They are classified as simple and complex tissues. CHAPTER - 6 TISSUES CLASS :- IX MADE BY :- SHIVA PRASAD SCHOOL :- KV 2 SADRAS KALPAKAM 2. In plants and animals groups of cells called tissues carry out specific functions. Parenchyma, collenchyma and sclerenchyma are three types of simple tissues. The cells are dead. Mention the most abundant muscular tissue found in our body. For example, groups of bone cells form bone tissues and muscle cells form muscle tissue. State its function. CBSE Ncert Notes for Class 9 Biology Tissues. The cells of collenchyma are living and have the cytoplasm and the nucleus. 1. They do not have the cytoplasm and the nucleus. 1) Tissues :- Tissue is a group of cells having similar structure and function. 2. 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. ... Collenchyma You must have seen that some plant parts can bend without breaking. Collenchyma cells are elongated cells with thickened cell walls that provide structure and support for plants. Tissues are found in plants and animals. 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”. Permanent tissues are derived from meristematic tissue once they lose the ability to divide. These are difference between collenchyma and sclerenchyma.

The “tissue” is very crucial in order to understand Biology topics in Class 10 and in higher secondary classes. Permanent tissue. Last Updated on March 20, 2019 By Mrs Shilpi Nagpal 3 Comments. The collenchyma cells have thickening of cellulose and pectin at the corner of its cells. The sclerenchymatous cells do not have such thickenings. SCLERENCHYMA. 2. This feature is due to the presence of a mechanical tissue called collenchymas. Common examples are xylem and phloem. Plants and animals are made up of many different kinds of tissues. The tissues are dead which makes the plant hard and stiff (eg. Also, see Tissues Class 9 Notes, Video Explanation and Question Answers. Home » Class 9 » Tissues » Permanent tissue.
