Plant Structures/Functions Exam 2

Integral constituents of the thylakoid membrane associated with the photosynthetic apparatus, light absorbed is transferred to chlorophyll, considered accessory pigments

Measure of the potential of water to move from 1 cell to another as influenced by solute concentration

Rough percentage of wavelengths being absorbed

Uses products from earlier in Redox process to make ATP

Complex 2, Succinate is oxidized

When some incoming light is propagated through the central vacuoles of palisade cells and air space

Main element of stomatal mechanics

Moves electrons through the Redox cycle through plastoquinone from PS2, sends plastocyanin to PS1

Group of progenitor cells that give rise to leaf and bud primordia

The separation of cell layers that happens at the bases of leaves, flowers, and fruits which allows them to be dropped without harm to the plant

State of phloem cell walls

Found nearly exclusively in land plants, prevents Rubisco from being an oxygenase, accumulates CO2 from Malate

Most photosynthesis occurs in...

Made of light/pigment molecules, leads to reaction centers

Process by which energy is released and stored as ATP for short term plant growth and development

Source to sink model for auxin flow, hypothesizes that auxin flows through tissues it stimulates, polarizing its own transport which becomes channelized over time, forming files of cells leading away from the auxin source which differentiates into vascular tissue

Leaf is fully healthy and functional before any signals indicating otherwise, a gradient of auxin from the leaf blade to the stem maintains the abscission zone in an insensitive state

Shoot apical meristem stops differentiating, ends as a terminal organ or stopping of growth

Sugars converted to hexophosphates, which become phosphorylated and split, resulting in 2 trio phosphates

12 O2 + 49H+ + 48e- --> 24 H2O
