Plant evolution is an aspect of the study of biological evolution, predominantly involving evolution of plants suited to live on land, greening of various land masses by the filling of their niches with land plants, and diversification of groups of land plants.
The evolution of plants has resulted in a wide range of complexity, from the earliest algal mats of unicellular archaeplastids evolved through endosymbiosis, through multicellular marine and freshwater green algae, to spore-bearing terrestrial bryophytes, lycopods and ferns, and eventually to the complex seed-bearing gymnosperms and angiosperms ...
There are four key stages in the timeline of plant evolution. These are: The evolution of ancestral streptophyte algae and the first land-dwelling plants. The development of vascular systems. The emergence of seeds and pollen. The rise of flowering plants.
12 lip 2020 · Today, flowering plants (or angiosperms) make up around four-fifths of all the green plants on Earth, but for billions of years they weren't around at all. Now biologists have been able to fully chart the rapid rise of angiosperms over the last 140 million years.
Constructing a Timeline of Plant Evolution. Use this photo as a guide to creating an interactive timeline. Refer to Geologic Time Scale charts. A good resource is http://www.ucmp.berkeley.edu/help/timeform.php. Use the “Plant Timeline Cards” found at the end of this document.
Plants have been on Earth for much longer than animals and over time the process of evolution by natural selection has led to over 390, 000 different species of plants. These plants have a huge variety of adaptations to survive in the different habitats they live in.
1 sie 2010 · In 2010 the University of Cambridge Department of Plant Sciences developed an online interactive timeline tool allowing students studying Plant Evolution to visualise the circumstances and factors contributing to the current diversity of plant life.
