|---|---|---|---|---|---|
| Autotrophs | organisms such as plants that make their own food
🗑
|
||||
| Heterotrophs | obtain energy from the food they consume (animals)
🗑
|
||||
| ATP (adenosine triphosphate) | one of the principal chemical compounds that cells use to store and release energy
🗑
|
||||
| Photosynthesis | plants use the energy of sunlight to convert water and carbon dioxide into high-energy carbohydrates and oxygen
🗑
|
||||
| Pigments | light-absorbing molecules that help plants gather energy
🗑
|
||||
| Chlorophyll | a plant's principal pigment
🗑
|
||||
| Thylakoids | saclike photosynthetic membranes contained in chloroplasts
🗑
|
||||
| Photosystems | clusters which are the light-collecting units of the chloroplast
🗑
|
||||
| Stroma | the region outside the thylakoid membranes where the Calvin Cycle takes place
🗑
|
||||
| NADP+ | NADP+ accepts and holds 2 high-energy electrons along with a hydrogen ion (H+). This converts the NADP+ into NADPH.
🗑
|
||||
| Light-dependent reactions | require light to produce oxygen gas and convert ADP and NADP+ into ATP and NADPH
🗑
|
||||
| ATP synthase | a protein in the cell membrane that spans the membrane and allows H+ ions to pass through it
🗑
|
||||
| Calvin Cycle | plants use the energy that ATP and NADPH from the light-dependent reactions to produce high-energy sugars
🗑

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.
