Answer:

Two peculiar characteristics of porella thallus are the dorsoventral stem which is bipinnately or tripinnately branched, and large-unequal bilobed dorsal leaves and a single row of ventral leaves.

Explanation:

Porella is a large and common liverwort spread worldwide. This plant does not contain a true stem, true leaves, or roots. Therefore they are referred to as thallus. Two peculiar characteristics of porella thallus include: -

  • It consists of a slender dorsoventral and an extensively branched stem. The branches are either bipinnate or tripinnate.
  • Large dorsal leaves are present with only a single row of ventral leaves. The dorsal leaves are present with two unequal lobes (bilobed).
