🗑
|
||||
| Energy from the sun enters living systems through ______ such as plants and certain prokaryotes | autotrophs
🗑
|
||||
| Animals get energy from food through the process of | cellular respiration

🗑
|
||||
| Organisms extract energy stored in glucose through the process of cellular | respiration
🗑
|
||||
| ______ is the organic molecule that is the main energy source for cell processes and is made with the energy released from the breakdown of glucose | ATP
🗑
|
||||

🗑
|
||||
| The abundance of oxygen in Earth's atmosphere is a result of the process of | photosynthesis
🗑
|
||||
| Why is chlorophyll green | it reflects green
🗑
|
||||
| The cause of photosynthesis | photosynthesis makes oxygen
🗑
|
||||
| Which of the following enables plants to light | hydrogen ion pumps
🗑
|
||||
| The source of oxygen during production | water
🗑
|
||||
| Products of dark reactions during photosynthesis | ATP AND NADPH
🗑
|
||||
| During the final stage of photosynthesis, sugars are made from | carbon dioxide

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.
