Define and compare gymnosperms and cycads.
Gymnosperms: They are naked seed, that are developed on the surface of specialized leaves and they are cone bearing in nature. develop either on the scale or cones (leaf-like appendages). The largest group of living gymnosperms are conifers and smallest is ginkgo, it is a single living plant species found in China.
Cycads: Cycads are a group of gymnosperm trees and shrubs. They are woody, seed producing plants with no flowers or fruit. Cycads often look similar to palm trees with branchless stems and crown of large compound leaves and a stout trunk, and because of their large attractive leaves, many cycads have found a home in public and private gardens around the world. The cycads are gymnosperm plants and hence sit in the class of plants known as Pinopsida.
Gymnosperms (Cycads, Ginkgo, and conifers) identify and state the differences of: cycad, Ginkgo, or conifer - Know the definition and function of these terms AND whether it is haploid (N) or diploid (2N) : columnar trunk, bulbous trunk, male strobilus/i, female strobilus/i, pollen sacs (also called microsporangium/ia), pollen grains, megasporangium/ia, ovule, seed, stem, megasporophyll, microsporophyll, long shoots, short shoots, female cone, scale, winged seed - Know the definition and function of: integument, megasporangium/nucellus, archegonium with egg, micropyle, megaspore wall, pollen...
Classify each label as a characteristic of, or a taxon belonging to the gymnosperms, eudicots, and/or monocots. Labels may be used more than once. Gnetophytes and ginkgo Embryos develop two cotyledons Orchid Seeds develop inside ovary Conifers following fertilization Speeies such as corn whose pollen grains have only one spore Angiosperm (monocot) Cycads Produce both seeds and pollen Oak trees Angiosperm (eudicot) Gymnosperm
