What is photosynthesis
the synthesis of organic compounds by bacteria or other living organisms using energy derived from reactions involving inorganic chemicals, typically in the absence of sunlight.
the process by which green plants and some other organisms use sunlight to synthesize foods from carbon dioxide and water.
Photosynthesis in plants generally involves the green pigment chlorophyll and generates oxygen as a byproduct.
All use photosynthesis except
plants
algae
cyanobacteria
sulfur bacteria
Byproduct of photosynthesis
glucose
oxygen
carbon dioxide
water
How does carbon dioxide affect photosynthesis?
is taken in by the plant along with water and sunlight
plants produce it
produces ATP (Adenosine Triphosphate)
is taken in by the plant along with water, sunlight, and oxygen
Select all that apply to chloroplasts
just like a cell wall, it is also found in bacteria
is a green pigment
contains chlorophyll
Have 2 membranes ( A bi-bilayer)
Select all that apply to a thylakoid
Is the inner membrane in the chloroplast
Is folded and looks like stacks of coins called granum or grana
Is where the Light-DEPENDENT or light reactions of photosynthesis takes place
Is where the Light-INDEPENDENT or light reactions of photosynthesis takes place
What is the stroma
Is the space surrounding the granum (pancake like stacks)
The inner membrane of the chloroplast
contains starch, chloroplast DNA and ribosomes, as well as all the enzymes required for light-INDEPENDENT reactions
contains starch, chloroplast DNA and ribosomes, as well as all the enzymes required for light-DEPENDENT reactions
Select all that apply to Light-dependent reactions
Happen only in sunlight
Light is absorbed by chlorophyll molecules
The energy generates molecules of ATP
Also known as the Calvin cycle
Select all that apply to light-independent reactions
Happens in the light and dark
Also known as Calvin cycle
Monosaccharides are used to build polysaccharides (STARCH)
Happens only in the dark
What is the equation for photosynthesis
6CO2 + 6H2O >>SUN>> C6H12O6 + 6O2
6C2O + 6HO2 >>SUN>> C12H6O12 + 6O2
What are the REACTANTS involved in the process of photosynthesis
6CO2 (Carbon dioxide)
C6H12O2 (Glucose)
6H2O (Water)
6O2 (Oxygen)
What are the PRODUCTS involved in the process of photosynthesis
6CO2 (Carbon dioxide)
C6H12O2 (Glucose)
6H2O (Water)
6O2 (Oxygen)
What are autotrophs?
A group of organisms that go through photosynthesis to make their own food
A group of organisms that go through chemosynthesis
Organisms that DO NOT make their own food
plants, algae, and cyanobacteria
What are chemotrophs?
A group of organisms that go through chemosynthesis
Organisms that DO NOT make their own food
A group of organisms that go through photosynthesis to make their own food
Archea bacteria
What are Heterotrophs?
A group of organisms that go through photosynthesis to make their own food
A group of organisms that go through chemosynthesis
Organisms that DO NOT make their own food
Consumers
How much energy is transferred from each trophic level
10%
100%
1%
0.1%
Select all that apply to food chains
Includes decomposers at every trophic level
Includes producers(autotrophs)
Includes primary consumers(herbivores)
includes 2nd and tertiary consumers
Decomposers at the end of the chain
Select all that apply to food webs
Most organisms eat more than just one organisms
Complex and diverse organisms at every trophic level
Arrows point in the direction of energy transfer
Simple and direct
