BLG 144 Chapter Notes - Chapter 30: Non-Vascular Plant, Green Algae, Embryophyte
Document Summary
Green plants make up two major types of organisms: green algae- important photosynthetic organisms that live in aquatic habitats like lake, ponds, and other freshwater settings, land plants- important photosynthetic synthesizers in terrestrial environments. Land plants were the first organisms that could thrive with their tissues completely exposed to air instead of being partially or completely submerged water. Land plants are the dominant primary producers in terrestrial ecosystems. Plants provide our food, fuel, fibres, building materials, and medicines that we use. A: because (1) they are the closest living relative to land plants and form a monophyletic group (2) the transition from aquatic to terrestrial life occurred when land plants evolved from green algae. Research programs focus on two types of land plants that cause problems for people: 30. 1 why do biologists study the green algae and land plants: weeds that decrease the productivity of crop plants, newly introduced species that invade and then degrade natural areas.
