|
Term
I can distinguish and compare the requirements and abilities of heterotrophs and autotrophs. |
|
Definition
Heterotrophs: Heterotrophs, like this eagle, feed off of other forms of life. photoheterotroph — obtains energy from light and must obtain carbon in an organic form chemoheterotroph — obtains energy from the consumption of organic molecules and an organic form of carbon Autotrophs:is an organism that produces complex organic compounds from simple inorganic molecules and an external source of energy, such as light or chemical reactions of inorganic compounds. An organism that obtains carbon from organic compounds but obtains energy from light is called a photoheterotroph, while an organism that obtains carbon from organic compounds but obtains energy from the oxidation of inorganic compounds is termed a chemoheterotroph.

|
Term
I can explain the role of the rubisco enzyme in the calvin cycle and photorespiration. |
|
Definition
Hooks up the Carbon and RUBP |
|
|
Term
I can define and describe the process of photorespiration. |
|
Definition
Photorespiration occurs when the CO2 levels inside a leaf become low. This happens on hot dry days when a plant is forced to close its stomata to prevent excess water loss. If the plant continues to attempt to fix CO2 when its stomata are closed, the CO2 will get used up and the O2 ratio in the leaf will increase relative to CO2 concentrations. http://www2.mcdaniel.edu/Biology/botf99/photodark/photorespiration.htm |
|
|
Term
I can explain the process of electron excitation in PSII and PS I. |
|
Definition
Electrons get excited and go to the electron acceptor and then go back down the ETP |
|
|
Term
I can describe the relationship between the Calvin cycle and the light reactions. |
|
Definition
The Calvin cycle uses the ATP and NADPH from the light reactions. |
|
|
Term
I can explain where in the chloroplast the light reactions occur. |
|
Definition
On the thylakoid membrane |

Term
I can explain what happens when a molecule is reduced. |
|
Definition
|
|
Term
I can explain what happens when a molecule is oxidized. |
|
Definition
|
|
Term
I can define and describe carbon “fixation”.. |
|
Definition
Carbon is fixed with RUBP by Rubisco |
|
|
Term
I can describe what happens to O2 and CO2 levels inside a leaf when stomata are closed. |
|
Definition
Photorespiration occurs because the CO2 levels are lower than normal and the O2 levels get higher |
|
|
Term

How do CAM plants avoid photorespiration? |
|
Definition
CAM plant avoid photorespiration by having another source of CO2 James Workman: --the four carbon acid that is built up at night when CAM plants keep their stomata open and they don't lose as much water |
|
|
Term
|
Definition
if a certain wavelength is reflected, that is the color that an object appear |
|
|
Term
What are xyloem and floem? |
|
Definition
xylem transports water from roots UP to leaves phloem transports carbs and other nutrients Ja |
|
|
Term
I can list and describe the types and function of major plant tissue types. |
|
Definition
Xyleom and phloem, xyleom is bigger |
|
|
Term
I can explain how H+ (protons) exit the thylakoid and what happens as a result. |
|
Definition
protons exit via ATP sythase (synthetase) and that "proton push power" causes the phosphrylation of ADP ==> AT |
|

Term
|
Definition
purple/blue light is in the 300 nm range green/yellow in the 500 nm range red/orange is in the 700 nm rang more energy the shorter the wavelengh |
|
|
Term
I can I can describe how H+ (protons) build up to high concentration levels inside the thylakoid. |
|
Definition
it is activvely transported by h+ ion(proton) pumping protein |
|
|
Term
I can describe how the action and absorption spectrums of photosynthesis are similar. |
|
Definition
plants reflect green light (that's why they look green) light that is reflected cannot power the light reactions J only light that is absorbed (not reflected) can power PSII and PSi so, whant that means, is the spectrum of light that is absorbed is extrememely similar to the spectrum of light that causes high rate of photosynthesi |
