  • This also means more water and nutrients can be easily transported throughout the plant to promote faster and healthier growth. (growdaddycanada.com)
  • Biologists have been interested in this fact for centuries and theories on how plants are able to follow this pattern of growth have been proposed by the likes of Leonardo Da Vinci, amongst others. (basicbiology.net)
  • Primary cell wall expands by acid growth mechanism. (biologyonline.com)
  • By acid growth mechanism, the primary cell wall may also function by increasing the extensibility of the cell wall. (biologyonline.com)

  • 2 ]. (B) Continuous polarized growth or isotropic growth from a lobed initial cell can lead to the typical pavement cell shape. (biomedcentral.com)
  • While the pavement cells obviously have all the features associated with the diffuse growth mode, it has been proposed that the lobe domains of these cells behave like tip-growing regions, notably by expanding at a greater rate than the rest of the cell (Figure 2b ). (biomedcentral.com)
  • Macrophomina phaseolina is one of the most destructive necrotrophic fungal pathogens that infect more than 500 plant species throughout the world. (biomedcentral.com)
  • As the plant uses silica to build up cells, it becomes harder for pathogens such as rust and powdery mildew to enter and damage the plant. (growdaddycanada.com)
