Question 17

Question 1Define the terms given below:TissueOrganOrgan systemSclerenchymaCartilage

Accepted Answer

Tissue — A group of similar cells which are specialised to perform specific function is known as tissue. For example muscle tissue, skin tissue.Organ — A differentiated structure formed by group of similar tissues, which is specialised to perform a specific function is called an organ.Organ system — An organ system is a group of organs that work together to perform a specific function or set of functions in the body. For example, the digestive system.Sclerenchyma — Sclerenchyma is a simple supportive permanent tissue composed of long, narrow and thick-walled dead cells. It provides strength to the plant parts.Cartilage — Cartilage is a supportive connective tissue that covers the ends of bones, and gives support to certain organs like the nose, ear, and trachea. It consists of a clear ground substance (matrix), which contains a large number of spaces, each occupied by one or more cells.

Question 3Write the exact location of each of the following tissues :CollenchymaMeristematic tissueSquamous epitheliumCardiac musclesNervous tissue

Accepted Answer

Collenchyma is found in the leaf stalks and below the epidermis of stems.Meristematic tissues are found at all growing points in a plant, like the tip of roots, stems and branches, where growth in length occurs.Squamous epithelium is found in the cells of the outer layer of skin.Cardiac muscles are found only in the walls of the heart.Nervous tissue constitutes the nervous system.

Question 19

Question 4Mention the specific function of each of the following tissues :Areolar tissueParenchymaXylemTendonAdipose tissue
