Question

Differentiate between prosenchyma and pseudo-parenchyma.

Answer 1

Both prosenchyma and pseudo-parenchyma are modifications of hyphal structures. In prosenchyma, the component hyphae lie more or less parallel to one-another and unite to form a rather loosely interwoven structure where individuality of hyphae is not lost.

On the other hand, in pseudoparenchyma, the hyphae become closely interwined and loose their individuality. The hyphae are not distinguishable from each other and they appear like the parenchymatous tissue of higher plants in cross-section.
