Cytoskeleton – structure Network of fibers extended throughout the cytoplasm FLEXIBLE! Cytoskeleton function Mechanical support Maintain shape (animal cells) Anchors organelles in addition to molecules Motility Moves entire cells Moves part of the cell Motor proteins needed (whole cell, cilia, flagella, muscle contraction, vesicle movement) Signal transduction Cytoskeleton components

Microtubules – Centrioles 9 sets of 3 Microtubules – Cilia in addition to Flagella Microtubules – Cilia in addition to Flagella

Microfilaments Plant cell wall Cell protection, shape maintenance, prevents water uptake Found in some prokaryotes, protists, in addition to fungi Cellulose + other polysaccharides Extracellular Matrix

Carbohydrate functions Intercellular junctions Cell membrane structure

Protein functions Membrane permeability Is the cell membrane permeable to Hydrophobic (nonpolar) molecules Ions Polar molecules Small versus large molecules Aquaporins Lab 1: Diffusion & Osmosis Concepts semi-permeable membrane diffusion osmosis solutions hypotonic hypertonic isotonic water potential

Diffusion vs. osmosis Lab 1: Diffusion & Osmosis Tonicity

Water potential (KNOW THIS WELL!) : Water potential (in MPa) Always higher to lower s : solute potential (osmotic potential) Always (-) p : Pressure potential (+ or -) Animal cells: = s ( Plant cells: = s + p Facilitated diffusion
