Chapter 6

Question 1

potential energy

Answer 1

stored energy

Question 2

photosynthesis

Answer 2

pieces by which plants and other autotrophs use the energy of sunlight to make energy rich molecules using calcium dioxide and water

Question 3

photons

Answer 3

packets of light energy

each with a specific wavelength and quantity of energy

Question 4

light energy

Answer 4

energy of the electromagnetic spectrum of radiation that is visable to the human eye

Question 5

kinetic energy

Answer 5

energy of motion or movement

Question 6

chlorophyll

Answer 6

pigment present in the green parts of plants that absorbs photons of light energy during the “photo” reactions of photosynthesis

Question 7

carbon fixation

Answer 7

conversion of inorganic carbon (CO2) into organ forms (sugar)

Question 8

autotrophs

Answer 8

organisms that captures the energy of sunlight by photosynthesis

Question 9

heterotrophs

Answer 9

organisms that obtain energy by eating organic molecules that were produced by other organisms

Question 10

chloroplast

Answer 10

organelle in plant and algae cells where photosynthesis occurs

Question 11

heat

Answer 11

the kinetic energy generated by random movements of molecules or atoms

Question 12

chemical energy

Answer 12

potential energy stored in the bonds of biological molecules

Question 13

biofuels

Answer 13

renewable fuels made from living organisms (i.e. plants and algae)

Question 14

ATP

Answer 14

adenosine triphosphate
molecule that cells use to power energy-requiring functions
the cell’s energy “currency”
