BIO152H5 Chapter Notes - Chapter 30: Green Algae, Non-Vascular Plant, Vascular Plant
Document Summary
Green algae: closest living relative to land plants and form a monophyletic group with them, transition from aquatic to terrestrial life occurred when land plants evolved from green algae. Ecosystem: all organisms in a particular area along with physical components of the environment such as atmosphere, precipitation, surface water, sunlight, soil and nutrients. Plants add to quality of atmosphere, surface water, soil, and other physical components of an ecosystem. Stated another way, plants alter the landscape in ways that benefit other organisms: Fine roots produced by trees help hold particular soil particles in place. By taking up nutrients in soil, plants prevent nutrients from being blown or washed away. Reduce impact of winds that dry out landscapes. Green plants are the key to the carbon cycle on land. Take co2 from atmosphere and reduce it t make sugars. Plants provide humans with food, fuel, fibre, building materials, and medicines. Analyzing morphological traits: non-vascular plants: include hepaticophyta (liverworts), anthocerophyta (hornworts), and.
