Question

1. Which of the following is NOT a possible outcome for water entering a plant?

used to fill up the cell

lost due to transpiration

accepts electrons from the ETC

donates electrons to the ETC

2. Light energy is transferred through the light harvesting complex as

photons

electrons

energy resonance

the antenna complex does not transfer energy

3. The Casparian Strip

stops water loss in leaves

controls uptake of nutrients

allows solutes to move freely into the root

is found only in desert-adapted plants

4.Thylakoid membranes are important for

organizing the components of the electron transport chain

allowing the creation of an electron gradient between the stroma and lumen

organizing the components of the Carbon reactions

all of the above

5.Standard photosynthesis is called "C3" photosynthesis because

there are three phases to the Calvin-Benson cycle

carboxylation and reduction occur three times before regeneration

the first stable molecule formed is a 3-carbon sugar

all of the above

6. Cactus and other plant adapted to very arid environments display

C2 photosynthesis

C3 photosynthesis

C4 photosynthesis

CAM photosynthesis

7.Which of the following most accurately describes phloem?

normal, living cells

empty tubes of dead cells

zombie cells that are alive, but lack a brain (nucleus)

8. Apoplastic phloem loading requires

a proton-sucrose antiporter

secondary active transport of sucrose

very high concentration of sucrose in the source cell

P-proteins

9. At the end of oxidative phosphorylation, electrons are given to water
oxygen
ATP

NAD+

10. NADP+ is reduced to NADPH during

the light reactions

photorespiration

the carbon reactions

oxidative phosphorylation
