  1. Dovydas Mockevicius Project Flowering plants (Angiospermae)

  2. About Angiosperms • The flowering plants or angiosperms (Angiospermae or Magnoliophyta) are the most diverse group of land plants. The flowering plants and the gymnosperms are the only extant groups of seed plants. The flowering plants are distinguished from other seed plants by a series of apomorphies, or derived characteristics. • The ancestors of flowering plants diverged from gymnosperms around 245–202 million years ago, and the first flowering plants known to exist are from 140 million years ago. They have become widespread around 100 million years ago, but replaced conifers as the dominant trees only around 60-70 million years ago

  3. Angiospermae life cycle

  4. Rose • A rose is a perennial flower shrub or vine of the genus Rosa, within the family Rosaceae, that contains over 100 species and comes in a variety of colours. The species form a group of erect shrubs, and climbing or trailing plants, with stems that are often armed with sharp prickles. Most are native to Asia, with smaller numbers of species native to Europe, North America, and northwest Africa. Natives, cultivars and hybrids are all widely grown for their beauty and fragrance.

  5. Venus Fly Trap(Dionaeamuscipula) • The Venus Flytrap,Dionaea muscipula, is a carnivorous plant that catches and digests animal prey—mostly insects and arachnids. Its trapping structure is formed by the terminal portion of each of the plant's leaves and is triggered by tiny hairs on their inner surfaces. When an insect or spider crawling along the leaves comes into contact with one or more of the hairs twice in succession, the trap closes. The requirement of redundant triggering in this mechanism serves as a safeguard against a waste of energy in trapping objects with no nutritional value.

  6. Lotus(Nelumbo nucifera) • Nelumbo nucifera, known by a number of names including Indian lotus, sacred lotus, bean of India, or simply lotus, is a plant in the Nelumbonaceae family. Botanically, Nelumbo nucifera (Gaertn.) may also be referred to by its former names, Nelumbium speciosum (Wild.) or Nymphaea nelumbo. This plant is an aquatic perennial. Under favorable circumstances its seeds may remain viable for many years, with the oldest recorded lotus germination being from that of seeds 1300 years old recovered from a dry lakebed in northeastern China.
