Summary Introduction
To review:
The chances of coexistence/occurrence of fossils of spike moss and related members of last common ancestor of seed plants and ferns in the same geological strata. In case, these plants do not exist in the same strata, give the name of strata (lower or higher than that of the spike moss) where the last common ancestor of seed plants and ferns would occur.
Introduction:
Spike mosses usually have a tropical distribution and mainly grow in moist-shaded habitats. A few spike mosses are found in deserts. Some of the species of a group of lycophytes called spike mosses are popular for cultivation. They are perennial, terrestrial or annual plants, which lack true roots. The spike mosses belong to a single genus, Selaginella.

Do mosses have an alteration of isomorphIC Or heteromorphic generations? That is, can youeasily tell a moss gametophyte from a moss sporophyte? When we look at leafy green mossplants, what are we seeing - gametophyte or the sporophyte? in a fiowering plant species,would the equivalent stage be the plant the pollen grains and megagametophytes
How might Bryophytes and Lycophytes (“true” mosses and spikemosses) have contributed to the evolution of flowering plants and other land plants?
What key traits distinguish each group from the other listed in the comparison?

B) Pteridophyta (ferns) from Bryophyta (mosses)?
C) Angiosperms from ferns?

In one feature, certain stems grow longer than others, and thus, rather than having dichotomous branching, they have branching (displayed especially by Pertica). Simultaneously, the positioning of branches became more and .arrow_forward
