Summary Introduction
Introduction:
Plant evolution is the subset of evolutionary phenomena that concern plants. The study of plant evolution attempts to explain how the present diversity of plants arose over geologic time. It includes the genetic change and the consequent variation that often results in variation. Plants are thought to have evolved from an aquatic green algae protest. Later they evolved important adaptations for land, including vascular tissues, seeds, and flowers. Each of these major adaptations made plants better suited for life on dry land and much more successful.

Students have asked these similar questions
Some ancestral plants had a difficult transition to land, as challenges to survive caused plant evolution to develop very specialized adaptations over an extended amount of time. These are some
of the challenges that plants faced:
A. Avoiding desiccation
B. Supporting larger bodies (against gravity)
C Internally transporting substances
D. Keeping gametes wet
E. Keeping embryos wet
For each of the above challenges. provide a structure/adaptation that plants have developed which mitigates that specific challenge. Must describe a structure or trait for all!
Which of the following statements is NOT true of the stems of vascular plants?
a. Stems are composed of repeating segments, including nodes and internodes.
b. Primary growth only occurs at the shoot apical meristem.
c. Vascular tissues may be arranged on the outside of the stem or scattered throughout the stem.
d. Stems can contain stomata.
Which of the following is the MOST likely explanation for the evolutionary success of angiosperms?
A.
Angiosperms have complex and successful interactions with animals leading to effective pollination and seed dispersal.
B.
Angiosperms have a vascular system that allows plants to grow tall and spread spores farther.
C.
Angiosperms have stomata that allow conservation of water.
D.
Angiosperms developed seeds and pollen, which allow reproduction to be independent from water.

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 bryophytes (e.g. mosses) and seedless vascular plants (e.g. ferns).
