Welcome to our new topic: CELLS

We have already learnt that there are multicellular and unicellular organisms. That is to say, that some living organisms are made of one cell and others of more than one cell. So….what is a cell?

1- Read the text 2.1 “Cell structure and organisation”, page 15 and solve exercise 1.

2- Search in the web pictures where examples of structures named in the exercise above are shown. (stomach,tissue,body system, organs, organism, cell, root). Add them in a new post in your blog. Remember to label the pictures and write down the meaning of each word.
