Biology A small fibril in the cytoplasm or wall of a cell, visible only under an electron microscope, and typically aggregated into coarser fibrils or structures.
Example sentencesExamples
- According to current models of primary cell walls, cellulose microfibrils, which are the major tensile elements of the wall, interact with matrix components such as hemicelluloses, forming a complex network.
- Cellulose microfibrils within the guard cell wall are considered radial if they are oriented in the same way as the dotted lines (converging at the centre of the pore).
- In plant primary cell walls, cellulose microfibrils are coated with and cross-linked together with hemicellulose and the spaces in these networks are filled with pectins, which also form a network.
- Fibres distal to the vascular elements as well as the parenchyma cells in the ground tissue had weakly birefringent cell walls, which may be attributed to a transverse orientation of cellulose microfibrils in the primary cell wall.
- It was reported for pea that GA changes the orientation of microtubules and cellulose microfibrils, making the cells swell more in length.
