TEST 2 VOCABULARY Alteration of generations o A life cycle, typical of plants, in which a diploid sporophyte (spore-producing) generation alternates with a haploid gametophyte (gamete-producing) generation Angiosperm o A flowering vascular plant Anther o A structure in which male sex cells are produced; found in nonvascular plants and certain seedless vascular plants. Ascomycete o A member of the fungus phylum Ascomycota, whose members form sexual spores in a saclike case known as an ascus. Ascus o A saclike case in which sexual spores are formed by members of the fungus phylum Ascomycota Aseptic o Fungi are considered aseptic if they don’t have septa Astrocarp o The fruiting body for ascomycete o Underneath the fruiting bodies are the mycelium Autotroph o “Self-feeder”; normally a photosynthetic organism; a producer Basidiomycete o A member of the fungus phylum Basidiomycota, which includes species that produce sexual spores in club-shaped cells known as basidia. Basidium/Basidia o A diploid cell, typically club-shaped, formed by members of the fungus phylum Basidiomycota; produces basidiospores by meiosis Binary Fission o The process by which a single bacterium divides in half, producing 2 identical off spring Carpel o The female reproductive structure of a flower o Composed of stigma, style, and ovary Chitin o A compound found in the cell walls of fungi o Composed of nitrogen-containing, modified glucose molecules Chytrid o A member of the fungus phylum Chytridomycota, which includes species with flagellated swimming spores.

o A fungus of the division Basidiomycota, whose members (which include mushrooms, puffballs, and shelf fungi) reproduce by means of basidiospores. Coleoptile o A sheath surrounding the shoot in MONOCOT seedlings that protecs the shoot from abrasion by soil particles during germination Conjugation o In prokaryotes, the transfer of DNA from one cell to another via a temporary connection o In single celled eukaryotes, the mutual exchange of genetic material between 2 temporarily joined cells Cotyledon o A leaf like structure within a seed that absorbs food molecules from the endosperm and transfers them to the growing embryo o Also called seed leaf Dicot o A type of flowering plant characterized by embryos with 2 cotyledons, or seed leaves, that are usually modified for food storage Diploid o A cell with pairs of homologous chromosomes Double fertilization o The fusion of 2 sperm nuclei with the nuclei of 2 cells of the female gametophyte o One sperm nucleus fuses with the egg to form the zygote o The 2 nd sperm nucleus fuses with 2 haploid nuclei of the central cell to form a
