Can you list the 3 things that are transported around a plant? | Water, Minerals, Chlorophyll.
🗑
|
||||
What direction does water travel in a plant? | Up.
🗑
|
||||
Can you give the definition for transpiration? | Transpiration is the loss of water vapour from the surface of a plant.
🗑
|
||||
Why do plants need to transpire? | To cool down and to draw water into the roots.
🗑
|
||||
Can you name the tissue that transports water and nutrients from the roots to the leaves? | Xylem.
🗑
|
||||
Can you name the tissue that transports food from the leaves to the rest of the plant? | Phloem.
🗑
|
||||
How does water get removed from a plant? | Evaporation from the leaves after transpiration.
🗑
|
||||
What cells in the leaf allow gas exchange? | Stomata.
🗑
|
||||
What is the definition of photosynthesis? | The converting of light, water and carbon dioxide into glucose and oxygen.
🗑
|
||||
Why is photosynthesis so important for us and other animals? | It takes in carbon dioxide and releases oxygen.
🗑
|
||||
What part of the plant does photosynthesis take place in? | The leaves.
🗑
|
||||
What is the chemical in leaves that allows photosynthesis take place? | Chlorophyll.
🗑
|
||||
What substances do plants need for photosynthesis? | Chlorophyll, Carbon dioxide, Water, Light,
🗑
|
||||
What are the tiny holes on the leaf that allow gas exchange called? | Stomata.
🗑
|
||||
What gases do the stomata allow in and out? | Carbon dioxide, Oxygen and Water vapour.
🗑
|
||||
How does water get into the leaf? | Through the plant roots and by gaseous exchange.
🗑
|
||||
What do plants make in photosynthesis? | Glucose and Oxygen.
🗑
|
||||
Can you write a balanced equation for photosynthesis? | 6CO2 + 6H2O ------> C6H12O6 + 6O2
🗑
|
||||
How do plants respond to their surroundings? | Tropism.
🗑
|
||||
What is a tropism? | A tropism is a plants growth response to a stimulus.
🗑
|
||||
What is phototropism? | Phototropism is a plants growth response to light, the plant will grow toward the light.
🗑
|
||||
What is Geotropism? | Geotropism is a plants growth response to gravity, the pant shoot will grow away from gravity and the roots toward it.

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.
