertonic Solution "Above;Over" |
| What 2 things move the masses of material and require energy? | Endocytosis and exocytosis |
| What is directed by genes located on the chromosomes? | Enzyme Production |
| What forms masses of tissue called tumors that deprive normal cells of nutrients? | Cancerous Cells |
| 5th Killer in USA | Accidents |
| 4th Killer in the USA | Respiratory Disease |

| What becomes available to a cell when the molecule is broken down? | The energy of ATP |
| 6CO2 + 6H2O = C6 H12 06, + 6O2 | Photosynthesis |
| C6 H12 06, + 6O2 + 6CO2 + 6H2O | Respiration |
| Chlorophyll absorbs most wavelengths of light except what? | Green |
| Food Synthesized | Photosynthesis |
| Energy stored | Photosynthesis |
| Carbon Dioxide taken in | Photosynthesis |
| Oxygen given off | Photosynthesis |
| Sugar is produced | Photosynthesis |
| Requires light | Photosynthesis |
| Occurs when chlorophyll is present | Photosynthesis |
| Food broken down | Cellular Respiration |
| Energy released | Cellular Respiration |
| Carbon Dioxide released | Cellular Respiration |
| Oxygen taken in | Cellular Respiration |
| Co2 and H2O is produced | Cellular Respiration |
| Doesn't require light | Cellular Respiration |
| Occurs in all living cells | Cellular Respiration |
| How does diffusion limit the size of a cell? | Diffusion is slow over long distances, and larger cells can't transport throughout efficently |
| How does DNA limit the size of a cell? | One set of the cells proteins isn't enough |
| How does surface area-to-volume ratio limit the cell size? | If the cell is larger than how it should be unable to receive or dispel whatever it has |
| Causes a cell to swell? | Hypotonic Solution |
| Doesn't change the shape of the cell? | Isotonic Solution |
| Causes Osmosis? | Isotonic, Hypotonic, & Hypertonic Solution |
| Causes cell to shrink? | Hypertonic Solution |
| Transport protein that provides a tubelike opening in the plasma membrane through which particles can diffuse | Channel Protein |
| Is used during active transport but not passive transport? | Energy |
| Process by which a cell takes in material by forming a vacuole around it? | Endocytosis |
| Particle movement from an area of high concentration to an area of lower concentration? | Passive Transport |
| Process by which a cell expels waste from a vacuole? | Exocytosis |
| A form of passive transport that uses transport proteins? | Facilitated Diffusion |
| Particle movement from an area of lower concentration to an area of higher concentration? | Active Transport |
| Transport protein that changes shape when a particle binds with it? | Carrier Protein |
