The environments in which ferns grow range from standing water to very dry areas. Nonetheless, all ferns are dependent upon free water in order to complete their life cycles. Explain why is the case.

http://botit.botany.wisc.edu/botany_130/diversity/plants/mosses.html    Make a complete moss life cycle with the following phases and structures. Note:  download the images of Mnium from this link and arrange them in the exact sequence to make the lifecycle. Lifecycle structures with cell division: Meiosis, fertilization within archegonium, capsule (sporangium), spores (n), protonema (n) (Image), male gametophyte (n) (Image), female gametophyte (n) (Image), antheridia (Image), archegonia (Image), sperm, egg, water, zygote (2n), embryo, young growing sporophyte (2n), mature sporophyte (2n) (Image), rhizoids. You can insert the non-image part, using the textbox and fill out the suitable s text. For symbol, click on the shape option and inter in your lifecycle diagram at the required place

The gametophyte of Pteridophytes is inconspicuous in comparison to the mosses. They are also commonly monecious (single "house", or thallus for male and female gamete production). The photo below shows a whole mount (w.m.) of a fern gametophyte at 40x. Make a sketch of the specimen and label the following structures: archegonium, antheridium, mature gametophyte (a.k.a. prothallus), rhizoids 90

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.
