CLASS 9A SCIENCE

Hello Learners, In the previous blog, we have discussed about simple permanent tissues. We learned about the structure, location and function of Parenchyma, Collenchyma and sclerenchyma. We have also learned about the diversity of epidermis of leaves. Today, we will discuss more about Complex Permanent Tissue of PLANT TISSUES. At the end of today's topic, learners will be able to  (i) define complex permanent tissue. (ii) explain the importance of complex permanent   tissue in the plant body. (iii) tell the location of complex  permanent  tissue in the plant body. (iv) draw the location of complex  permanent tis sue in the plant body. Important Instruction: Today, we will be completing the topic PLANT TISSUE. Kindly prepare well for google assessment scheduled as per information given below: Date:  02.05.2020, Saturday, Day 5 Period 7 Time 20 minutes There will be regular class in period 6. So, let us start the topic..... Revisit this ...

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. (v) explain the diversity in epidermis layer. So, let us start our topic for today............ Permanent Tissues The cells which are differentiated to perform a specific function and have lost the ability to divide are called permanent tissues. This pro...

Hello Learners, In previous blog, we learned about the significance of division of labour in multicellular organisms. The structural organisation of organs and organ systems is far more specialised and localised in complex animals than even in very complex plants. This fundamental difference reflects the different modes of life pursued these two major groups of organism particularly in their different feeding method. They are differently adapted for sedentary existence on one hand (plants) and active locomotion (animals) contributing to this difference in organ system design.  Today, we will discuss more about PLANT TISSUES. At the end of today's topic, learners will be able to  (i) define meristematic tissue. (ii) explain the importance of meristematic tissue in the plant body. (iii) tell the location of meristematic tissue in the plant body. (iv) draw the location of meristematic tissue in the plant body.               ...
