Photosynthesis

Water potential

________: a measurement that combines the effects of solute concentration and pressure.

RUBISCO

________- is the enzyme that "fixes "carbon, it is the most abundant protein on earth.

PSI

________- gives the electrons to NADPH to carry into the Calvin cycle.

Phloem transportation

________ can be as fast as 1 meter /hour.

Photosynthesis

________ uses sunlight and CO2 to produce sugar and O2.

PSII

________- takes in light (photon), excites the electrons, and splits water into protons and O.

Sucrose

________ can be converted to starch after it has been unloaded into the sink.

ATP

At a source, sucrose is actively (requires ________ made by companion cells) loaded into sieve tubes.

mesophyll

Transportation- Cohesion theory: water loss by evaporation from ________ cells is replaced by water from the nearest xylem, water molecules "stick "together (cohesion), and form an unbroken column of water in vertical fills xylem vessels.

Carbon

Everything except ________, Hydrogen, and Oxygen comes from the soil and is transported by the xylem.

solute concentration

Increased ________ causes water to enter the sieve tube (via osmosis) at the source.

Calvin cycle

The ________ takes place in the stroma.

CO2

The ________ comes from the stoma (gas exchange) whereas the ATP and NADPH are made in the light reactions.

Apoptastic transport

________- around the cells, through the walls.

amount of photosynthesis, how the products are moved/stored,

What determines the yield of the plant?

Light reactions

________ take place in the thylakoid membranes of the chloroplast.

Symplastic transport

________- through the cytoplasm.

PSII

Electrons from ________ are transferred to the ETC which gives the protons to ATP synthase to make ATP.

Phloem Transport

________: dissolved sugars (mainly sucrose) are moved from "source "to "sink ..

Water potential

a measurement that combines the effects of solute concentration and pressure

Macroelements

Carbon, Hydrogen, Oxygen, Nitrogen, Potassium, Calcium, Magnesium, Sulfur, Phosphorus,

Microelements

Chlorine, Iron, Manganese, Zinc, Boron, Copper, Molybdenum, Nickel, Sodium

Symplastic transport

through the cytoplasm

Apoptastic transport

around the cells, through the walls

Transportation-Cohesion theory

water loss by evaporation from mesophyll cells is replaced by water from the nearest xylem, water molecules "stick" together (cohesion), and form an unbroken column of water in vertical fills xylem vessels

Phloem Transport

dissolved sugars (mainly sucrose) are moved from "source" to "sink."

Only 2 plants have the ability to store sucrose

sugar cane and sugar beet

About everything a plant does requires xylem and phloem

- photosynthesis, growth, development, responding to the environment, protection from pathogens and predators

Photosystems

PSII (P700) and PSI (680)

Light reactions

PSII

takes in light (photon), excites the electrons, and splits water into protons and O

PSI

gives the electrons to NADPH to carry into the Calvin cycle

RUBISCO

is the enzyme that "fixes" carbon, it is the most abundant protein on earth

Dark reactions
