Plants reproducing by spores such as mosses and ferns are grouped under the general term

  1. cryptogams
  2. bryophytes
  3. sporophytes
  4. thallophytes.

Answer

(1) cryptogams

Solution

Plants that do not produce flowers and seeds but reproduce by spores (thallophytes, bryophytes and pteridophytes) are called cryptogams ('hidden reproduction').

∵ Mosses are bryophytes and ferns are pteridophytes ⇒ both are cryptogams.

∴ The general term is cryptogams.
