Tonicidade nas Plantas
Plant cells maintain appropriate osmotic balance in extreme conditions. For instance, plants in dry environments store water in vacuoles, limit the ...
Celulose e Polissacarídeos Pécticos
Every plant cell has a cell wall that protects the cell, provides structural support, and gives the cell shape. Cellulose, the main structural ...
Papel das Microtúbulos na Deposição da Parede Celular
Microtubules are small hollow tubes in eukaryotic cells. The cell wall microtubules are polymerized dimers of two globular proteins, α-tubulin and ...
Plasmodesmos
In a multicellular organism, cells must communicate to work together in a coordinated manner. One way that cells communicate is through direct contact ...
Adesão de Células nas Plantas
Plants have rigid cell walls that are made up of cell wall polysaccharides that mediate cell-cell adhesion. The primary cell walls of plants consist of ...
