Answer 3

Chlorophyll

Question 4

Found mainly in the mesophyll layer of ground tissue in plant leaves.

Answer 4

Chlorophyll

Question 5

Thylakoid, Grana, Stroma

Answer 5

Chloroplast#structure#

Question 6

Little green discs that contain the pigment chlorophyll found inside the chloroplast.

Answer 6

Thylakoid

Question 7

Site of the light reaction of photosynthesis. It’s primary purpose is to make ATP and NADPH

Answer 7

Thylakoid

Question 8

a stack of thylakoids

Answer 8

Grana

Question 9

watery space surrounding the thylakoids and use ATP and NADPH to make sugars using CO2.

Answer 9

Stroma

Question 10

Photosynthesis Chemical Reaction

Answer 10

• Starts by taking sunlight energy and converting it into chemical energy (ATP & NADPH)
• Then takes the chemical E (ATP and NADPH) and uses that chemical energy to power the production of sugar

Question 11

Photosynthesis Equation

Answer 11

6CO2+6H2O –> C6H12O6+6O2+Heat

Question 12

Two processes involved in the conversion of sunlight energy to sugar

Answer 12

Light reaction and Calvin cycle

Question 13

light independent reaction–Makes sugar using CO2, ATP, and NADPH

Answer 13

Calvin cycle

Question 14

light dependent-It changes sunlight into ATP and NADPH (Usable chemical energy)

Answer 14

Light reaction

Question 15

Sunlight travels through ___ with different _____.

Answer 15

waves, wavelengths

Question 16

longest wavelength

Answer 16

Red light

Question 17

shortest wavelength

Answer 17

Question 18

measures light wavelengths not absorbed by a specimen

Answer 18

Spectrophotometer

Question 19

shows all the Wavelengths/colors found in sunlight

Answer 19

electromagnetic spectrum

Question 20

Light travels in units of Energy called

Answer 20

Photons

Question 21

hese colors are usable light-Plants use Reds and Blues; but not green

Answer 21

Absorbed

Question 22

Main pigment found in all plants and algae.

Answer 22

Chlorophyll A

Question 23

Helps Chlorophyll A receive sunlight E

Answer 23

Chlorophyll B

Question 24

These are accessory pigments that help Chlorophyll A - these are orange or yellow pigments

Answer 24

Carotenoids

Question 25

group of light absorbing pigments in thylakoid membrane

Answer 25

Photosystem

Question 26

These colors are not usable

Answer 26

Question 27

Happens in cytoplasm. Everything that has cytoplasm can go through this process.

Answer 27

Glycolysis

Question 28

Creates/Provides electron carriers

Answer 28

Kreb’s Cycle

Question 29

In this process electrons move two at a time toward oxygen

Answer 29

ETC - the electrons move down the ETC too

Question 30

The final electron acceptor in ETC

Answer 30

Oxygen

Question 31

Electron carriers

Answer 31

NADH & FADH2
