Phloem and xylem
This article is about vascular tissue in plants. For transport in animals, see Circulatory system. Vascular tissue is a complex conducting tissue, formed of more than one cell type, found in vascular plants. The primary components of vascular tissue are the xylem and phloem. These two tissues transport fluid and nutrients internally. There are also two meristems associated with vascular tissue: the vascular cambium and the cork cambium. All the vascular tissues within a particular plant together constitute the vascular tissue system of that plant. The cells in vascular tissue are typically long and slender. The vascular tissue in plants is arranged in long, discrete strands called vascular bundles. These bundles include both xylem and phloem, as well as supporting and protective cells. In stems and roots, the xylem typically lies closer to the interior of the stem with phloem towards the exterior of the stem. Answers. Relevance. Rating Newest Oldest. Best Answer: In vascular plants, xylem is one of the two types of transport tissue, phloem being the other. The word xylem is derived from classical Greek word (xylon), wood, and indeed the best known xylem tissue is wood, though it is found throughout the plant. Its basic function is to transport water. In vascular plants, phloem is the living tissue that carries organic nutrients (known as photosynthate), particularly sucrose, a sugar, to all parts of the plant where needed. In trees, the phloem is the innermost layer of the bark, hence the name, derived from the Greek word (phloos) bark Vascular tissue is found in all of a plant's vegetative organs-that is, the roots, stems, and leaves. Xylem and phloem start out as special type of tissue called cambium. You can think of cambium tissue cells as similar to stem cells-when they divide, they have the ability to become different kinds of tissue. The tissue starts out as vascular cambium, or undifferentiated cells that can become either xylem of phloem. Vascular tissue is found in all the plant's vegetative organs, the roots, stems, and leaves, and it's patterns can determine a monocot or dicot angiosperm.

Vascular plants (from Latin vasculum: duct), also known as tracheophytes (from the equivalent Greek term trachea) and also higher plants, form a large group of plants that are defined as those land plants that have lignified tissues (the xylem) for conducting water and minerals throughout the plant. 1 Vascular plants have vascular tissues which distribute resources through the plant. 2  This feature allows vascular plants to evolve to a larger size than non-vascular plants, which lack these specialized conducting tissues and are therefore restricted to relatively small sizes. The vascular tissue system is important in transport. The vascular tissue system is composed of the xylem (transport of water and dissolved minerals) and phloem (transport of food-usually sucrose and other sugars-, nitrogen containing compounds, and hormones). The xylem and phloem in the primary plant body are usually closely associated in the form of vascular bundles.  There are two types of vascular tissue: xylem, which moves water, and phloem, which moves food. These structures are arranged differently in monocots and dicots. In monocots, which are flowering plants with only one seed leaf, the xylem and phloem are found in paired bundles throughout the stem. Let's now look at some specialized types of vascular tissue found in plant stems that is surrounded by the ground tissue. Previously, the concept of vascular tissue was addressed. Remember that vascular tissue is the tissue used to transport water and nutrients throughout a plant. It acts like roads and plumbing, moving around nutrients and water needed by the plant. There are two types of vascular tissue: xylem and phloem. Xylem transports water and dissolved minerals, while phloem transports food. Previously it was pointed out that an easy way to remember which vascular tissue is which is that 'phloem' and 'food' both start with the same sound Phloem and xylem are the two main types of vascular tissue found in plants. Xylem is the tissue that mainly carries water, and a few minerals, in the system. Phloem is the tis … sue that carries photosynthetic materials through the plant. One kind of vascular tissue is called the xylem and is responsible for the upward transport of nutrients and water. Another is phloem which is responsible for the downward tra … nsport of photosynthates, plant hormones and other control substances. + 15 others found this useful. Tina Hunt.
