Practice more on Tissues. Question 10: Name the following: Tissue that forms the inner lining of our mouth. They are loosely packed and have large intercellular space (space between the cells). Sclerenchyma tissue can define as one of the types of ground or simple permanent tissue that constitutes both primary and stiff secondary wall. Question 7 Name two types of permanent tissue? They are different from animal tissues since there are several differences between the animal and plant cell. Your email address will not be published. Parenchyma, collenchyma and sclerenchyma are the examples of simple plant tissue whereas xylem and phloem are complex tissue. Fibres are elongated sclerenchymatous cells, usually with pointed ends. These are the cells that form the entire nervous system. Tissues: These are the cluster of structurally and functionally similar cells arranged and designed. How are simple tissues different from complex tissues? We can find them in places like alimentary canal and blood vessels. The cells are loosely packed. This is because the dividing tissue also known as meristematic tissue are present in specific regions only. These tissues help in connecting different parts of the body. Answer 1 (b) Question 2. Ans. Chapter-6. Delhi - 110058. Class- IX-CBSE-Science Tissues. Permanent tissues are the plant tissues that have lost the ability to grow and divide. Ø They have thick secondary cell wall. Define tissue. The sclerenchymatous cells do not have such thickenings. Sclerenchyma has a characteristic feature, where it functions to promote cell strength and conduction instead of being a dead cell. Animal tissues Parenchyma definition, the fundamental tissue of plants, composed of thin-walled cells able to divide. Complex tissues are made of more than one type of cells. They do not contain chlorophyll in any condition as they are dead cells. Q 4. Name them. The cells are dead. Question 3 Write down the functions of collenchyma? There is little space between cell. 1.
