phylotaxy

Back 27

arrangement of leaves on stem

Front 28

____ intake and restriction of _____ ____ are vital to phyllotaxy.

Front 29

what is a vascular plant?

Back 29

Vascularplantshavevascular tissues which distribute resources through the plant. Vascular transport allows for larger plants. Vascular plants include trees, flowers,grasses and vines. Vascular plants have a root system, ashoot system and a vascular system. Roots are simple tissues that are derivedfrom the stem of the plant. Roots anchor the plant in the ground and transportminerals and water into the plant.

Front 30

what are xylem and phloem

Back 30

vascular tissue that transport fluid and nutrients internally. The xylem isrigid tissue that transports water throughout the plant. Xylem tissuecan be found throughout the plant, in the roots, stem and leaves. The phloemtransports photosynthetic products from where they are made to where they arestored. Phloem bring minerals upthrough the roots and the byproducts of photosynthesis down tomove them throughout the plant.

Front 31

what is turgor pressure

Back 31

maintains stiffness of plant tissue

Front 32

osmosis

Back 32

Water moves from regions of higherconcentration to regions of lower concentrations.MPa is a unit of pressure with which wemeasure water potential. Mpa ofpure water in an open container at sea level and room temp is0.

Front 33

water potential

Back 33

Water potential is the measure of potential energy in water and drives the movement of water throughplants. solutes and pressure affect water ptential

Front 34

water potential equation

Back 34

water potential = solute potential + pressure potential

Front 35

aquaporins

Back 35

transport proteins that facilitate the movement of water molecules across plant plasma membranes

Front 36

bulk flow

Back 36

movement of liquid in response to pressure gradients, is independent of solute concentrations

Front 37

______ drives the transport of water and minerals from roots to shoots via the ____.
