Question

What is circinate ptyxis and furcate venation in fern?

Answer 1

Fern:

A fern is a vascular plant that reproduces by spores instead of seeds or flowers.

Circinate ptyxis and furcate venation:

1. In fern fiddleheads, circinate vernation is a coiled arrangement of fronds (leaves).
2. Circinate ptyxis is a distinguishing feature of ferns in which the leaf folds during the developmental stages.
3. Furcate venation refers to veins that divide and produce a fork, but the branches do not join.
