QUIZ 3: HOW DO PLANTS WORK?
Jan Baptista's experiments showed:
loss of soil mass < gain of plant mass, gain of plant mass related to water
The first part of photosynthesis within the chloroplast occurs in the _____ and the second in the _____ of the chloroplast.
Grana, Stroma
Problems of world hunger are due to the green plant's inefficiency in food production.
False
Proteins are made directly from carbohydrates, the first products of photosynthesis.
False
What is respiration?
A decomposition reaction
A plant makes its own proteins but an animal synthesizes the proteins it consumes as food.
FALSE
Current populations experiencing famine are primarily the result of lack of land to grow more plants.
FALSE
Photosynthesis and respiration processes show plant cells to be very simple in design.
False
Photosynthesis consists of only the light reaction.
False
The first chemist to begin quantifying the process of photosynthesis was:
Nicholas de Saussure
The threadlike objects in the nucleus are called _____ and carry the _____ or inheritance units.
Not Spindle Fiber, Not Genes
What conditions and/or raw materials are necessary for photosynthesis to occur?
Not sure
Three important plant experimentation discoveries by scientists within the last 300 years are:
Oxygen comes from water molecules splitting, plants are associated with O2, Animals require O2, plant mass is related to H2O
Green plants are the energy link between the sun's energy and the energy needs of:
People
Plant respiration occurs:
Primarily at night
What factors speed up or slow down the rate of photosynthesis?
Temperature, Light, H2O
Why do animals and humans need proteins in their diet?
They break down protein into amino acids needed for their particular protein synthesis
The full use of the green plant's built-in design and potential has not yet been reached.
True
The building blocks of proteins are
amino acids
solar energy CO2 intake release of energy storage of energy release of O2 release of water ATP forms carbohydrates
light dark dark light light dark light dark
Green plants utilize solar energy through __________ and release energy through _________ .
photosynthesis, respiration
Priestly's experiments explained:
plants are associated with O2, animals require O2
The chemical energy stored in ATP during photosynthesis is used to:
produce a carbohydrate from CO2
The oxygen which is released into the air by a plant originates from:
splitting of water molecules
What is the function(s) of ATP?
stores the initial energy released by respiration, provides the energy for all cytoplasmic chemical synthesis
