Cell Processes
and Energy
| Question | Answer |
|---|---|
| photosynthesis | |
| autotroph | An organism that is able to capture energy from sunlight or chemicals and use it to produce its own food. |
| heterotroph | An organism that cannot make its own food and gets food by consuming other living things. |
| chlorophyll | A green photosynthetic pigment found in the chloroplasts of plants, algae, and some bacteria. |
| cellular respiration | The process in which oxygen and glucose undergo a complex series of chemical reactions inside cells, releasing energy. |
| fermentation | The process by which cells release energy by breaking down food molecules without using oxygen. |
| cell cycle | The series of events in which a cell grows, prepared for division, and divides to form two daughter cells. |
| interphase | The first stage of the cell cycle that takes place before cell division occur, during which a cell grows grows and makes a copy of its DNA. |
| replication | |
| chromosome | A threadlike structure within a cell's nucleus that contains DNA that is passed from one generation to the next. |
| mitosis | The second stage of the cell cycle during which the cell's nucleus divides into two new nuclei and one set of DNA is distributed into each daughter cell |
| cytokinesis | The final stage of the cell cycle, in which the cell's cytoplasm divides, distributing the organelles into each of the two new daughter cells. |
