The cyclic differs from the non-cyclic light reaction in that

• electrons return to the chlorophyll molecule in the cyclic reaction.

• only higher plants are capable of doing the cyclic reaction whereas all photosynthetic organisms use the non-cyclic reaction.

• whereas NADPH is produced in both, more of it is manufactured in the non-cyclic reaction.

• whereas ATP is produced in the cyclic reaction, none is produced in the non-cyclic reaction.

If a root cell is hypertonic compared to the soil surrounding it

• water will move out of the root cell and into the soil

• water will move into the root cell out of the soil

• minerals will leave the root cell and move into the soil

• minerals will be drawn into the root cell from the soil

If a root cell is hypertonic compared to the soil surrounding it

• water will move out of the root cell and into the soil.

• water will move into the root cell and out of the soil.

• minerals will leave the root cell and go into the soil.

• minerals will be drawn into the root cell from the soil.

Light energy is actually converted to chemical energy as a result of

• photons being converted first to inorganic cations and then to organic molecules.

• chlorophyll electrons being energized by light and then passed on to various molecules such as NADP.

• light energy being trapped directly by glucose molecules.

• water molecules being broken down as light hits them.

Phloem sap moves nutrients toward the root once

• potassium ions are transported out of phloem sieve tube cells.

• sucrose is actually transported into phloem sieve tube cells.

• water is transported out of phloem cells and into xylem cells.

• hydrogen ions are pumped out of phloem sieve tube cells.

Along with plants, which of the following organisms are capable of photosynthesis?

• fungi & bacteria

• cyanobacteria & algae

One would predict that xanthophylls use less light from which portion of the visible spectrum?

• green

• blue

• yellow

• red

• orange

Anions are absorbed into root cells when they

• are attracted to the positive cytosol.

• follow hydrogen ions into the cell.

• are repelled by clay particles in the soil.

• follow cations such as potassium and sodium into the cell.
