Cell Wall Types

What is cell wall?

Read the passage and answer the questions that follow: Simple tissues are also known as ground tissues. They include the tissues known as parenchyma, collenchyma, and sclerenchyma. The parenchyma tissue is composed of parenchyma cells, which are found throughout the plant. They are particularly abundant in the stems and roots. The leaf cells that carry out photosynthesis are also parenchyma cells. Unlike many other plant cells, parenchyma cells are alive at maturity and retain the ability to divide. They perform many functions. Some are special ised for photosynthesis, some for storage, and oth ers for secretion and transport. Like parenchyma cells, collenchyma cells are alive at maturity. They differ from parenchyma cells in that they have thick cell walls. The col lenchyma tissue is most often found in the form of strands or cylinders of cells in stems and leaves. The thick cell walls of collenchyma cells provide support to these plant structures. The strands of tissues in celery are collenchyma tissues. Even collenchyma cells retain the ability to divide. Sclerenchyma consists of thick-walled dead cells. It possesses extremely thick secondary walls due to uniform deposition of lignin. It provides mechanical strength. The cells may occur singly or in groups and may be long and fibrous or stony.Stone cells (sclereids) are found in seed coats and some fruits (e.g, pear). What type of tissue accounts for the crunch when you eat celery?
