Week 2 assignment 1. Name five specific structural characteristics that differentiate Eudicots from Monocots. 2. Describe the function of roots in plants. 3.
Each stamen generally has a stalk called the filament (from Latin filum, meaning "thread"), and, on top of the filament, an anther (from Ancient Greek anthera, feminine of antheros "flowery," from anthos "flower"), and pollen sacs, called microsporangia. The development of the microsporangia and the contained haploid gametophytes, (called pollen grains) is closely comparable with that of the microsporangia in gymnosperms or heterosporous ferns. The pollen is set free by the opening (dehiscence) of the anther, generally by means of longitudinal slits, but sometimes by pores, as in the heath family (Ericaceae), or by valves, as in the barberry family (Berberidaceae). It is then dropped, or carried by some external agent — wind, water or some member of the animal kingdom — onto the receptive surface of the carpel of the same or another flower, which is thus pollinated. It is the part that contains the sperm

There are 900 mainly perennial species. From plants that are climbers, sub-shrubs, or plants that stems are like bamboo. Begonias vary in characteristics but most have lop- sides, ear- shaped leaves with beautiful markings. The plant flower in clusters with four to five petals. The Begonia was named after Michel Begon (1638-1710).
AP Bio 1982: Brendan Ramos In the life cycle of a fern and a flowering plant, compare and contrast each of the following: A. The gametophyte generation B. Sperm transport and fertilization C. Embryo protection A. Small multicellular male and female gametophytes are produced within the flower of the sporophyte in flowering plants. The gameteophyte of a fern consists of a free-living distinct plant called the prothallus on which structures called archegonia and antheridia produce eggs and sperm respectively.

He starts talking about the flowers and how beautiful they are, and this makes Elisa feel beautiful and valued. A stranger is noticing her “place”, her hard work. When he offers to take the chrysanthemums out of the garden, off the farm, some place to grow, she is elated. “Beautiful” (690). “Oh beautiful” (690).
