What is the difference between sclerenchyma and parenchyma tissues?
Answers
Explanation:
Parenchyma have little space between them
Sclarenchyma have no space between them
Parenchyma are living cells
Sclarenchyma are dead cells
Answer:
Parenchyma cells are the type of living plant cells, which are known for healing and repair mechanism, and food storage.
Parenchyma is the most simple tissues made up of living cells and forming the thin layer called as primary cell wall of the plant. Parenchyma is taken from the Greek word “Parenchyma”, meaning ‘something poured in beside’. In plants, parenchyma cells are widely distributed all over and occur as continuous mass from the stems to roots, leaves, fruits.
Sclerenchyma cells are the matured dead cells and are found in wooden part or hard stem of the plant.
Sclerenchyma is said as the dead tissues of the plants because it comprises of the hardwood. The secondary walls of the matured sclerenchyma cells are densely thick and contain lignin and hemicellulose. These types of cells are hard, non-growing and non-stretchable and are present in mature stems or bark. Sclerenchyma is found in many different sizes and shapes, but sclereids and fibres are of main types. Sclereids are found in tissues like xylem, phloem, pith, cortex and periderm. This cell also contributes to the hard covering of nuts and fruits and other seeds too.
