CBSE Ncert Notes for Class 9 Biology Tissues. 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. Meristematic tissue is the dividing tissue present in the growing regions of the plant. They are classified as simple and complex tissues.

Question 1 Write down the functions of Sclerenchyma? The collenchyma cells have thickening of cellulose and pectin at the corner of its cells. The “tissue” is very crucial in order to understand Biology topics in Class 10 and in higher secondary classes. 1. SCLERENCHYMA. Permanent tissue. These are difference between collenchyma and sclerenchyma. ... Collenchyma You must have seen that some plant parts can bend without breaking. In plants and animals groups of cells called tissues carry out specific functions. tissues 1. Complex tissues consist of parenchyma and sclerenchyma cells. CHAPTER - 6 TISSUES CLASS :- IX MADE BY :- SHIVA PRASAD SCHOOL :- KV 2 SADRAS KALPAKAM 2. Question 3. Last Updated on March 20, 2019 By Mrs Shilpi Nagpal 3 Comments. Parenchyma, collenchyma and sclerenchyma are three types of simple tissues. 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. Also, see Tissues Class 9 Notes, Video Explanation and Question Answers. Plants and animals are made up of many different kinds of tissues. Answer. Complex tissues are made of more than one type of cells that work together as a unit. 3. The sclerenchymatous cells do not have such thickenings. The cells of collenchyma are living and have the cytoplasm and the nucleus. What are Tissues? Chapter-wise NCERT Solutions For Class 9 Science Chapter 6 Tissues (Biology) solved by Expert Teachers as per NCERT (CBSE) Book guidelines. Collenchyma Sclerenchyma 1. 1) Tissues :- Tissue is a group of cells having similar structure and function. For example, groups of bone cells form bone tissues and muscle cells form muscle tissue. They are generally found below epidermis of dicot stem and petiole. State its function. Permanent tissues are derived from meristematic tissue once they lose the ability to divide. 2. They do not have the cytoplasm and the nucleus. Mention the most abundant muscular tissue found in our body. The tissues are dead which makes the plant hard and stiff (eg.
