Biology Quiz 3: How Do Plants Work?

The building blocks of proteins are

amino acids

anaerobic glycolysis

Pick the correct answer from each drop-down menu to complete the reaction for photosynthesis.

Carbon Dioxide Water Light Glucose Oxygen

The electron transport of respiration occurs in organelles called

mitochondria

Which organelle is responsible for producing energy by the Krebs cycle?

mitochondria

Hill is known for working out reactions taking place during the ___________of photosynthesis.

light reaction

Enzymes are:

proteins

What are the waste products of respiration?

H 2O CO 2

Which conditions relate to the research of Van Helmont? plant was grown outside in the ground plant mass only comes from the soil conclusions partly correct around 1400 A.D. plant mass related to H 2O

conclusions partly correct plant mass related to H 2O

Since carbon as an atmospheric gas is locked into a food molecule, it is termed carbon dioxide fixation. Another name for this process of photosynthesis is the

dark reaction

Jan Baptista's experiments showed:

loss of soil mass < gain of plant mass gain of plant mass related to water

The twenty two amino acids are capable of producing _______________.

millions of different proteins

The width of a tree increases through direct growth of the:

vascular cambium

A dicot may be expected to have:

vascular rings netted veins

The oxygen which is released into the air by a plant originates from:

splitting of water molecules

Pick the best answer from each of the drop-down menus below to complete the reaction for photosynthesis.

Carbon Dioxide + Water ------> Glucose + Carbon Dioxide + Water

The inevitable process causing increase in ________ in the universe and loss in useful energy is called entropy.

disorder

Choose from the following list the three stages of respiration which convert food to useful energy.

electron transport chain glycolysis Krebs cycle

The _______ requirements of all organisms worldwide are linked to the sun by photosynthesis.

energy

Where do plants obtain the oxygen necessary to utilize foods?

from the atmosphere

The first stage in the decomposition of glucose is called

glycolysis

Joseph Priestly discovered that plants give off, or release _____ to the atmosphere.

oxygen

The chemical energy stored in ATP during photosynthesis is released during the dark phase to:

produce a carbohydrate from CO 2

Match the associations with the "light" and "dark" phases of photosynthesis: solar energy CO2 intake release of energy. storage of energy. release of O2. release of water. ATP forms carbohydrates

solar energy -light CO2 intake -dark release of energy.- dark storage of energy.- light release of O2.-light release of water.-dark ATP - light forms carbohydrates - dark

Van Niel's theory, later shown to be correct, claimed that the oxygen produced by photosynthesis comes from the

splitting of the water molecule

What is the function(s) of ATP?

stores the initial energy released by respiration provides the energy for all cytoplasmic chemical synthesis
