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. Capsule L (n) 5-9 1n Mature 2n (2n) Female "Bud" (n) Young sporophyte (2n) gametophyte (n) gametophyte (n) Embryo (2n) Antheridia water E88 Female gametophyte (n) sperm Fertilization (2n) Figure 5. 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.

Question:- Fill in the blank: Selaginella produces roots like other vascular plants, but it also has roots that arise from ________ on the plant.

The table please?

Exercise II: Monilophyta Part A: Ferns The ferns differ from other seedless vascular plants in their possession of megaphylls, larger leaves with multiple veins. Examine the many living fern sporophytes. There is much diversity in megaphyll morphology. (See also text Figures 17-23, 24, 26, and 36, pages 413, 414, 416, and 424). Identify the frond, the rhizome, and the roots. Most fern fronds are compound, with the blade divided into separate leaflets. If young leaves are present, notice how they unfold. These young leaves are often called fiddleheads. Examine the leaves for the presence of sporangia. Notice if they are grouped together in sori (singular: sorus), distributed evenly over the lower surface of the leaf, or in other patterns. The sporangia of some species may be protected by specialized outgrowths of the leaf called indusia (singular: indusium) (See text Figure 17-32, page 420). 6. Is the indusium diploid or haploid?. Obtain a small square of a fern leaf with one associated…
