Unlike simple permanent cells which look the same and are made up of one type of cells, complex permanent tissues are made up of more than one type of cells. All these cells coordinate to perform a common function. Complex Tissues Tissues composed of more than one cell type are generically referred to as complex tissues. There are at least 200 different cell types in the human body. Complex tissue is composed of more than one kind of cells. In this article, we explain their function, what they are made of, and the types of cells involved. Multicellular organisms are organised into increasingly complex parts. These tissues vary in their structure, function, and origin.The animal tissues are divided into epithelial, connective, muscular and nervous tissues. In order, from least complex to most complex: They are two types, namely Xylem tissue and Phloem tissue. There are four main tissues in the body – epithelium, muscle, connective tissue and nervous tissue. Some that you'll need to know best include specialized blood cells, specialized nerve cells and specialized … Complex Permanent Tissues: The complex tissue consists of more than one type of cell having a common origin. The four basic tissue types are epithelial, muscle, connective, and nervous tissue. They transport water, salt and prepared food material to various parts of the plant body. In Plants. - Xylem - Phloem (bast) Xylem and Phloem are also called vascular tissue and together they constitute vascular bundles. Xylem and phloem are the two most important complex tissues in a plant, as their primary functions include the transport of water, ions and soluble food substances throughout the plant. Types of Animal Tissue. Xylem Tissue. Tissue Membranes. Xylem is a multifaceted tissue forming a part of the vascular bundle. Each tissue type has a characteristic role in the body: The different types of animal tissues include: The 4 Basic Tissue Types in the Human Body www.exploringnature.org Tissues are groups of cells with a common structure (form) and function (job). I. EPITHELIUM Functions (jobs): 1) It protects us from the outside world – skin. The simplest living creatures are single cell creatures, but in complex life forms, such as human beings, cells also exist in the tissue level. While the plant lifecycle sometimes seems alien and complex, the process of cell differentiation is very similar. Vascular tissue is an example of a complex tissue, and is made of two specialized conducting tissues: xylem and phloem. These different types of cells coordinate to perform a function. Through cell differentiation, tissues as different as brain tissue and muscle are formed from the same single cell. A tissue membrane is a thin layer or sheet of cells that either covers the outside of the body (e.g., skin), lines an internal body cavity (e.g., peritoneal cavity), lines a vessel (e.g., blood vessel), or lines a movable joint cavity (e.g., synovial joint). The animal cells are grouped together to form animal tissues. While there are different hormones involved, all plants also develop from a single cell. The complex tissues are generally heterogeneous in nature, being com­posed of dissimilar types of cell elements. Xylem and Phloem are complex permanent tissues and are found in the vascular bundles in the plants. Differentiation allows cells to develop into the four major tissue types: epithelial tissue, nervous tissue, connective tissue and muscle tissue. Xylem tissue transports water and nutrients from the roots to different parts of the plant, and includes three different cell types: vessel elements and tracheids (both of which conduct water), and xylem parenchyma. Complex Permanent Tissue. Complex tissues are made up of more than one type of cells and they work together as a unit. Complex tissues are of two types: Xylem or wood and phloem or bast. Tissues are groups of similar cells that have a common function. Cells, tissues, organs and systems. Complex tissues are of two types.
