luxury consumption of a nutrient is - is not harmful to the plant. the plant just takes up a lot of the
nutrients.
Diffusion is - The way nutrients move from areas of high concentration to areas of low concentration
Active transport - Is regulated because energy and a protein carrier are needed to move and ion across
the membrane
The Casparian strip - A narrow, thickened band of water-proofed material around the endodermal cells
that regulates nutrient uptake
The light dependent reaction of photosynthesis - ATP is produced by ATP synthase and oxygen is
released
Rubisco can fix both CO2 and O2. - True. because of this, plants are less efficient in producing sugars
Which steps is the beginning of photosynthesis? - Pigments in PS (photosystem) II absorb light
The Hill reaction takes place in - All of the above
Under water stress conditions, ____ is produced which increased ____ concentrations in the guard cells,
causing the ____ to _____. - Abscisic acid (ABA); K+ ion; stoma; close
The amount of a plant available nutrient in the soil is influenced by - All of the above
Which answer below correctly identifies a macro essential element and its main function/purpose in a
plant? - Magnesium - chlorophyll
Nutrients in the plant move thru the: - All of the above
, Chlorophyll a absorbs energy at ___ nm, while chlorophyll b absorbs energy at ___ nm, and carotenoids
absorb energy at ___ nm - 675; 640; 400-500
Photorespiration often occurs when - a and b
what is the name of the biological process that converts ADP to ATP (energy) by adding an additional
phosphate during the Hill reaction? - Photophosphorylation
For non-cyclic photophosphorylation, photosystem I happens ____ photosystem II. - after
chemiosmosis - Diffusion across a thylakoid membrane from an area of high proton concentration to an
area of low potion concentration, creating ATP
Which of the following statements is true? - Photosynthesis is limited by light in a C4 plant and by CO2 in
a C3 plant
Leaf area index or LAI - is the measure of the leaf surface area with a particular area of soil.
how does the water supply in the soil influence photosynthesis? - Yes. if the water supply in the soil is
high, then the plants can take up water easily, allowing the stomates to be open for gas exchange.
Photolysis is - the splitting of water using energy from the sun, at PS II, on the lumen side of the
thylakoid membranes
which statement below is accurate about the three stages of the Calvin cycle in a C3 plant? - In the third
stage RuBP is regenerated from the GA3P compounds; this stage requires energy
The O2 that is released during the photosynthesis - Came from H2O during photolysis that occurred in
the lumen of the thylakoid membranes
