Chapter 12:
Concepts
Ability to transport molecules against the direction they would have diffused in if alone
After death occurs, atoms, ions, and molecules diffuse, moving from regions of higher to lower concentration, and organization protoplasm decays; disorder increases
Diffusion is slower in controlled and oriented transport processes
Transport Processes- consume energy, and many are driven by the exergonic breaking of ATPs high-energy phosphate-bonding orbitals.
Short-Distance Transport: involves distances of a few cell diameters or less
Involve transfer of basic nutrients from cells with access to the nutrients to cells that need them
Became necessary to internal cell survival
Long-Distance Transport: between cells that are not close neighbors
Not essential in large plants
Ability to conduct over long distance is adaptive
Specific transport at every level of biological
Ex: Cells transport material in and out of themselves as well as circulate it within the protoplasm.
Ex: Entire organisms transport nutrients from one organ to another
