- 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 6arrow_forwardPut the following 3 fictional plants in order from earliest to most recent according to their characteristics: A. The Terpad Plant: This plant reproduces using spores and has proper leaves and vascular tissue. B. The Feltris Plant: The Feltris plant lives in moist environments since it doesn't have any vascular tissue to maintain hydration throughout the plant. This plant has no roots either but has small root-like structures called rhizoids which help anchor them to the ground. Water is also required in order for fertilization. C. The Lancelot Plant: This plant can grow in either moist or dry environments, has true roots, stems and leaves and reproduces via seeds which develop within an ovary.arrow_forwardIn the life cycle of a bryophyte, represent(s) the gametophyte (haploid) form and represents the sporophyte (diploid) form.

- Early botanists admired ferns but found their life cycle perplexing. In the 1700s, they learned to propagate ferns by sowing what appeared to be tiny dustlike “seeds” from the undersides of fronds. Despite many attempts, the scientists could not find the pollen source, which they assumed must stimulate these “seeds” to develop. Imagine you could write to one of these botanists. Compose a note that would clear up the confusion.arrow_forwardA team of botanists discovers a new species of plant in a tropical rain forest. After observing its anatomy and life cycle, they note the following characteristics and observations: 1. Presence of pollen cones and ovulate cones 2. Diploid-dominant 3. Seeds 4. vascular tissues 5.
