Non-Vascular Plants

Let’s look at the non-vascular plants meaning: these are simple and small plants that do not have a vascular bundle, xylem or phloem. These plants are also known as bryophytes and are said to be the most primitive form of land vegetation. Liverworts, hornworts and mosses are some of these plants. Due to the absence of vascular bundles, these plants also lack true stems, leaves, and roots and have a poor transport system. Because the transport system mainly consists of the two tissues xylem and phloem, which are responsible for carrying the water and mineral to the different parts of the plant. But in contrast to the vascular bundles, these plants have certain other specialized tissues which help them in the transportation of water and minerals. But these specialized tissues do not contain lignin; that’s why these cannot be said to be vascular tissues. Due to the absence of vascular bundles, these plants cannot grow at large heights and the absence of wood, fruits and flowers. These plants are mostly found in shady and moist areas. The green parts of these plants, known as the thallus and rhizoids, have thin filaments, which help in anchoring the plant to the ground.
