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

e th aci st SJ I the size, shape, and arrangement of the leaves, which are microphylls, small leaves with only one vein. Examine the roots and their relationship to the stem. In Selaginella, the roots grow downward from a leaf-bearing stem. The sporangia of the Lycopodiophyta are borne on leaves essentially similar to the sterile leaves of the plant. The sporangium bearing leaf is called a sporophyll. In Selaginella and Lycopodium, the sporophylls occur in compact aggregates called cones, or strobili. 1. Label the microphylls and strobili in the Figure 1 below. Figure 1. Lycopodium sp. Examine the prepared slide of a mature Lycopodium strobilus. (See text Figure 17-16, pages 406 and 407.)

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.
READ THE FOLLOWING INSTRUCTIONS: Bryophytes in which the gametophytes are "leafy" in appearance and the sporophytes grow conspicuously from the tips of the gametophyte plants. STEP 1: Examine the mass of moss plants and then select one or two individual gametophyte plants and note the leaf-like (not true leaves because they lack conducting tissue) structures which are arranged around a central, vertical "stem-like" stalk and root-like rhizoids which anchor the plant and absorb water and nutrients. STEP: The sex organs are in the tips of the plants and must be seen with the microscope. Study a slide of a vertical section through head of a mate plant and note the many antheridia. STEP 3: Examine a slide through a vertical section of a female plant. Note the many upright archegonia each on a tall stalk and each with a swollen base or venter containing an egg and an elongate neck. Note the filamentous paraphyses between the archegonia. STEP 4: Examine a living or preserved…
