Photoautoptroph |
Organisms that carry out photosynthesis. |
Acquires energy from light. Ex. Plants |
|
|
Photosynthesis |
Chemical reactions that uses light energy to produce organic compounds. |
3CO2+3H2O--------> C3H6O3+3O2 |
|
|
Pigments |
Natural coloring matter of animal or plant tissue. |
Ex. Chlorophyll Hemoglobin |
|
|
Thylakoids |
A sac like membrane in the chloroplasts of a plant cell that is arranged in stacks. |
In the mesophyll cells of a leaf. Contains chlorophyll. Inside is called lumen. Outside called stroma. |
|
|
Grana |
Stacks of thylakoid membranes. |
Production of starch takes place here. |
|
|
Stroma |
A mass of fungal tissue surrounding the grand inside the chloroplast. |
The Fluid between grana. A connective tissue in plants. |
|
|
Chloroplast |
A site that contains chlorophyll and in which photosynthesis takes place. |
Has stacks of discs inside called thylakoids. Traps energy from sunlight. |
|
|
Chlorophyll |
Green pigment found in all green plants, responsible for the absorption of light to provide energy for photosynthesis. |
Fat soluble. Produces carbohydrates. |
|
|
Light reactions |
The reaction that occurs as the first phase of photosynthesis. |
Takes place in the thylakoids membrane. Gives energy. |
|
|
Psi |
A protein complex involved in photosynthesis. |
Aka. Plastocyanin. |
|
|
Psii |
The first protein complex in the light dependent reactions of photosynthesis. |
Aka. Photo system II Located in thylakoid membrane of plants. |
|
|
Calvin cycle |
The set of chemical reactions that take place in chloroplast during photosynthesis. |
reaction Occurs in stroma. Uses products such as ATP to perform chemical processes. |
|
|
RuBP |
An organic substance that is involved in photosynthesis. |
Ribs lose-1,5-biphosphate |
|
|
NADP+/NADPH |
A cofactor used in anabolic reactions. NADP requires NADPH as a reducing agent. |
Is used in the Calvin cycle to reduce power. Is used to help turn carbon dioxide to glucose. |
|
|
ATP synthetase |
An important enzyme that provides energy for the cell to synthesize ATP. |
Present in chloroplasts,in plants. Integrates into thylakoid membrane. |
|
|
PGA/PGAI |
A chemical substance tag at is a metabolic used transitional in the Calvin cycle. |
3-Phosphoglyceric acid. A 3 carbon molecule. |
|
|
Rate |
A certain quantity or amount of one thing on relations to a unit of another thing. |
Ex rate of 60 mph |
|
|
Photoinhibition |
the inhibition of photosynthesis caused by protein damage. |
A light induces reduction. Blue light cause it more efficiently than othe wavelengths of visible light. |
|
|
Saturation point |
when no more of a susbstance can be absorbed. |
A solution in which no more solute can be dissolved has reached its ____________. |
|
|
Limiting factors |
Factors that limit the reaction rate in a process. |
Ex. Low Co2 can be the ___________ _________ of plant growth. |
|
|
Rubisco |
An enzyme present in plant chloroplast. |
Used in the Calvin cycle to catalyze the first step of carbon fixation. |
|
|
Photo respiration |
A respiratory process that takes up oxygen in the light and give up CO2. |
Occurs mainly In plants in the presence of light. A metabolic pathway. |
|
|
Bundle sheath cells |
A layer of cells in plant leaves and stems That forms a sheath around bundles of vascular tissue. |
Contains chloroplasts. Site of the Calvin cycle. |
|
|
C3 plants |
Plants most common at photosynthesis in cool climates . |
Goes through the Calvin cycle. Takes carbon dioxide through stomata. |
|
|
C4 plants |
Plant that uses c4 photosynthesis. |
Avoids photo respiration. Never saturate light under hot and dry conditions. |
|
|
CAM |
A carbon pathway that evolves in some plants. |
Usually occurs in plants that are found in deserts. |
|
|
Stomates |
Pores in the epidermis of a leaf. |
Forms a silt. Allows gasses through. |
|
|
Chemoautotrop |
An organism that carries out chemosynthesis for energy. |
Gets energy by oxidation. Ex. Bacteria |
|
|
Chemosynthesis |
Chemical reactions using chemical energy to produce organic compounds. |
12HS+6CO2----------> C6H1206+6H20+12S. Tube worms rely on this reaction to survive. |
