A plant tissue made up of more than one kind of cell is called a compound or complex tissue. Xylem and phloem
Phloem
In vascular plants, phloem is the living tissue that carries organic nutrients (known as photosynthate), in particular, 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 φλοιός (p…

How do complex tissues help plants?
Modified and bound to other 6-carbon sugars, the substance becomes sucrose or a variety of other disaccharides. In this form it can be moved with small amounts of water and can be transported efficiently throughout the plant. The complex tissues of the plant aid in this overall effort to supply the roots with food as they supply the leaves with water and nutrients .
What is plant tissue?
Plant tissue is a collection of similar cells performing an organized function for the plant. Each plant tissue is specialized for a unique purpose, and can be combined with other tissues to create organs such as leaves, flowers, stems and roots. The following is a brief outline of plant tissues, and their functions within the plant.
What is the meristem of a plant?
All cells originate from one meristem or another. The apical meristem is the plant tissue which drives above ground growth, and decides the direction of the plant. Root meristems dig into the soil in search of water and nutrients. Subapical meristems divide the plant and carry leaves in different directions. Intercalary meristems provide growth from the middle of the plant, to extend the leaves upward into the sunlight.
What is the tissue that covers the epidermis of a plant?
Sometimes, another form of simple plant tissues covers the epidermis, cork. Cork is a plant tissue seen in woody plants, which dies and becomes an outer layer of bark.
How does the xylem work?
Like the xylem, the phloem consist of a variety of different cell types which work together to produce a continual interconnected passageway connecting cells of the plant. The phloem, rather than bringing water up from the roots, needs to carry sugar down to the roots and stems. With a little water from the xylem, it can complete this process. It is further aided by companion cells, which surround the actual sieve-tube. The whole structure is then supported by phloem fibers, which give the tube shape and structure.
Why are parenchyma cells important?
Parenchyma cells are sometimes considered the most important plant tissue, because they do much of the work of moving, creating, and storing the products the plants need. However, the other tissues provide the support and strength the plants needs to survive. 3.
How to classify plant tissue?
Theses tissues can be referred to as vegetative tissue. The more specialized organs of the plant, such as flowers, fruits, and seeds, are all reproductive tissue. This method of classifying plant tissues is often used by those interested in plant genetics and reproduction , as these forms of the plant are often vastly different, genetically speaking, than the vegetative portions of the plant. Plants have a life-cycle which exhibits the alternation of generations, in which the internal portions of the flower are actually small, multicellular organisms differing genetically from the parent plant. For this reason, some scientists choose to view these tissues as separate.
What are the different types of plant tissues?
Different types of plant tissues include permanent and meristematic tissues.
What are the three types of tissues in plants?

These tissues can be additionally categorised into: 1 Simple Permanent Tissue: They can be classified into sclerenchyma, collenchyma and parenchyma based on their purpose. 2 Complex Permanent Tissue: These tissues include phloem and xylem. Xylem is valuable for the transportation of water and solvable constituents. It is made up of xylem parenchyma, fibres, vessels and tracheids. Phloem is valuable in the transportation of food particles. Phloem consists of phloem parenchyma, phloem fibres, companion cells, sieve cells and sieve tubes.
