|---|---|---|---|---|---|
| Photosynthesis | The process by which plants and some other organisms capture the energy in sunlight and use it to make food.
🗑
|
||||
| Autotroph | An organism that makes its own food.
🗑
|
||||
| Heterotroph | An organism that cannot make its own food.
🗑
|
||||
| Pigment | A colored chemical compound that absorbs light.
🗑
|
||||
| Chlorophyll | A green pigment found in the chloroplasts of plants, algae, and some bacteria.
🗑
|
||||
| Stomata | Small openings on the underside of a leaf through which oxygen and carbon dioxide can move.
🗑
|
||||
| Respiration | The process by which cells break down simple food molecules to release the energy they contain.
🗑
|
||||
| Fermentation | The process by which cells break down molecules to release energy without using oxygen.
🗑
|
||||
| Respiration Equation | C₆H₁₂O₆ + 6 O₂ → 6 CO₂ + 6 H₂0 + ENERGY
🗑
|
||||
| Photosynthesis Equation | 6 CO₂ + 6 H₂0 → (light energy) C₆H₁₂O₆ + 6 O₂
🗑
|
||||
| What are the two types of fermentation? | Alcoholic and Lactic
🗑
|
||||
| → | Yielded by (connects raw materials to products)
🗑
|
||||
| Where does the first stage of respiration take place and what happens? | Takes place in cytoplasm of the organism's cell's. Molecules of glucose broken down into smaller molecules (oxygen not involved, small amount of energy released).
🗑
|
||||
| Where does the second stage of respiration take place and what happens? | Takes place in mitochondria. Small glucose molecules broken down into even smaller molecules (requires oxygen and a great deal of energy is released).
🗑
|
||||
| Cell Cycle | The regular sequence of growth and division that that cells undergo
🗑
|
||||
| Interphase | The stage of the cell cycle that takes place before cell division occurs.
🗑
|
||||
| Replication | The process by which a cell makes a copy of the DNA in its nucleus.
🗑
|
||||
| Mitosis | The stage of the cell cycle during which the cell's nucleus divides into two new nuclei and one copy of the DNA is distributed into each daughter cell.
🗑
|
||||
| Chromosome | A doubled rod of condensed chromatin; contains DNA that carries genetic information.
🗑
|
||||
| Cytokinesis | The final stage of the cell cycle, in which the cell's cytoplasm divides, distributing the organelles into each of the two new cells.
🗑
|
||||
| Cancer | A disease in which some body cells grow and divide uncontrollably, damaging parts of the body around them.
🗑
|
||||
| Mutation | A change in a gene or chromosome.
🗑
|
||||
| Tumor | A mass of abnormal cells that develops when cancerous cells divide and grow uncontrollably.
🗑
|
||||
| Chemotherapy | The use of drugs to treat diseases such as cancer. "Cocktail"
🗑

Review the information in the table. When you are ready to quiz yourself you can hide individual columns or the entire table. Then you can click on the empty cells to reveal the answer. Try to recall what will be displayed before clicking the empty cell.
To hide a column, click on the column name.
To hide the entire table, click on the "Hide All" button.
You may also shuffle the rows of the table by clicking on the "Shuffle" button.
Or sort by any of the columns using the down arrow next to any column heading.
If you know all the data on any row, you can temporarily remove it by tapping the trash can to the right of the row.
