|
Photoautotroph |
An organism that gets its energy through light energy through a process known as photosynthesis. |
Plants are this. What does Photo mean? |
|
|
Photosynthesis |
Photosynthesis is a series of chemical reactions that employs light energy to take CO2 and H2O, and convert it into O2 and sugars. |
Plants use this process. Photo+Synthesis? Photo means? Synthesis means? |
|
|
Pigments |
Chemicals in photosynthetic cells that have the ability to absorb wavelengths on the visible light spectrum. |
This is not painting pigment. When something reflects a color, what happens to the rest of the color? |
|
|
Thylakoid |
Flattened sacs inside of the chloroplast that contain the chlorophyll. |
They contain pigmented what? One part of the cytoplast. |
|
|
Grana |
The stacks that the thylakoids are arranged in. |
They are certain patterns that the chlorophyll holders are arranged in. Look like pancakes |
|
|
Stroma |
A liquid solution outside of the thylakoid that allows light in. |
It's like cytoplasm, in a way. What is between the stacks? |
|
|
Chloroplast |
The site of photosynthesis in a plant. |
What makes up a plant? Primary energy factory. |
|
|
Chlorophyll |
A green pigmented molecule that absorbs light for energy purposes. |
Why does it reflect green? Inside of the thylakoid. |
|
|
Light Reactions |
Reactions that happen inside of the thylakoid to produce energy for the plant, ex: NAPDH |
What is photosynthesis? What happens to the light absorbed by the chlorophyll. |
|
|
PSI |
Photosystem 1. It is located on the outside of the grana and primarily functions to produce ATP. |
|
|
|
PSII |
Photosystem 2, located inside of the thylakoid membrane. Absorbs shorter wavelengths, responsible for ATP and hydrolysis of water. |
It is not located on the outside. |
|
|
Calvin Cycle |
The chemical reactions that take place inside of the chloroplast to create energy. |
The means by which photosynthesis is possible. Similar to cellular respiration. |
|
|
RuBP |
Ribose Biphosphate, a five carbon sugar that is combined with CO2 in the first stages of photosynthesis. |
|
|
|
NADP/NADPH |
Nicotinamide adenine dinucleotide phosphate, a coenzyme in many living things that functions as an electron receptor. |
This functions ad an electron _____. C21H28O7N14P3. |
|
|
ATP Synthase |
An enzyme that gives energy to the cell via synthesis of ATP. |
Commonly referred to as cell currency. Synthase sounds like? |
|
|
PGA/PGAL |
A 3 Carbon molecule that is produced by the Calvin Cycle. |
Produced by the primary source of photosynthesis. Also produced in glycolysis. |
|
|
Rate |
How quickly the photosynthetic process produces sugar. |
General meaning of rate? How quickly can one of the results of photosynthesis be produced? |
|
|
Photoinhibition |
When photosynthesis is inhibited due to protein damage caused by too much light, or the wrong kind of light. |
Light can cause damage because? Inhibition means? |
|
|
Saturation point |
The point in a solution where a substance will not take any more of a substance. |
What does saturation mean? It cannot keep taking water forever. |
|
|
Chemosynthesis |
A set of chemical reactions where inorganic substances are oxidized with CO2 in order to make sugars. |
A generally inefficient way of making energy, used as evolution's last resort. Used when there is no sunlight and nothing to eat, last energy source. |
|
|
Limiting Factors |
Factors in the environment that keep organisms from reaching their full biological potential. |
Intensity of sunlight. Too much rain. |
|
|
Rubisco |
An enzyme that aids in the process of fixing atmospheric carbon dioxide. |
In the process of photosynthesis. What needs to happen to carbon dioxide? |
|
|
Photorespiration |
A process where a plant takes in sun energy, and gives off oxygen. |
We need this to breath. The end result of photosynthesis. |
|
|
Bundle Sheath cells |
A series of cells in stems and leafs that form a sheath around vascular bundles. |
It is in the name. The plant wall is similar to this. |
|
|
C3 Plants |
Plants that function best in moist, cold climates. |
These would probably be in temperate areas. Pine Trees |
|
|
C4 Plants |
Plants that function best in hot, dry climates. |
This might be a cactus. Desert or summer climates. |
|
|
CAM |
Crassulacean acid metabolism. A carbon fixation pathway in plants. |
Succulents Has to do with metabolism. |
|
|
Stomates |
A tiny pore in the surface of a plant that serves gas exchange. |
The gateway to ________. Has to do with air. |
|
|
Chemoautotroph |
When an organism gets energy from inorganic substances that are oxidized in the presence of CO2. |
Chemo+synthesis means? These include bacteria in areas that are otherwise not suited for life. |
