Hello Learners, In the previous blog, we have discussed about the growth of plants. We are aware that the growth of plants occurs only in certain specific regions. This is because the dividing tissue known as Meristematic tissue is located at these points. We have also discussed about different types of Meristematic tissues and its location. Today, we will discuss more about Permanent Tissue of PLANT TISSUES. At the end of today's topic, learners will be able to  (i) define permanent tissue. (ii) explain the importance of  permanent  tissue in the plant body. (iii) tell the location of  permanent  tissue in the plant body. (iv) draw the location of  permanent tis sue in the plant body.
