Define Parenchyma and Sclerenchyma
Answers
Explanation:
It can be divided into three types based on the nature of the cell walls. Parenchyma cells have thin primary walls and usually remain alive after they become mature. ... Sclerenchyma cells have thick lignified secondary walls and often die when mature. Sclerenchyma provides the main structural support to a plant.
Parenchyma is a term used to describe the functional tissues in plants and animals. This tissue is “functional” – performing tasks such as photosynthesis in plants or storing information in the human brain – as opposed to “structural” tissues like wood in plants or bone in animals.
Sclerenchyma tissue, when mature, is composed of dead cells that have heavily thickened walls containing lignin and a high cellulose content (60%–80%), and serves the function of providing structural support in plants. Sclerenchyma cells possess two types of cell walls: primary and secondary walls.
