Envelope – made of host’s plasma membrane; not in all viruses 20. DNA or RNA genome; proteins needed to produce DNA/RNA 67. R factors – plasmids with genes for antibiotic resistance 81. Made up of mycelium – network of filaments called hyphae 139. Cycads – finely divided leaves, unbranched trunk, pollen and seed cones on separate plants 155. Whisk Ferns – phorophytes have dichotomously branching rhisomes and erect stems (lack true roots and leaves) 166. Vascular – sporophyte generation is dominant; contains xylem and phloem; cuticle and stomata present 201. Vessel Elements – larger, hollow and nonliving; continuous hollow pipeline from roots to leaves 208. Primary growth: increases stem or root length that occurs at the tip of the shoots and roots due to the activity of the apical meristems; occurs in all plants 210. Primary Phloem – vascular tissue that conducts dissolved sugar and organic materials 220. Epidermis – covers upper, lower surfaces of leave blade; waxy cuticle coat helps plants survive dry terrestrial conditions 221. Stomata – small pores in epidermis that permit gas exchange for photosynthesis 238. Dissolved sugar is translocated upward or downward in phloem from an area of excess sugar to a sink (storage) 257. Results in a plant embryo (seed) and an endosperm (nutritive tissue) 260. Animals eat fruit, digest, and excrete seeds in a new environment where the seed can grow into a new plant
