Photosynthesis Flashcards
How do green plants absorb light energy?
By using the chlorophyll in their leaves. They use it to react carbon dioxide with water to make glucose, and oxygen is produced as a byproduct.
How can farmers/gardeners use knowledge of limiting factors to their advantage?
They can use things such as artificial light, temperature controls, burners that produce carbon dioxide which all allow for faster rates of photosynthesis.
what is the photosynth equation: ?
light energy
carbon dioxide + water ————–> glucose + oxygen
what three limiting factors of photosynthesis?
Light, Carbon Dioxide concentration, Temperature.
what are the three main parts of photosynthesis?
Absorbed energy is used to convert carbon dioxide from the air and water from the soil into a sugar called glucose.
Oxygen is released as a by-product.
Which part of a plant absorbs light energy?
Light energy gets absorbed by chlorophyll.
Where does photosynthesis occur?
In the leaves of a green plant.
Why do plants need to be kept under certain conditions?
Because without a specific element required for Photosynthesis, the process cannot happen.
Why does a plant need to be kept at a specific temperature.
It’s enzymes begin to denature, therefore the temperature cannot be too high or too low, as both of these can cause the enzyme to denature.
How is glucose stored in a plant?
It is stored as starch and in fats and oils.
What is glucose used to produce in a plant?
Cellulose - which strengthens the cell wall
Proteins - enzymes and chlorophyll
What is nitrate used for?
Nitrate is another essential mineral needed to make proteins, it gets absorbed from the soil………………….
