Parenchyma Cells in Plants: Structure, Classification and Functions (PPT)


functions of parenchyma

Parenchyma
(Structure, Classification and Function of Parenchyma)

What is simple tissue?

Ø  The tissue (a group of cells with particular function) composed of single type of cells.

Ø  Three types of simple tissue system in plants:

(1).  Parenchyma

(2).  Collenchyma

(3).  Sclerenchyma

What are the characteristics of Parenchyma (Parenchymatous Cells)?

Ø  Parenchyma is a simple permanent tissue.

Ø  They are living cells which contains plenty of water.

Ø  Cells are nucleated with prominent nucleus.

Ø  They are thin walled cells.

Ø  Cell wall composed of cellulosic primary cell wall only.

Ø  No lignin deposition in the cell wall of parenchyma.

Ø  Parenchymatous cells are relatively undifferentiated

Ø  Parenchyma is the least specialized along simple permanent tissues in plants.

Difference between Parenchyma and Collenchyma: A Comparison Table


collenchyma vs parenchyma

Parenchyma vs Collenchyma
(Similarities and Differences between Parenchyma and Collenchyma)

Parenchyma and Collenchyma are the Simple tissue System in Plants. The present post describes the similarities and differences between PARENCHYMA and COLLENCHYMA.

Similarities between Parenchyma and Collenchyma

Ø  Both parenchyma and collenchyma are simple permanent tissues in the plants.

Ø  Both are differentiated cells.

Ø  Both are living cells with primary cell wall.

Ø  Both cells possess cytoplasm and cell organelles including the nucleus.

Ø  Both are the components of ground tissue system in plants.

Ø  Both cells can do photosynthesis if chloroplasts are present in them.

Ø  Both can store food materials as starch grains.

Ø  Pits are absent in the cell wall of both parenchyma and collenchyma.

Ø  Plasmodesmatal connections between cells occur in both cells.
