Chapter 8 - Photosynthesis Flashcards
What type of reaction is Photosynthesis?
Photosynthesis is an endothermic reaction.
During photosynthesis what is transferred from the environment by light?
During photosynthesis energy is transferred from the environment to the chloroplast by light
What is photosynthesis used for?
Photosynthesis is used to convert carbon dioxide and water into sugar (glucose) and Oxygen which is released as a by-product.
What is the equation formula for Photosynthesis?
light
carbon dioxide + water ——> glucose + oxygen
How are leaves will adapted to allow the maximum amount of photosynthesis to take place?
Most leaves are broad, giving them a big surface area for light to fall on
Most leves are thin so diffusion distances for the gases are short.
They have air spaces that allow carbon dioxide to get to the cells, and oxygen to leave by diffusion.
What four things affects the rate of Photosynthesis?
The rate of photosynthesis may be effected by light intensity, temperature, level of carbon dioxide, and the amount if chlorophyll.
Investigate the experiment for light intensity and rate of photosynthesis.
In this investigation you should see bubbles, the amount of bubbles determines on the distance of the lamp from the beaker. The further away the beaker, the less photosynthesis (less bubbles) and the closer the lamp from the beaker, the more photosynthesis (more bubbles).
