This many years ago agriculture began in the Fertile Crescent. 

What is 13-11,000 years ago?

100

These three features distinguish plant cells from animal cells.

What is the cell walls, vacuoles, and chloroplasts?

100

Water potential is higher at the roots of the plant than the leaves due to this 'unavoidable evil'

What is transpiration?

100

The term that refers to liverworts, hornworts, and mosses that developed a cuticle but not yet a vascular system is this. 

What is Bryophytes?

100
This is the reason for counting growth rings on trees to estimate age. 

What is trees produces one xylem ring a year that reflects it's environment?

200

This term came about after Norman Borlaug combined dwarf, disease resistant plants with high amounts of fertilizers to try and feed masses.

What is the Green Revolution?
200

These plastids contain yellow and orange pigments that plants have in their petals or fruit to attract pollinators or dispersal agents.

What is chromoplasts?

200

Thanks to the cell wall for making sure the cell does not burst, this is the hydrostatic pressure in plant cells that is the result of osmosis or imbibition.

What is turgor pressure?

200

These are the three tissue systems in the plant body. 

What is Dermal tissue, ground tissue & vascular tissue?

200

This plant type has parallel veins in its leaves and a stem that has no pith or cortex, but instead a vascular bundles spread evenly throughout.

What is a monocot?

300

This institutionalized discrimination (1930-1970ish) by Home Owners' Loan Corporation (HOLC) based on race, religion, income, etc, is cited as one of the reasons there is a disparity in tree cover between high and low income neighborhoods. 

What is redlining?

300

These are the principal conducting cells in the xylem.

What are tracheid and vessel elements?

300

Phloem movement is osmotically driven, in what scenario would active transport take place in the companion cell?

What is, when solutes are unloading into a cell with a higher solute concentration level?

300

These are the three cell types the comprise the plants ground tissue and support tissue.

What is parenchyma, collenchyma, and sclerenchyma cells?

300

This is the non-conducting wood that is often the majority of wood in thick stems. 

What is heartwood?

400

The tendency for plants to fall to the background or go unnoticed is this. 

What is Plant Awareness Disparity or Plant Blindness?

400

These are the principle conducting cells in the phloem.

What is sieve cells, sieve-tube elements, and companion cells?

400

This is the theory that explains how osmosis moves solutes from the source to the sink in the plant. 

What is pressure-flow mechanism?
400

These 2 compounds are found cells of the phloem, are deposited on sieve pores when the plant is injured.

What is P-protein and callose?
400

This is the protective tissue during secondary growth, more informally termed the bark and produced by the cork cambium.

What is periderm?

500

Selection in plant attributes that genetically alter plant populations to make them more easily cultivated by humans. For example wheat, barley & flax

What is domestication?

500

This is the channel between protoplasts over which the modified endoplasmic reticulum traverses to transport signaling compounds.

What is the plasmodesma?

500

This is the theory that explains how water moves from a region of higher to lower water potential.

What is cohesion-tension theory?

500

This is responsible for producing secondary xylem and phloem. 

What is the vascular cambium?

500

Early wood with thinner cell walls and larger pores is likely developed by the plant in this season. 

What is the spring?
