Photosynthesis

Question 1

make their own food from sunlight or chemical bonds in organic substances

Answer 1

autotroph

Question 2

examples of autotrophs

Answer 2

trees, grass, algae, and methanogenic archae

Question 3

must eat other organisms in order to obtain energy

Answer 3

heterotrophs

Question 4

examples of heterotrophs

Answer 4

humans, insects, fungi

Question 5

indirectly dependent on the sun’s energy through photosynthesis

Answer 5

heterotrophs

Question 6

photosynthesis equation

Answer 6

6CO2 + 6H20 → C6H12O6 + 6O2

Question 7

reactants of photosynthesis

Answer 7

carbon dioxide and water

Question 8

products of photosynthesis

Answer 8

oxygen and glucose

Question 9

biochemical pathway

Answer 9

a series of chemical reactions within cells
-the product of one reaction is consumed by the next reaction

Question 10

example. bacteria

Answer 10

prokaryotic

Question 11

always unicellular

Answer 11

prokaryotic

Question 12

no nucleus

Answer 12

prokaryotic

Question 13

no membrane bound organelles like chloroplast of mitochondria

Answer 13

prokaryotic

Question 14

ex. plants and animals

Answer 14

eukaryotic

Question 15

can me multicellular

Answer 15

eukaryotic

Question 16

has a nucleus

Answer 16

eukaryotic

Question 17

has membrane bound organelles

Answer 17

eukaryotic

Question 18

PLANT ONLY: cell wall and chloroplasts

Answer 18

eukaryotic

Question 19

pigment

Answer 19

a compound that absorbs the light

Question 20

chlorophyll a

Answer 20

-absorbs less blue light but more red light than chlorophyll b
-directly involved in light reactions

Question 21

chlorophyll b

Answer 21

-assessory pigments
-not directly involved in photosynthesis

Question 22

products of light reactions

Answer 22

-oxygen is released into the environment
-ATP
-NADPH

Question 23

where do light reactions take place

Answer 23

in the thylakoid membrane of the grana within the chloroplast

Question 24

CAM pathways

Answer 24

-closed stomata during the day and open during the night
-survive in dry climates because plants need even less water than C4
-ex. cactus and pineapple

Question 25

C4 pathways

Answer 25

-partially closed stomata during the hottest part of the day
- corn, sugar cane, and crab grass

Question 26

calvin cycle

Answer 26

uses the products of the light reactions to produce organic compounds.
-uses a process called carbon fixation - adding of CO2

Question 27

products of the calvin cycle

Answer 27

sugar, NADP+, ADP

Question 28

reactants of the calvin cycle

Answer 28

carbon dioxide, ATP, NADPH

Question 29

where does the calvin cycle take place

Answer 29

the stroma of the chloroplast
