In plants and animals groups of cells called tissues carry out specific functions. A group of cells having common origin, similar structure and performing a definite function is called a tissue. CHAPTER - 6 TISSUES CLASS :- IX MADE BY :- SHIVA PRASAD SCHOOL :- KV 2 SADRAS KALPAKAM 2. They do not have the cytoplasm and the nucleus. 1. Collenchyma Sclerenchyma 1. Chapter-wise NCERT Solutions For Class 9 Science Chapter 6 Tissues (Biology) solved by Expert Teachers as per NCERT (CBSE) Book guidelines. Meristematic tissue is the dividing tissue present in the growing regions of the plant. Home » Class 9 » Tissues » Permanent tissue. 2. 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”. Mention the most abundant muscular tissue found in our body. They are classified as simple and complex tissues. Common examples are xylem and phloem. Parenchyma, collenchyma and sclerenchyma are three types of simple tissues. Question 3. Permanent tissues are derived from meristematic tissue once they lose the ability to divide. The sclerenchymatous cells do not have such thickenings. Complex tissues are made of more than one type of cells that work together as a unit. tissues 1. The “tissue” is very crucial in order to understand Biology topics in Class 10 and in higher secondary classes. What are Tissues? For example, groups of bone cells form bone tissues and muscle cells form muscle tissue. The cells are dead. State its function. 1) Tissues :- Tissue is a group of cells having similar structure and function. 3. 2. The tissues are dead which makes the plant hard and stiff (eg. Last Updated on March 20, 2019 By Mrs Shilpi Nagpal 3 Comments. ... Collenchyma You must have seen that some plant parts can bend without breaking. This feature is due to the presence of a mechanical tissue called collenchymas. Plants and animals are made up of many different kinds of tissues. Also, see Tissues Class 9 Notes, Video Explanation and Question Answers. These are difference between collenchyma and sclerenchyma. Collenchyma cells are elongated cells with thickened cell walls that provide structure and support for plants. 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. Get CBSE Class 9 Chapter 6 Tissues. Answer. Permanent tissue. CBSE Ncert Notes for Class 9 Biology Tissues. Tissues are found in plants and animals. SCLERENCHYMA.
