TISSUE

Lesson plan:  Class 9

Tissue engineering is fast becoming a market with huge potential, addressing specific medical needs such as organ failure or major tissue damage. It enables tissue regeneration where evolution prohibits natural regeneration. In short, tissue engineering allows the body to heal itself. Regeneration means the re-growth of part of the affected or lost organs of the remaining tissue. Animals can regenerate some organs, such as the liver. If a part of the liver is lost due to illness or injury, the liver grows back to its original size, but not in its original form. Three general components are involved in tissue engineering: (1) reparative cells that can form a functional matrix; (2) an appropriate scaffold for transplantation and support; and (3) bio reactive molecules, such as cytokines and growth factors that will support and choreograph formation of the desired tissue.

  The SAMR Model is a framework created by Dr. Ruben Puentedura that categorizes four different degrees of classroom technology integration. The letters "SAMR" stand for Substitution, Augmentation, Modification, and Redefinition. The SAMR model is essentially a planning tool that helps to design better learning activities for students. The framework provides pedagogical insight into how technology can and should be used in the classroom.

The 2030 Agenda for Sustainable Development is universal, holistic and indivisible, with a special imperative to leave no one behind. The achievement of SDG 4 – ensure inclusive and equitable quality education and promote lifelong learning opportunities for all – plays a central role in building sustainable, inclusive and resilient societies. Progress has been made towards achieving SDG4, and there are new knowledge horizons and opportunities for strengthened solidarity and partnerships around the provision of quality education and lifelong learning for all. Yet the context is also changing with new technologies and skill demands, as well as economic shocks and environmental degradation. Many barriers to education access and educational outcomes remain in place and challenges to the monitoring of progress remain. Since education is not only an integral part of, but also a key enabler for sustainable development, it needs to be included in national development plans and strategies for a

What are tissues? The definition of tissue in animals is a group of cells combined together to perform a certain function. There are four tissue types in animals, each type of tissue has its distinct structure and function. They are (1) epithelial tissues, (2) connective tissues, (3) muscular tissues, and (4) nervous tissues. Each of these tissues has its own unique structure and biological function. These different types of tissues are discussed below:

TISSUE What is tissue in the body? The body tissue is an aggregation of cells that function together and have a similar function. The cells of a multicellular organism do not usually function independently instead they are usually associated with other cells forming a tissue. Mostly, tissues are made up of several types of cells that cover different requirements of the tissue function. The study of tissues is called histology. This science studies the anatomy of different tissues using microscopes. The microscopic biological science histology helped in the classification of tissues of both plant and animal tissue as well as identifying their detailed structure.
