BIO153H5 Chapter Notes -Stoma, Cell Wall, Rechargeable Battery
Document Summary
Plants i: green plants: green algae and land plants; green plant and land plant are. Fungi = below ground and provided nutrients: land plants = sugars and products of photosynthesis. Similarities between green algae and land plants: chloroplasts with chlorophyll a and b, presence of beta-carotene, arrangement of thylakoids, composition - starch, sperm, peroxisomes (organelles in which specialized oxidation reactions take place) Algae similar to land plants = coleochaetophyceae (coleochaetes) and. Mosses have specialize tissues that conduct water but not true vascular tissue. Seed: consists of embryo, store of nutritive tissue, surrounded by tough protective layer. Angiosperms - seeds develop inside carpel (protective structure) Evaluating molecular phylogenies: most basal branches led to green algae (similar to land plants) Supports that land plants evolved from green algae: caraphyceae is the sister group to land plants. Supports that land plants evolved form multicellular ancestor in aquatic habitat: land plants are monophyletic.
