TONOPLAST: CHARACTERISTICS AND FUNCTIONS
Tonoplast has a selective permeability and locks up water, ions, and solutes within the vacuoles. There are exhaustive studies on the molecular composition of the tonoplasts, since the transporter proteins located in these membranes regulate plant growth, stress to …

Increase in the permeability of tonoplast of garlic …
Increase in the permeability of tonoplast of garlic (Allium sativum) by monocarboxylic acids. J Agric Food Chem. 2006; 54(21):8103-7 (ISSN: 0021-8561) Bai B; Li L; Hu X; Wang Z; Zhao G
Meloidogyne incognita-Induced Changes in Cell …
permeability of the tonoplast and the plasma membrane of cells in nongalled roots is increased by nematode infection on the other half of the root system. Thus, a mechanism for mobilizing minerals to the infection site is proposed. Key Words: root-knot
Modulation of proton pumping across proteoliposome …
SG and ASG also reduced the passive proton permeability of the proteoliposomes. These results show that SG and ASG modulate proton pumping across the tonoplast toward stimulation and depression, respectively, and they reduce the passive proton permeability of the tonoplast.
Effects of NaCl stress on plasmalemma and tonoplast …
Lycium barbarum growing in Ningxia was employed to study the relation of salt tolerance with water content,dry matter weight,inorganic ion distribution, plasmalemma permeability and MDA content in L. barbarum seedlings and plasmlemma and tonoplast H
What Factors Affect the Permeability of a Cell Membrane?
· The permeability of a cell membrane is affected by the polarity, electric charge and molar mass of the molecules that diffuse through it. A cell membrane consists of two phosolipid layers. Each layer has an electrically charged and hydrophilic head, while the tail is

Factors Affecting Membrane Permeability Lab Activity Key Idea: high temperatures can disrupt the structure of cellular membranes and alter their permeability making them leaky. Membrane permeability can be disruptive if membranes are subjected to high temperatures. At temperatures above the optimum, the membrane proteins become denatured (they lose their shape). The denatured proteins no
Effect of Detergent Concentration on Membrane …
· Aim: To investigate how effect of Detergent Concentration (cont.) has on Membrane permeability of Beetroot cells. Hypothesis: I predict that as detergent concentration increases, the solution will become less clear, plus mass increases. The …
The Effect Of Temperature On a Cell Membrane’s …
The effect of temperature on the permeability of cell membranes Introduction For my coursework, I intend to assess how temperature affects the plasma membrane of a cell.For this I will use the cell of a beetroot. Background What is a cell membrane? The cell membrane, also called the plasma membrane is a semipermeable lipid bilayer which is the surface of all cells that surrounds the cytoplasm.
