SCLERENCHYMA. 1) Tissues :- Tissue is a group of cells having similar structure and function. These are difference between collenchyma and sclerenchyma. Parenchyma, collenchyma and sclerenchyma are three types of simple tissues. Complex tissues consist of parenchyma and sclerenchyma cells. Tissues are found in plants and animals. State its function. NCERT Exemplar solution for class 9 science Chapter 6 Tissues is a premier study material that will help the students in understanding the concepts of the chapter “Tissue”. For example, groups of bone cells form bone tissues and muscle cells form muscle tissue. CBSE Class 9 Science Chapter 5 Tissues Exercise Questions with Solutions to help you to revise complete Syllabus and Score More marks. Mention the most abundant muscular tissue found in our body. There are four types of collenchyma cells: tangential, annular, lacunar, and angular. This feature is due to the presence of a mechanical tissue called collenchymas. tissues 1. Plants and animals are made up of many different kinds of tissues. The “tissue” is very crucial in order to understand Biology topics in Class 10 and in higher secondary classes. Question 1 Write down the functions of Sclerenchyma? Permanent tissues are derived from meristematic tissue once they lose the ability to divide. Collenchyma cells are elongated cells with thickened cell walls that provide structure and support for plants. Complex tissues are made of more than one type of cells that work together as a unit. The tissues are dead which makes the plant hard and stiff (eg. The collenchyma cells have thickening of cellulose and pectin at the corner of its cells. Answer. 2. Get CBSE Class 9 Chapter 6 Tissues. ... Collenchyma You must have seen that some plant parts can bend without breaking. Meristematic tissue is the dividing tissue present in the growing regions of the plant. The sclerenchymatous cells do not have such thickenings. Aerenchyma: A spongy or soft plant tissue with large air spaces found between the cells of the stems and leaves of many aquatic plants, which allows exchange of gases between the shoot and the root Chlorenchyma: In some cases the parenchyma cells contain chloroplasts and are called as chlorenchyma.These cells are meant for photosynthesis. Common examples are xylem and phloem. Also, see Tissues Class 9 Notes, Video Explanation and Question Answers. They are generally found below epidermis of dicot stem and petiole.
