Photosynthsis

Question 0

Stomates

Answer 0

Opens and closes to regulate movement of water vapor/gas exchange of leaf with guard cells which swell with water to open and close

Question 1

Cuticle

Answer 1

Waxy leaf covering for protection/prevents excess water loss

Question 2

Palisade mesophyll

Answer 2

Where most photosynthesis/chloroplasts occur in a leaf

Question 3

Spongy layer

Answer 3

Lots of air space b/c of irregular shapes to allow gas exchange

Question 4

Veins

Answer 4

Contain vascular tissue

Question 5

Xylem

Answer 5

Veins carrying water and minerals (UP only)

Question 6

Phloem

Answer 6

Veins carrying nutrients (ALL directions)

Question 7

What do root hairs do?

Answer 7

Increase surface area for greater absorption

Question 8

Root pressure

Answer 8

Osmotic pressure in xylem of a root

Question 9

Transpiration

Answer 9

Evaporation of water off leaves

Question 10

Pigment definition and 3 examples?

Answer 10

Substance that absorbs certain wavelengths/reflect others to create color e.g chlorophyll (green), carotenes (orange), and xanthophylls (yellow)

Question 11

What is the process of separating pigments called and how can we separate them?

Answer 11

Chromatography with chromatography paper; more soluble move up, less soluble stay down

Question 12

Photons

Answer 12

Packages of light energy

Question 13

White light

Answer 13

Made of a spectrum of colors

Question 14

Photosynthesis equations

Answer 14

6CO2+12H2O+sunlight»C6H12O6+6O2+6H2O inorganic to organic

Question 15

Coenzyme of photosynthesis

Answer 15

NADP+H (oxidized version)

NADPH (reduced version)

Question 16

Redox

Answer 16

Oxidation and reduction occurring at the same time

Question 17

Where do light reactions take place?

Answer 17

Grana (“photo” part of photosynthesis)

Question 18

Where do light independent reactions take place and what are thee names for them?

Answer 18

Stroma; carbon fixation, dark reactions, Calvin cycle

Question 19

Light dependent reaction, what occurs?

Answer 19

H2O is split through photolysis, O2 released, H reduces the NADP to NADPH, ATP is made

Question 20

Dark reactions, what occurs?

Answer 20

Enzyme Rubisco converts inorganic CO2 into organic glucose by combining 2 PGAL molecules (a 3 C molecule) using ATP from light reaction..waste products are NADP+ and ADP+P

Question 21

Reactants and products of light dependent?

Answer 21

Reactants: H2O sunlight NADP+
ADP+P
Products: ATP O2 NADPH

Question 22

Reactants and products of light INNdependent?

Answer 22

Reactants: CO2 ATP NADPH
Products: C6H12O6 ADP+P NADP+

Question 23

Photolysis

Answer 23

Breaking up of H2O in O2+H using sunlight

Question 24

Rubisco

Answer 24

Enzyme that converts PGAL and CO2 into C6H12O6
