Q

What color in the spectrum is most visible?

A

green

2
Q

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

A

50%

3
Q

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

A

MORE

4
Q

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

A

LESS

5
Q

Absorption of colors from most to least visible

A

green, yellow, orange, red, blue, violet

6
Q

What colors absorb the most light?

A

red, blue, violet

7
Q

What kind of energy comes from the sun?

A

electromagnetic radiation

8
Q

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

A

small waves=more energy=more dangerous

long waves=low energy=less dangerous

9
Q

What enters the leaf?

A

Co2, sunlight, water

10
Q

What exits the leaf?

A

O2, water, sugar

11
Q

In what form does water enter and exit the leaf?

A

Enters as a liquid, exits as a gas

12
Q

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

A

Co2 and water

Enter through the underside

13
Q

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

A

Sugar and oxygen

Leave through the underside

14
Q

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

A

Palisade mesophyll

15
Q

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

A

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

16
Q

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

A

Upper cuticle and upper epidermis

17
Q

Palisade mesophyll vs. other parts of the leaf

A

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

18
Q

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

A

Greater SA means more photosynthesis happens

19
Q

What is the purpose of the waxy layer?

A

Contain water inside the plant

20
Q

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

A

Stoma
Opening for underside
Stroma covered it

21
Q

What gases are found in the air spaces?

A

Co2, oxygen, water vapor

22
Q

Process of photosynthesis

A

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.
