|---|---|---|---|---|---|
| Autotroph | an organism that CAN make its own food (ex. plant)
🗑
|
||||
| heterothroph | an organism that CANNOT make its own food (ex. animal)
🗑
|
||||
| chlorophyll | the main photosyntheticic pigment (green) that captures light energy and uses it to power stage 2 of photosynthesis
🗑
|
||||
| stomata | small openings on underside of a leaf that lets CO2 enter and O2 exit
🗑
|
||||
| chloroplast | organelle in plants that contains chlorophyll
🗑
|
||||
| respiration | the process by which organisms use food and oxygen to make energy
stage 1 - cytoplasm
stage 2 - mitochondria
🗑
|
||||
| mitochondria | where stage 2 of respiration takes place. broken down pieces of glucose along with oxygen create a release of energy
🗑
|
||||
| photosynthesis equation | plants make food from sunlight
6 CO2 + 6 H2O - SUNLIGHT - C6 H12 O6 + 6 O2
🗑
|
||||
| respiration equation | C6 H12 O6 + 6 O2 -------> 6 CO2 + 6 H2O + Energy
🗑
|
||||
| Water | H2O
🗑
|
||||
| Glucose | C6 H12 O6
🗑
|
||||
| Carbon Dioxide | CO2
🗑
|
||||
| Oxygen Molecule | O2
🗑
|
||||
| What happens during photosynthesis? | Stage 1 - chlorophyll captures light energy from the sun
Stage 2 - light energy transforms water and carbon dioxide into glucose and oxygen
🗑
|
||||
| What happens during respiration? | Stage 1 - glucose is broken down into small molecules in the cytoplasm. tiny amount of energy is released
Stage 2 - broken down glusose along with oxygen enter mitichondria release energy CO2 and H2O
🗑
|
||||
| Reactants needed for photosynthesis | 6 water (h2o) and 6 carbon dioxide (co2)
🗑
|
||||
| Reactants for Respiration & Products of Photosynthesis | 1 glucose and 6 oxygen
🗑
|
||||
| Products of Respiration | 6 carbon dioxide, 6 water and Energy
🗑

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.
