A) Independent sporophyte

B) An independent gametophyte

C) Swimming antherozoids

D) Dominant sporophytic phase

Answer:

Pteris differs from funaria in having independent sporophyte.

Explanation:

• Pteris is a fern and funaria comes under mosses.
• If we see the life cycle of a fern, there is sporophytic and gametophytic stage and sporophytic stage is independent of gametophytic phase.
• On the other hand, in funaria, life cycle is haplo-diplontic and gametophyte is a leafy stage which dominates over sporophytic stage.
• Plant body of funaria has two forms – one, gametophyte which is free living and the second, leafy gametophore. Leafy gametophyte is the dominant stage in funaria.

Hence, Pteris has an independent sporophyte, whereas funaria has dependent sporophytic stage.
