Question

In Pteridophytes, phloem contains

• A. Sieve cells
• B. Sieve tubes
• C. Companion cells
• D. Bast fibres

Answer 1

The correct option is A Sieve cells

Pteridophytes are called as seedless vascular cryptogams as they represent the first group of land plants with vasculature - xylem and phloem. The plant body is sporophytic and differentiated into true roots, stem and leaves. Pteridophytes are commonly called as the botanical snakes as they evolved after bryophytes (the amphibians of the plant kingdom). In phloem of angiosperms, companion cells and sieve tubes are present. In phloem of pteridophytes, sieve cells are present, companion cells and sieve tube are absent. Bast fibers are present in angiosperms only.

Hence the correct option is A.
