Total questions: 20
Worksheet time: 10mins
We call the first phase of photosynthesis the light dependent reactions
True
False
This is the photosynthesis equation: CO2 + H2O = C6H12O6 + O2
True
False
Green plants are the only autotrophs in existence.
True
False
Which organelle is responsible for conducting photosynthesis?
Cell Wall
Mitochondria
Chloroplasts
All of these do photosynthesis
An advantage of being an autotroph is their ability to...
Make their own food
Create CO2 from glucose
Create energy from sunlight
Make their own food AND Create energy from sunlight
A process by which organisms use light to make their food, storing the light as chemical energy in the form of sugar. 6CO2 + 6H2O + energy -> C6H12O6 + 6O
Cholorophyll
Electron Transport Chain
Chemosynthesis
Photosynthesis
What is the pigment in chloroplasts that performs photosynthesis and also makes the leaf appear green?
Chlorosynthesis
Chlorophyll
ADP
Electron Transport
Which of the following is a product of photosynthesis?
Oxygen
Glucose
Carbon Dioxide
Oxygen AND Glucose
Photoautotrophs put ATP together using...
light energy
chemical energy
digestive enzymes
moon energy
Where do the light dependent and independent reactions of photosynthesis occur?
Thylakoid and Outer Membrane
Outer Membrane and Stroma
Thylakoids and Stroma
None of these
The second half of photosynthesis is often called...
Calvin Cycle
Stage 2
Light Dependent Reactions
All of the above
Chloroplasts are often found in which kinds of cells?
Plant
Animal
Neither
Both
During the light dependent reactions, solar energy is used to split H2O molecules. During this process, a photosynthesizing organism accidentally creates which product?
CO2
O2
C6H12O6
Glucose
What are the reactants in the photosynthetic equation?
O2 and H2O
CO2 and C6H12O6
C6H12O6 and H2O
CO2 and H2O
What molecule is responsible for things like muscle contractions, cellular communication, provides energy for every day tasks, and can be likened to a fully charged battery?
ATP
ADP
Chlorophyll
Granum
Why do organisms want to perform photosynthesis?
To make H2O from CO2
To create much needed O2
To make food in the form of glucose
To create CO2
Where in the ATP molecule is the most energy stored?
the bonds between the phosphate groups
the bond holding the adenosine to the first phosphate group
the bond between the two cyclic structures
there is no energy stored in ATP
Where do plants get their carbon from, to build their own carbon compounds within their cells?
from inorganic carbon dioxide in the atmosphere
from the food they consume
from the water they get through the roots
from the oxygen that humans exhale
The prefix “chemo” means
chemical
bacteria
carbon
light
A heterotroph must take in organic sources of carbon and break them down to make their own compounds. Heterotrophs are also referred to as…
producers
consumers
chemical producers
autotrophs
