Sclerenchyma is the tissue which makes the plant hard and stiff. Sclerenchyma is the supporting tissue in plants. Two types of sclerenchyma cells exist: fibers cellular and sclereids. Their cell walls consist of cellulose, hemicellulose, and lignin. Sclerenchyma cells are the principal supporting cells in plant tissues that have ceased elongation.
They are typically 1 mm (0.039 in) in length and are thus named fiberlike sclereids. These sclereids permeate the mesophyll as a dense mat. [ 5 ] During sclerification these fiberlike sclereid cells can increase by several hundred times their original size, compared to other parenchyma cells that only increase by two or three times.
The pericycle is a cylinder of parenchyma or sclerenchyma cells that lies just inside the endodermis and is the outer most part of the stele of plants. [ citation needed ] Although it is composed of non-vascular parenchyma cells, it's still considered part of the vascular cylinder because it arises from the procambium as do the vascular tissues ...
Windows 3.1 is a major release of Microsoft Windows.It was released to manufacturing on April 6, 1992, as a successor to Windows 3.0.Like its predecessors, the Windows 3.1 series run as a shell on top of MS-DOS; it was the last Windows 16-bit operating environment as all future versions of Windows had moved to 32-bit.
[1] [2] Tissues occupy a biological organizational level between cells and a complete organ. Accordingly, organs are formed by the functional grouping together of multiple tissues. [3] The English word "tissue" derives from the French word "tissu", the past participle of the verb tisser, "to weave".

Phloem (/ ˈ f l oʊ. əm /, FLOH-əm) is the living tissue in vascular plants that transports the soluble organic compounds made during photosynthesis and known as photosynthates, in particular the sugar sucrose, [1] to the rest of the plant.
