The relationship between
Introduction:
For mosses, liverworts, and hornworts together, the term bryophyte is used. Because they are non-vascular plants, they lack roots or vascular tissue and instead take nutrients and water from the air via their surface.

Give one significant difference between sporophte and gametophyte.
Byrophytes are usually found in areas that are very wet or damp at least part of the year. Which of the following statements describes characteristics of byrophytes that make them dependent on water? State all that numbers that apply.
1. They have a dominant gametophyte phase.
2. They have swimming sperm that need water so they can swim to fertilize the eggs of other nearby plants.
3. They do not have lignin-stiffened vascular tissue or roots to effectively distribute water throughout the plant.
The gametophyte of Pteridophytes is inconspicuous in comparison to the mosses. They
are also commonly monecious (single house for male and female gamete production). The
photo below shows a whole mount (w.m.) of a fern gametophyte at 4x.
Make a sketch of the specimen and label the following structures: archegonium,
antheridium, mature gametophyte (prothallus), rhizoids
