Answer 1

Selaginella belongs to

Explanation:

Lycopodiophyta division

Answer 2

Answer:

Selaginella belongs to the division​ Lycophyta.  

Explanation:

Systematic Position of Selaginella-

Division​ Lycophyta

Sub-division: Lycopsida

Class: Ligulopsida

Order: Selaginellales

Family: Selaginellaceae

Genus: Selaginella

• Lycopsida (Lycopods) include primitive vascular plants which possess differentiation of roots, stems and leaves.

• Leaves are microphyllous, i.e., small and do not possess a leaf gap in a vascular strand of the stem.

• Sporophylls form sporangiferous spikes or strobila. Sporangia develop either axially or adaxially.

• Branching is dichotomous or pseudo dichotomous.

• Examples include Lycopodium and Selaginella.

Selaginella (Club Moss, Spike Moss)

• Selaginella represents a trailing, hanging or erect evergreen lycopod.
• The plant body is sporophytic.

• These resurrection plants turn green with the availability of water. e.g., S. bryopteris (Sanjivani booti) and S. lepidophylla.

• The stem has dichotomous branching in erect and hanging species.

• Leaves are simple, sessile and microphyllous.
• Each of the leaves On the basal adaxial surface leaves bears a small scale called ligule which is why they are often called ligulate leaves in Selaginella.

• Roots are adventitious and develop either directly from the stem or at the top of a special leaflet, positively geotropic structures called rhizophores.

• Rhizophores are peculiar to Selaginella. They arise from either base of the stem or the region of stem forkings.
