Photosynthesis Quiz 1

Question 1

What color in the spectrum is most visible?

Answer 1

green

Question 2

Everything above _% of light energy reflected is visible to the human eye

Answer 2

50%

Question 3

If more energy is reflected is it more or less visible?

Answer 3

MORE

Question 4

If more energy is absorbed is it more or less visible?

Answer 4

LESS

Question 5

Absorption of colors from most to least visible

Answer 5

green, yellow, orange, red, blue, violet

Question 6

What colors absorb the most light?

Answer 6

red, blue, violet

Question 7

What kind of energy comes from the sun?

Answer 7

electromagnetic radiation

Question 8

What size waves does high and low energy come in? Which is more dangerous?

Answer 8

small waves=more energy=more dangerous

long waves=low energy=less dangerous

Question 9

What enters the leaf?

Answer 9

Co2, sunlight, water

Question 10

What exits the leaf?

Answer 10

O2, water, sugar

Question 11

In what form does water enter and exit the leaf?

Answer 11

Enters as a liquid, exits as a gas

Question 12

What are the reactants for photosynthesis? How do they enter the leaf?

Answer 12

Co2 and water

Enter through the underside

Question 13

What are the products of photosynthesis? How do they leave the leaf?

Answer 13

Sugar and oxygen

Leave through the underside

Question 14

What kinds of cells have chloroplasts? Where does photosynthesis take place?

Answer 14

Palisade mesophyll

Question 15

How does the placement of the veins help transport materials to and from the leaf?

Answer 15

Water and sugar are close to the veins and can easily go in and out of the cell

Question 16

What layers does the light energy travel to reach the palisade mesophyll?

Answer 16

Upper cuticle and upper epidermis

Question 17

Palisade mesophyll vs. other parts of the leaf

Answer 17

PALISADE MESOPHYLL: bigger, more SA, cylindrical, towards the top, compact
OTHER: spherical, towards the bottom, has holes/pores

Question 18

How does the shape of the palisade mesophyll increase the amount of photosynthesis taking place?

Answer 18

Greater SA means more photosynthesis happens

Question 19

What is the purpose of the waxy layer?

Answer 19

Contain water inside the plant

Question 20

What is found between guard cells? Where is it? How does this help the leaf retain water in dry conditions?

Answer 20

Stoma
Opening for underside
Stroma covered it

Question 21

What gases are found in the air spaces?

Answer 21

Co2, oxygen, water vapor

Question 22

Process of photosynthesis

Answer 22

Water enters through the roots, into the veins, and into palisade mesophyll. Co2 comes through underside and into stoma, spongy layer and palisade mesophyll. In the palisade mesophyll the oxygen and sugar are made. Sugar goes into veins and thought the plant. Then sugar goes through cell respiration.
