1. What are the functions of sclerenchyma?
The cells are found in many places throughout plant bodies and, given that they are alive, are actively involved in photosynthesis , secretion , food storage, and other activities of plant life.
Structure of sclerenchyma: The sclerenchyma cells show the following characteristics: (1) The cells are heavily thickened with lignified walls, simple pits and small lumen. 3.
Two views of the structure of the root and root meristem. Vascular tissue includes xylem, phloem, parenchyma, and cambium cells. Parenchyma cells are notable for their thin walls, and for being alive at maturity. It is one of the three ground tissues in plants and is involved in photosynthesis, food storage, and secretion. Simple tissues are composed of a similar group of cells and responsible for carrying out a certain set of functions in the plant body. Plant tissues can be divided to 5 main types as Parenchyma, Xylem, Phloem and 2 others. Likewise the humans, who have bones to support their body structure, plants also have certain specialized tissues which help them, by providing support to their structure, protecting the inner parts, giving strength, etc. Complex permanent tissue is composed of two or more than two types of cells and contribute to a common function.
In this video, Dr. Shanty Paul explains the simple permanent tissues (parenchyma, collenchyma and sclerenchyma) in detail, using simple animations. This … Mature sclerenchyma cells are usually dead and have thick secondary cell walls.

Provides hardness to stony fruits such as nuts, coconut, almond etc; 2. ... Sclerenchyma Tissues.
Parenchyma, collenchyma, and sclerenchyma cells are common in the ground tissue. Parenchyma, in plants, tissue typically composed of living cells that are thin-walled, unspecialized in structure, and therefore adaptable, with differentiation, to various functions. A sclerenchyma tissue shows the following characteristic features. Collenchyma cells tend to develop thicker secondary cell walls, to support structure.
Sclerenchyma is a simple tissue while xylem is a complex tissue.
The key difference between collenchyma and sclerenchyma is that collenchyma is a type of live plant cell that has irregularly thickened primary cell walls while sclerenchyma is a type of dead plant cell that has heavily thickened secondary walls..
Sclerenchyma offers only mechanical support while xylem is mechanical and it also helps in conduction. Parenchyma tissue is found in the inner layers of leaves, in fruits and seeds, and in the cortex and pith of roots and stems.
