You might just think that plants are pretty and nice to smell.
But they also create the oxygen that allows us to breathe and survive. These life-giving creatures are separated into two main categories: vascular and non-vascular.
Most plants are vascular and absorb water through their roots. A vascular plant reproduces using seeds and comes in a variety of forms. One of the largest species of vascular plants is flowering plants, of which there are over 285,000 known types including sunflowers and orchids. Another vascular species, conifers, have seeds inside a protective cone. Ferns, a third kind of vascular plant, also have a large number of subspecies- approximately 12,000.
All vascular plants have unique compositions. For example, inside a stem of a vascular plant there are two sets of tubes. The xylem, the first set of tubes, moves water and minerals from the plant's roots to its leaves. The phloem, the second set of tubes, moves sugar all around the plant. These tubes help the plant function.
In contrast, non-vascular plants multiply because of spores. They include mosses, warts, and a specific group of green algae called chlorophyta. Like vascular plants, non-vascular plants have interesting make ups. Mosses grow on the ground and have small leaves, with no tree roots to anchor them, for example. Worts have a ribbon-like body called a thallus or a series of stacked leaves. And chlorophyta, which can be big or small, only grow in some form of water.
Because plants are necessary for us to breathe, it’s important that we understand and learn about them.
