Substrand: "7.7 Introduction to cells" (12 periods)

This sub-strand deal with living things which are made up of small parts called cells. We can see cells with the aid of microscope. Without a cell there is no life. In living things the cells are arranged in groups. These groups of cells are called tissues. Tissues do a particular job. Cells form into more cells by cell division. Collections of tissues in living things make an organ. Collection of organs makes system. A group of body system makes up an organism.
