Photosynthesis

Front 1

Where does most of the energy used by life on Earth come from?

Back 1

The Sun

Front 2

What is the difference between autotrophs and Heterotroph?

Back 2

Autotrophs make their own food
Heterotroph eat organic material

Front 3

What is the difference between producers and consumers?

Back 3

Producers make their own food
Consumers eat organic compounds

Front 4

What types of organisms can carry out photosynthesis?

Back 4

Plants, algae, and some prokaryotes

Front 5

In the process of photosynthesis, what is light energy converted to?

Back 5

Chemical energy (food)

Front 6

What is the equation for photosynthesis?

Back 6

6CO2 + 6H2O - - -(sunlight) - - - > C6H12O6 + 6O2+H20

Front 7

What is the gas released into the atmosphere during photosynthesis?

Back 7

Oxygen

Front 8

In what organelle does photosynthesis occur?

Back 8

Chloroplast

Front 9

What is the space inside the inner membrane called?

Back 9

Stroma

Front 10

What are stacks of thylakoids called?

Back 10

Grana

Front 11

Where in the chloroplast is the chlorophyll located?

Back 11

It's arranged around photosystems which are embedded into the thylakoid (in the thylakoid)

Front 12

What pigment traps energy from the Sun?

Back 12

Chlorophyll

Front 13

What happens to the rate of photosynthesis as light intensity increases?

Back 13

It gradually increases until it hits 500 then it plateaus

Front 14

What happens to the rate of photosynthesis as carbon dioxide concentration increases?

Back 14

It increases steeply then gradually backs off

Front 15

Describe a relationship of temperature with the rate of photosynthesis

Back 15

It looks like a rainbow it peaks at 25 degrees Celsius

Front 16

What are guard cells? What is their function?

Back 16

Cells surrounding each stoma. They help regulate the rate of carbon dioxide entering, and transpiration by opening and closing the stomata.

Front 17

What enters and leaves through the stomata?

Back 17

Carbon dioxide enters
Water and oxygen leave

Front 18

Which condition which would result in the higher rate of transpiration: light or dark?

Back 18

Light, because stomata are usually open in the light and solar energy increases evaporation

Front 19

Which condition would result in the higher rate of transpiration: humid an environment or dry environment?

Back 19

A dry environment because the water potential would be so low it would cause more rapid evaporation

Front 20

Which condition would result in the higher rate of transpiration: breezy conditions or still air?

Back 20

Breezy conditions would increase the evaporation of water from the surface of the leaves, lowering the water potential, and resulting in a more rapid evaporation. However, if the plan is subjected to very high wind movement, the stomata may close which will prevent water loss.

Front 21

Which condition would result in the higher rate of transpiration: hot environment or warm environment?

Back 21

It depends on the plant. Usually however, unless the plant is adapted to hot environments, the rate of transpiration will drop because heat stress may cause the stomata to close, which conserves water.

Front 22

What can happen to light?

Back 22

Light can be absorbed, reflected, or transmitted.

Front 23

What make something appear specific color?

Back 23

Other colors are being absorbed. That color is being reflected

Front 24

What happened to the components of water molecules when water is split in the light reactions?

Back 24

1. H+ go through the electron transport chain, producing ATP which goes to the Calvin cycle
2. The electrons move to photosystem 2
3. O2 is released

Front 25

What causes electrons in the photosystems of a chlorophyll molecule in the light reactions of photosynthesis to be transferred to an electron carrier?

Back 25

Light raises electrons to higher energy levels

Front 26

What is needed to excite electrons to higher energy levels?

Back 26

Light

Front 27

What is occurring in the dark reactions of photosynthesis?

Back 27

CO2 is converted to organic compounds (sugar)

Front 28

What products from the light reactions are needed for carbon fixing to be able to occur in the light independent reactions of photosynthesis?

Back 28

NADPH and ATP

Front 29

In what organelle does cellular respiration occur?

Back 29

Mitochondria

Front 30

What is the equation for cellular respiration?

Back 30

C6H12O6 + CO2 - - - - - > 6CO2 + 6H2O + ATP

Front 31

Which gas is released into the atmosphere during the process of cellular respiration?

Back 31

Carbon dioxide

Front 32

What happens when cells break down food molecules?

Back 32

They're temporarily stored in ATP

Front 33

What happens when a phosphate group is removed from an ATP molecule?

Back 33

It releases energy and becomes ADP

Front 34

What occurs in glycolysis?

Back 34

6 glucose split into 2, 3 pyruvate molecules

Front 35

Describe the relationship of glycolysis to aerobic and anaerobic respiration

Back 35

Glycolysis doesn't need O2, but occurs as both apart of aerobic respiration and anaerobic respiration pathways.

Front 36

What is involved in aerobic respiration?

Back 36

Glycolysis and Krebs cycle

Front 37

What is the final electron acceptor in the electron transport chain of aerobic respiration?

Back 37
