Lecture 14: plants wednesday, january 31, 2018 - sinha. Midterm 2 material! challenges and advantages to life on land de ning features of plants algal relatives of land plants transition characteristics synapomoprhies of land plants plants, green plants, land plants. Q: planetary co2 leves are linked to seasonal variation in vegetation. Key concepts primary endosymbiosis that led to cholorplasts produced the rst photosynthetic eukaryotes (plantae. everyone else was secondary and tertiary) key adaptations permitted plants to colonize land vascular tissues led to rapid diversi cation of land plants. Plantae plantae are photoautotrophs plantae is a monophyletic clade most photosynthesis happens in the ocean! but land plant photosynthesis is also important plants need oxygen to survive. Plant cells have mitochondria, which uses oxygen for oxidative phosphorylation. At the roots, need oxygen major clades of plantae evolved from the rst photosynthetic eukaryote key evolutionary innovations evolved among aquatic plantae land plants fall into ten major clades.
