TISSUES.

 a, a single flower. 



As we are going to 

 talk about tissues, 

 I shall begin by- 

 asking you to tell 

 me what a tissue 

 is (p. 167). 



(i) So now we will 

 take a tissue of 

 the simplest form- 

 some cells joined 

 only end to end. 

 You will find ex- 

 amples in many 

 hairs. If you look 

 again at Fig. 54, 

 p. 8 1, you will see 

 some hairs magni- 

 fied, which are made 

 up of cells joined 

 only end to end.
