Heterospory is the term used to describe

Which of the following is a defining difference between the Gymnosperms and the Angiosperms?

A feature unique to Angiosperms is

Which of these sets of structures in mosses is wholly haploid?

Unlike their green algal relatives, the land plants

Which of the following features shared by Coleochaete and land plants is NOT found in Chara?

Molecular data suggests that ferns evolved in how many separate clades?

A diploid sporophyte produces haploid gametophytes from germinating spores. These spores must be produced by

In aquatic environments, nutrients are readily available to cells in the thallus by simple diffusion from the surrounding water. Thus a holdfast simply anchors algae to hard substrata. On land, however, plants require nutrients and water from the soil and the substratum is relatively soft and unstable. The evolution of roots rather than rhizoids represented a significant step forward in colonising and exploiting terrestrial habitats. The most primitive plants with roots are the

In Angiosperms, as ovules develop into seeds, the carpel becomes the

While on a field trip, a student in a moist, temperate gully discovers a small, haploid Filicophyte. The next stage of the life cycle will be a

Bryophytes are

Why are bryophytes confined to moist environments?

In seed plants, the megaspore is

Which statement is true about reproduction in the Bryophyta?

Elaters are

Which of the following statements about ferns is INCORRECT?

Which group of plants does NOT produce seeds?

An important role played by some mosses in dry Australian environments is to

In bryophytes, the diploid sporophyte is dependent upon the dominant gametophyte. As such, what must the ploidy of the rhizoids be?
