How does photosynthesis benefit heterotrophs?
it creates food

The stage of respiration that releases most of the energy in glucose occurs in this cell organelle.
Mitochandria- mighty powerhouse

What captures energy from sunlight during photosynthesis?
chlorophyll and other pigments

Which of the following equations best represents photosynthesis?
6CO2+6H2O---->C6H12O6+6O2
or - 6C+6H2O--->C6H12O6
6CO2+6H2O---> C6H12O6+6O2

Plants use energy from the sun to produce _______ and sugars.
Oxygen
300
A __________ is an organism that cannot make its own food.
heterotroph
300
A ________ is an organism that can make its own food.
AUTOTROPH
300
Small openings called _________ allow CO2 to enter the leaf and O2 to exit.
stomata
300
Energy from glucose is released in the process of ________.
respiration
400
Chloroplast contain a special pigment known as ________.
Chlorophyll
400
Plants use energy from the sun to produce _________.
food energy
400
The energy releasing process that does not require O2 (oxygen) is known as _________.
Fermentation
400
Explain the following: Photosynthesis and respiration are opposite processes.
During photosynthesis, plants use carbon dioxide and water to produce sugars and oxygen. During respiration, oxygen combines with glucose to produce water and carbon dioxide.
400
During respiration molecules of ______ are 1st broken down in the cytoplasm.
glucose

Under which of the following conditions is lactic-acid fermentation most likely to occur?
a. a very fast run
b. a long walk
c. sleepin
a. a very fast run
500
What is the equation for Cellular Respiration?
C6H12O6 + 6O2 ➜ 6H2O + 6CO2 + 36 ATP (ENERGY)
Glucose + Oxygen ➜ Carbon dioxide + Water + Energy Released (ATP)
500
What is photosynthesis?
The process in which sunlight energy, h2o and co2 is converted into oxygen and energy for the cells.
500
Animals do not make their own food from energy in sunlight. Explain why they still depend on the sun for energy?
Animals depend indirectly on suns energy, plants use energy from the sun to produce sugars. Because animals cannot do this, they eat plants or other animals that eat plants. Without plants animals could not survive.
500
What would happen if photosynthesis did not occur?
All life would eventually die because plants provide us with energy and oxygen.
