M. hdusia (singular: indusium) (See text Figure 17-32, page 420). by specialized outgrowths of the leaf 6. Is the indusium diploid or haploid?. Obtain a small square of a fern leaf with one associated sorus. Scrape the sorus off of the leaf and onto a dry slide. It is ok if the sporangia separate from each other. Examine the sporangia under the microscope's low power objective. As the sporangia dry, they will begin to discharge their spores. 7. Do the spores belong to the sporophytic or the gametophytic generation? 8. What type of nuclear division (within the sporangia) gives rise to the spores?

Exercise II Bryophyta: The Mosses Examine with the dissecting microscope the mosses that are available. The "leafy" plants are the gametophytes and any elongated structures growing above them are the sporophytes. (See text Figure 16-27, page 385.) 15. Label the following in Figure 5 below: spores, zygote, protonema, gametophyte, meiosis, female, male, sporophyte, archegonia, sperm, sporangium.

Moss Life Cycle (drawn by Stephanie Preising, SCSU '20) Obtain a gametophyte and observe its symmetry, its leaf like structures, its axis (pseudo- stem), and is rhizoids. Some species of mosses are unisexual; others are bisexual. The moss gametophyte originates as budlike structures that develop from a protonema (plural: protonemata), a system of branching filaments derived from a germinating spore.

Exercise 2: Construct an indented dichotomous key on the following groups of plants: Bryophyta Lower Vasuclar plants Higher Vascular plants Gymnosperms Angiosperms Pteridophyta Equisetophyta
TOPIC: SEEDLESS VASCULAR PLANTS IDENTIFICATION 1. The dominant stage in the life cycle of ferns, horsetails and whisk ferns. 2. This refers to a moss-like vascular plant with prostrate stems and has strobili that bear two types of spores. 3. These are cell wall impregnations in the endodermis of higher plants that enables the route of water and nutrients to flow via the plasma membrane.
TOPIC: SEEDLESS VASCULAR PLANTS IDENTIFICATION 1. Type of leaves that are generally larger in size and has complex venations. 2. This group is characterized by the presence of an nonvascularized root in the form rhizoids, presence of a dichotomous branching stem which resembles a whisk. 3. More commonly known as vascular plants, this refers to a large group of land plants with lignified tissues for conducting water and minerals.
TOPIC: SEEDLESS VASCULAR PLANTS IDENTIFICATION 1. The megaphyll type of leaves in ferns that both function as a photosynthetic and reproductive organ. 2. The heart-shapedflat structure in the gametophyte generation of ferns. 3. The main organ for photosynthesis in higher plants.

TOPIC: SEEDLESS VASCULAR PLANTS IDENTIFICATION 1. These are specialized cells arranged adjacent to each other and are associated with other cells to form the xylem tissue, allowing a more streamlined water conduction. 2. These are lycophytes with true roots, rhizomes, erect aerial stems, microphylls, and a dominant sporophyte stage. 3. The sporophyll in seedless vascular plants that is arranged into a cluster forming a club-shaped cone.

IDENTIFICATION OF FERNS The objective of this practical is for you to identify the genus of true ferns (Phylum Polypodiophyta) based upon their leaf blade characteristics. Instruction: 1.
