Question

Difference between parenchyma collenchyma and sclerenchyma

Answer 1

Parenchymal:

1):The cells of parenchyma are soft,thin walled and loosely packed.

2):They store food,bears chloroplasts and contain larger cavities.

Collenchyma:

1):The cells of collenchyma are thick walled and compactly arranged.

2): They give mechanical strength in young tissue of stem.

Answer 2

Parenchyma: Parenchyma cells are found in every soft part of the plant like leaves, fruits, bark, flowers, pulp and pith of the stems.

Collenchyma: Collenchyma cells are found in petiole, leaves and young stems, appearing as a continuous ring beneath the epidermis.

Sclerenchyma: Sclerenchyma is found in the mature parts of the plant like herbaceous perennials and woody plants.

Specialized/Unspecialized

Parenchyma: Parenchyma cells are unspecialized cells.

Collenchyma: Collenchyma cells are specialized cells.

Sclerenchyma: Sclerenchyma cells are specialized cells.
