Complex tissues are of two types: Xylem or wood and phloem or bast. Answer: Complex tissues are made up of more than one type of cells. It is characterized by ordered and densely packed collection of fibers and cells. It consists of large number of oval and rounded adipose cells (adipocytes) filled with fat globules. The blood plasma does not contain protein fibres but contain cells called blood corpuscles or blood cells. It transports water and nutrients from the roots to the leaves of the plant. (b) Muscular tissue are made up of muscles, help in movement. The blood plasma does not contain protein fibres but contain blood cell or corpuscles.Plasma is a complex fluid which contains inorganic salts and organic compounds. Stomata present in the epidermis allow gaseous exchange to occur during photosynthesis and respiration. Plant tissues come in several forms: vascular, epidermal, ground, and meristematic. The cells of a single tissue have the same structure and perform a common function. Protoderm gives rise to epidermal tissue, procambium gives rise to primary vascular tissues and ground meristem gives rise to cortex and pith. Complex tissues are made of more than one type of cells. The dendrites receive impulses and the axon takes impulses away from the cell body. Epithelial tissues help in elimination of waste products. The tendons are tissues that are not very flexible but are some of the most strong tissues in the body. Muscles are of three types: The tissues that are composed of a mixture of cells and neurons are known as Nervous Tissues. It is an insulator and stores fat. Hence, cells group together to form functional organs known as tissues. Cork cells are dead cells without having intercellular spaces. D-5 Road No. The cells of the meristematic tissue are similar in structure and have thin cellulose cell walls. The skin and lining of buccal cavity, blood vessels, alveoli of lungs and kidney tubules are made of epithelial tissue. Answer: Xylem and Phloem Provide mechanical support to the organs. ‘something’ and helping you leverage it! From the distal part of cyton arises a very long process called axon. Plants, too, are built of tissues, but not surprisingly, their very different lifestyles derive from different kinds of tissues. Xylem and phloem are both conducting tissues and also known as vascular tissues; together both them constitute vascular bundles. Complex tissues are of the following two types: (a) Xylem: Xylem is a vascular and mechanical tissue. The place of injury in plants is healed up by the formation of new cells by meristems. 1. It protects plants from external injury and infection. Function: They form primary structure of the plant. In our tissues class 9 notes, the next important topic is of Animal Tissues. There are so many different types of complex machines. All three types of plant cells are found in most plant tissues. Permanent tissue is composed of cells that have lost the power of dividing and has attained a definite form and shape. 91 Springboard, Lotus Building Given below are the links of some of the reference books for class 9 science. D-5 Road No. The main functions of connective tissue are binding, supporting and packing together different organs of the body. Companion cells of the phloem are meant to supplement the function of the sieve tubes, while phloem fibers impart structural flexibility to the plant. They are located at the base of leaves or internodes, e.g., stems of grasses and other monocots and below the nodes (e.g., mint). (c) Connective tissue connects the different organs in the body. Both are conducting tissues and form a vascular bundle. Answer: Stomata helps in exchanging of the gases with the atmosphere and Transpiration also takes place through stomata. For example, multicellular protists, ancient eukaryotes, do not have cells organized into tissues. The next important mention in our tissues class 9 notes is this type of tissue. Muscle cells are typically arranged in parallel arrangement allowing them to work together effectively. Tissues are the first step towards division of labour in complex organisms. These are present along the lateral side of the stems and roots. It is a fibrous connective tissue. Xylem is composed of cells of four different types: 1.

It is also concerned with body defense, fat storage, repair etc. These are present at the tips of roots, shoots, branches and leaves. Aerolar connective tissue is found between the skin and muscles, around blood vessels and nerves and in the bone marrow. Also, the tissue structure is not specialized. 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. It helps plants in the exchange of gases through the stomata, and also helps in regulating the temperature of the plant. Photosynthesis produces the sugar glucose. As such, it connects one bone with another and a bone with a muscle. Complex. Cells of this tissue are elongated and flattened. ‘ (a) Epithelial tissue present on the outer and inner lining of the body. Plot No. (b) Meristmatic cells have a prominent muscles and dense cytoplaom but they lack muscles (c) We get crunchy and granular feeling, when we chew pear fruit.

Tissues become organized to form organs and organs into organ systems. Connective tissues can be rigid, dense, or fluid. It provides rapid diffusion of oxygen and nutrients from blood vessels. Epithelial cells protect the underlying cells from mechanical and chemical injuries and bacterial or viral infection. The red blood cells have a pigment known as haemoglobin, which helps in the transportation of oxygen to various parts of the body. Formation of tissues has brought about division of labour in multicellular organisms. CBSE Class-9 Revision Notes and Key Points. Let’s look at their descriptions in the tissues class 9 notes: The epidermis of the leaves of any plant contains microscopic, pore like structures which are known as stomata. They are two types, namely Xylem tissue and Phloem tissue. Cartilage are present at the joints of bones, in external ear (pinna), nose tip, epiglottis, trachea etc. Such a parenchyma type is called. The main function of white blood cells and platelets is to fight diseases and clot blood in cases of injury, respectively.
