“Plant Science: An Introduction to Botany” S:1 E:16 Water Plants Came from Land

S:1 E:16 Water Plants Came from Land Learn how seagrasses, mangroves, and other aquatic plants evolved to tolerate low light levels, anaerobic and nutrient-poor sediments, and the difficulty of getting CO2 into submerged leaves and stems. They also benefit surrounding ecosystems by keeping excess nutrients from the ocean, trapping river and ocean-floor sediments, and providing habitat and protection for animals.
