Term
Autotrophs
Definition
an organism capable of synthesizing its own food
Term
Photosynthesis

transpiration
Term
Cuticle
Definition
redirects water to roots
Term
Palisade Layer
Definition
where chloroplasts and photosynthesis occur
Term
Stomata
Definition
hole in lower epidermis of leaf that takes in CO2 gives off O2
Term
Spongy Mesophyll
Definition
where gases are stored
Term
Pedicel
Definition
connects the stem to the flower
Term
Xylem
Definition
carries water up a plant using capillary action
Term
Phloem
Definition
carries food up a plant using capillary action
Term
Flower
Definition
reproduction
attracts insects
Term
complete/ perfect flower

both male and female
Term
imperfect (pistillate)
Definition
only female
Term
Sepal
Definition
bud formed where flower closes
Term
Pedia
Definition
connects leaf to stem
Term
Pigment
Definition
light absorbing chemical that is specific to different wave lengths
Term
Chlorophyll
Definition
principal pigment of plants
absorbs light in blue-violet and red but not green- green is reflected
Term
Color
Definition
specific wavelengths of light
Term
Light
Definition
mixture of different wavelengths of light
Term
Photon
Definition
take on wave like property
Term
Wave Length
Definition
distance between adjacent crests
Term
Wave Frequency
Definition
number of crests past a fixed point
(seconds)
Term
Wave Amplitude
Definition
rise of crest above the base line
Term
Electron Transport
Definition
Process by which a carrier molecule transfers electrons
Term
NADP+
Definition
nicotinamide adenine dinucleotide phosphate
carrier molecule
Term
ATP
Definition
adenosine triphosphate
5 carbon sugar ribose, 3 phosphate groups, adenine
Term
ADP
Definition
adenine diphosphate
adenine, 5 carbon sugar, 2 phosphate groups
Term
Light Dependent Reaction
(Hills Reaction)
Definition
requires light
produces oxygen gas
converts ADP and NADP+ into ATP and NADPH
Term
Photosystem II
Definition
light dependent
photolysis
pigment 680
2 electrons produced- hydrogen pumped, oxygen given off
Term
PS I
Definition
light depended
pigment 700
photophosphorylation
NADPH and ATP made
Term
Photolysis
Definition
when a water splitting enzyme splits the H20
Term
Plastoquinone
Definition
primary electron acceptor
passes electron to the protein pump b6- f complex
Term
b6-f complex
Definition
pumps protons from stroma to thylakoid- generates a protein gradient
Term
Photophosphorlyation
Definition
ADP is passed through ATP Synthase and phosphorylated by adding a phosphate group into ATP which is released into stroma
Term
Ferredoxin
Definition
transfers excited electron
Term
NADP Reductase
Definition
transfers electron to NADP- NADPH by adding a hydrogen
Term
Plastocyanin
pC
Definition
carries electrons to photosystem I from b6-f
Term
Light Independent Reactions
Calvin-Benson Cycle
Definition
uses ATP and NADPH to produce high-energy sugars
takes place in stroma
does not require light
carbon dioxide is converted in carbohydrates
Term
RuBisCO
RuBP
Definition
5 carbon molecule
C02 is added to it- splits into 6- then 3 carbon molecules
Term
3-phosphoglycerates
Definition
the 3 carbon molecules made after CO2 is added to the RuBP
Term
Gylceraldehyde-3-Phosphate
Definition
2 molecules produced after ATP and NADPH are added
