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
