Simply Seaweed
Have you ever wondered if plants that lived underwater still needed sun? Well, seaweed does. Even though it's an ocean plant, it still has photosynthesis. Strangely, though, it doesn't have a vascular system.
Vascular System
In plants, a vascular system transports sap. In humans, blood. Instead, the entire seaweed plant absorbs minerals and nutrients directly from the ocean water. That way, it does not need a system in place to carry sap through its body. Water baby's breath (Alisma subcordatum) enjoys a wet environment. Find it among our wetland plants.
