Bryophytes: Mosses Mosses are also mostly-terrestrial bryophytes of Kingdom Plantae. Like all members of division (phylum) Bryophyta, mosses are eukaryotic, have chlorophyll a and b as well as xanthophylls and carotenoid pigments for photosynthesis, store starch, and have pectin-cellulose walls. Their sporic life cycle is oogamous and shares these common bryophyte traits: The dominant phase of the moss life cycle is the gametophyte (haploid). The plant is called a thallus It has "leaves" and "stems" (no xylem/phloem but hydroid/leptoid!) Anchorage is via rhizoids (single cells...no root) Gametangia are antheridia and archegonia Gametangia have a sterile jacket of cells (new!) Gametes are sperm and egg Sperm swim in free water to arrive at egg The sporophyte is parasitic (dependent!) on the gametophyte. Zygote (still in archegonium) gets nutrition from gametophyte. Sporophyte growing from zygote is nutritionally dependent (heterotrophic) on gametophyte Sporophyte consists of foot, stalk, and capsule (sporangium) Sporangium has sterile jacket surrounding sporocytes Sporocytes divide meiotically to produce spores Spores are shed by wind (usually) Spores grow into gametophyte thallus The gametophyte may reproduce asexually via bulbils or fragmentation of secondary protonema. The sporophyte does not have a method of asexual reproduction.

2. Seeds And Seed Germination Koning, Ross E. 1994. . Plant Physiology Information Website. http//plantphys.info/plant_biology/seedgerm.html. (622-2006). http://plantphys.info/Plant_Biology/seedgerm.html

Course Schedule Plant Phys Info Homepage Email Ross Koning Seeds and Seed Germination As we examine the life history of a plant we need to start somewhere. Because humans start growing plants of interest from propagules, it makes some sense to start with seeds. Of course a seed is part of a life cycle so the question of what came first, the plant or the seed comes to mind. While we cannot resolve the cycle into a linear argument from a development perspective, we CAN resolve the question from an evolution perspective. The answer is different than the one for the chicken and egg question. For plants, the plant evolved before the seed very clearly. However eggs evolved long before there were chickens on our planet. From a developmental point of view, let us for now just say that a seed germinates into a plant, the plant produces a flower, part of the flower becomes a fruit, and that fruit contains a seed. The seed can be planted to start this life-cycle over again. However, it is seed-chauvinism to start here. Many plants do not reproduce via seeds at all. Seed Structure A seed consists of three parts: a Dormant Embryo , a Storage Tissue , and a Seed Coat . Not every seed that has evolved on this planet has precisely the same structure. In some seeds, the endosperm is retained as the storage tissue. In other seeds, the endosperm is more or less used up to put storage chemicals into the embryo itself (commonly in the cotyledons). Below is a diagram of two hypthetical seeds. The upper seed shows a dicot that lacks endosperm; its storage material (blue) is held in the cotyledons That would be an

Fungi The fungi lack photosynthetic pigments. As a group, they are heterotrophic and must obtain their food either from dead organic matter (saprophytically) or from living organisms (parasitically). Approximately 100,000 species have been described, and these are very widely distributed, particularly on land, although there are a number of common water-growing species. You will attempt to get some idea of the diversity of form that occurs among the fungi. The fungi can be divided into six divisions: Myxomycophyta, Chytridomycota, and Oomycota (in kingdom Protista), Zygomycota, Ascomycota, and Basidiomycota (in kingdom Fungi). Classification of fungi is controversial and based primarily on their sexual reproduction. A seventh artificial division, Deuteromycota, includes all species for which no sexual stages are known at present. Deutero- means "duty"; thus mycologists consider it their duty to discover the sexual stages and classify these species into the natural divisions...easier said than done. Most are clearly members of Ascomycota and a few are clearly members of Basidiomycota. The true fungi differ from the slime molds in producing a vegetative body which is composed of masses of fine branched filaments often having a cottony appearance. A single filament is called a
