Structural Characteristics of Developing Nitella Internodal Cell Walls
The Nilella intermodal cell is formed by a division of the segment cell, the latter being a direct derivative of the shoot apical cell. The internodal cell is remarkable in that it elongates from an initial length of about 20 microns to a mature length of about 60 millimeters. The structures of the apical and segment cells, and the internodal cells in all stages of development were examined wit...
متن کاملProtoplasmic Streaming of an Internodal Cell of Nitella Flexilis
The sudden cessation or sudden decrease in velocity of the protoplasmic streaming of Nitella flexilis is observed whenever an action potential is elicited. The action potential can be generated by an electric stimulus after its refractory period, whether the flow is at a complete standstill or on the way to recovery. The membrane potential is generally decreased more or less when the rate of fl...
متن کاملDiffusive Promotion by Velocity Gradient of Cytoplasmic Streaming (CPS) in Nitella Internodal Cells
Cytoplasmic streaming (CPS) is well known to assist the movement of nutrients, organelles and genetic material by transporting all of the cytoplasmic contents of a cell. CPS is generated by motility organelles that are driven by motor proteins near a membrane surface, where the CPS has been found to have a flat velocity profile in the flow field according to the sliding theory. There is a consi...
متن کاملRelease of Small Polyuronides from Nitella Cell Walls during Ionic Exchange.
Mono-divalent ion exchange in isolated cell walls of Nitella flexilis (L.) Ag. induces a marked loss of wall polymers and a decrease in the wall cationic exchange capacity. These data correlate with the replacement in the walls of adsorbed Mn(2+) by Na(+) ions. Boiling wall samples in methanol for 1 h or keeping the ionic solutions chilled to 4 degrees C does not inhibit the cell wall polymer l...
متن کاملCharacteristics of cell walls from morphological variants of Escherichia coli.
Two strains (E-26 and B) of Escherichia coli were examined for their growth response in a medium containing 0.75 yo (w/v) NaCl, 1 yo (w/v) L-lysine hydrochloride, 2 % (w/v) glucose, 2.4 % (w/v) nutrient broth, and 5 % (w/v) casein hydrolysate. Strain E-26 grew as a rod which was slightly larger than when it was grown in a defined medium. Strain B grew as a filamentous and branched form; while i...
