Document Summary
Bio 1140 a introduction to cell biology. Plant cell walls and plasmodesmata 3. Test your understanding 3. Animal cells: cell- cell connections 4: gap junctions 4, tight junctions 4, adhesive (anchoring) junctions 5. The extracellular matrix (ecm) of animal cells 6. Consolidate your knowledge 8. 1 | p a g e. For greater depth, read selectively from the following articles: Cell walls and the extracellular matrix . 2 | p a g e. Plant cell walls and plasmodesmata. Provides rigidity and protection, regulates permeability: hydrating matrix with reinforcing fibers cellulose microfibril. Cellulose is unusual because cellulose is synthesized on the outside of the cell. Patterns of cellulose microfibrils are determined by mts which determine where synthases can move. Lined with plasma membrane: route for ions, small molecules. Cell wall makes it difficult for cells to communicate with each other. 3 | p a g e. Rizwan awan: a variety of types, gap junctions, tight junctions.
