Photosynthesis Guided Reading!
...
During the process of photosynthesis, what energy do plants use to make food?
Sunlight.
The green pigment in chloroplasts that absorb light energy from the sun.
Chlorophyll.
What does the cell need to make sugar?
Energy from the sun, water, and carbon dioxide.
What are the products of photosynthesis?
Oxygen and Sugar.
What is the chemical equation for the process of photosynthesis?
6CO2 (Carbon Dioxide) + 6H2O (Water) - C6H12O6 (Glucose) + 6O2 (Oxygen)
What are the raw materials or reactants of the process of photosynthesis?
Carbon Dioxide and Water.
What do plant cells use for food and then store it in plant cells for later use?
Sugar.
Sugar is made into other compounds such as..
Cellulose.
Extra sugar molecules pass out of the plant through what?
The Stomata.
An autotroph thats energy is directly from the sun.
Plants.
A heterotroph that's energy is indirectly from the sun.
Caterpillars and Blue Birds.
What does photosynthesis produce that most living things need to survive?
Oxygen.
An organism that makes its own food.
Autotroph.
An organism that cannot make its own food.
Heterotroph.
Respiration Guided Reading!
...
Cells store energy in the form of what?
Carbohydrates.
What is the respiration chemical equation?
6CH12O6 (Glucose) + 6O2 (Oxygen) - 6CO2 (Carbon Dioxide) + 6H2O (Water) + Energy.
What do plants produce that animals use?
Oxygen.
What do animals produce that plants use?
Carbon Dioxide.
An energy releasing process that does not require oxygen. It provides energy for the cells without using oxygen.
Fermentation.
Does fermentation release more or less energy than respiration?
Less.
Nitrogen Cycle Notes!
...
Once the nitrogen gas has been fixed into nitrates and ammonia, it is absorbed by plants and moved through the food web as amino acids and protein.
Assimilation.
When a living organism dies bacteria and fungi break down the tissue which produces ammonia. This ammonia will either be reabsorbed by a plant, dissolve into water, or go into the soil.
Decomposition.
The ammonia that goes back into the soil from decomposition is nitrified by bacteria into nitrates and nitrites. This happens only in the presence of oxygen. These nitrates and nitrites can be absorbed by plants or stay in the soil.
Nitrification.
The nitrates and nitrites that are left in the soil from nitrification are then consumed by denitrifying bacteria which convert the nitrates and nitrites back into nitrogen gas through a process thats without oxygen. This completes the cycle.
Denitrification.
Fixing the Nitrogen Gas in the atmosphere into something that is usable by living things. This can happen in 3 ways. Atmospheric, Biologic, and Industrial.
Fixation.
Makes up the majority of all nitrogen gas that is “fixed”. Bacteria on the roots of plants or in the soil take in the nitrogen gas between soil particles and transform the nitrogen gas into nitrates and ammonia
Biologic Fixation.
The energy from lighting forces the nitrogen gas and oxygen gas in the atmosphere to bond, forming nitrates that fall to earth.
Atmospheric Fixation.
This is a human-made procedure called Haber’s Process which combines nitrogen gas and hydrogen gas under pressure and heat to create ammonia.
Industrial Fixation.

...
What is one consequence of an algal bloom?
Depletion of oxygen levels in bodies of water.
What is the role of the nitrifying bacteria?
Converting ammonia into nitrites and nitrates.
Haber's Process.
Nitrogen combines with hydrogen and oxygen to form ammonia.
