Exam 27: Seedless Plants

If a plant produces microspores and megaspores, then by definition, it is homosporous.

After a moss spore germinates, it forms a prothallus.

Mosses have stems, roots, and leaves.

Which plant has a jointed hollow stem with reduced megaphylls?

Prepare a table that lists the features that distinguish bryophytes from green algae and seedless plants.

Microphylls evolved from stem branches.

_____________ is the evolutionary process in which the spaces between close branches become filled with chlorophyll-containing cells.

Why are mosses and liverworts limited in size?

The oldest known mega fossils of _______________, discovered in New York, are dated at 380 million years old. These trees, which were about 8 m tall, had vascular tissues but no leaves and a minimal root system.

When two gametes fuse, the diploid portion of the life cycle is called ________________________.

How do mosses help prevent soil erosion?

Which group of plants were the most recent to evolve?

Discuss adaptations for terrestrial life seen in land plants.

The organic material compresses to form ___________.

An archegoniophore is found in certain liverworts.

The oldest known megafossils of early vascular plants may be characterized as:

_________________ are divided into three distinct phyla: mosses, liverworts, and hornworts.
