Summary Introduction
Introduction:
The plant kingdom consists of multicellular organisms, most of which are able to perform photosynthesis. The plant kingdom is divided into several phyla to accommodate diverse plant groups. In earlier times, plants lived in water; however, as they evolved, they adapted to the terrestrial life.

- From the following list, which group has many members with woody, perennial stems that show annual growth increments in secondary xylem? Select one: a. Equistems b. perennial Monocots c. Bryophytes d. Pteridophytes e. Eudicotsarrow_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_forwardCompare and contrast the three phyla of bryophytes using the specified bases in the Table below.
