- Theophrastus of Lesbos, Aristotle’s successor as head of the Lyceum, improved upon Aristotle’s botany by classifying all monocotyledons as flowering plants with: two seed-leaves in the embryo, branching leaf veins, and flower parts in multiples of 4 or 5 one seed-leaf in the embryo, branching leaf veins, and flower parts in multiples of 4 or 5 one seed-leaf in the embryo, parallel leaf veins, and flower parts in multiples of 3 or 6 two seed-leaves in the embryo, parallel leaf veins, and flower parts in multiples of 3 or 6 two seed-leaves in the embryo, branching leaf veins, and flower parts in multiples of 3 or 6Plant Diversity Know the phylum, domain and supergroup of land plants and its sister taxon. Describe at least four out of the seven derived traits of land plants. Describe and draw a general land plant life cycle (know the terms haploid, diploid, gametophyte, sporophyte, spore, meiosis, mitosis)All of the following are trends in plant evolution except; A trend towards better water conducting tissue A trend towards Sporophyte dominance and away from gametophyte dominance A trend towards seeds and away from free spores A trend away from heterospory and towards homospory
