carbon dioxide and water, in the presence of light
what are the products of photosynthesis
glucose and oxygen
where does photosynthesis occur
in the chloroplasts
Why are there no chloroplasts in roots
roots are underground and not exposed to sunlight
Would you expect a plant to produce more oxygen on a cloudy day or a sunny day?
Sunny. Light is needed for photosynthesis
How does a plant obtain carbon dioxide
It comes in through the stomata on the underside of the leaf
what is glucose
a simple sugar
How does a plant obtain water
through the roots
What is the pigment in chloroplasts called
Why is light not considered a reactant
It is not used or rearranged in the reaction.
What kind of organisms can do photosynthesis?
Only organisms like plants, some bacteria and some protists (algae)
Why are plants called producers
They are the only organisms that can make their own food
What would happen to the animals if the sun did not shine
animals would die because they are reliant on the sun to provide energy to plants to make food.
Who does cellular respiration
plants and animals
What is the purpose of respiration
to make energy for the cell
What part of a cell does respiration
Why would you expect to find more mitochondria in the heart than in the skin
The heart is a muscle that needs constant energy to keep beating
what are the reactants of respiration
oxygen and glucose
what are the products of respiration
water, carbon dioxide and energy
What is different about fermentation?
Fermentation doesn't require oxygen and it produces alcohol instead of water.
Explain how photosynthesis and cellular respiration are opposite processes
Photosynthesis requires the materials that respiration produces. Respiration requires the materials that photosynthesis produces. Photo. takes light energy to make food (glucose). Respiration takes food (glucose) to make chemical energy (ATP).
