BIO153H5 Lecture Notes - Lecture 9: Arecaceae, Charophyceae, Xylem
Document Summary
Volcanism is the reason behind the elimination of snowball earth. Fungi are responsible for the carbon cycle. All land plants have a common origin with the glaucophyte algae. Angiosperms and gymnosperms - same common ancestry. True angiosperms or flowering plants in the fossil record until 150 million years ago. Green plants consist of green algae and land plants. Green algae in the past considered algae but now along with land plants. Transition from aquatic to terrestrial life occurred when land plants evolved from green algae. Primary consumers: herbivores that consume the producers/plants. Derived from wild species via artificial selection. Wheat is the largest crop produced (from north america - not native to this region) The growth of rice is becoming a problem because our world is becoming drier (droughts) Cooking food made it easy to chew, to digest. China is investing in hydropower, hydrogen power, and electrical power. Coal forms by the burying of materials (peat when put pressure)
