MICROSCOPY. 
Part  1. — From  the  stem  given  you  for  study,  first  prepare  several  thin  trans- 
verse, longitudinal-radial  and  longitudinal-tangential  sections,  placing  some  of 
each  kind  in  water  and  the  rest  in  alcohol  until  required  for  use.  Then  pro- 
ceed to  the  study  of  the  sections,  applying  such  reagents  or  stains  as  are  neces- 
sary to  enable  you  to  answer  the  following  questions: 
(1)  Is  the  stem  that  of  a  fern,  that  of  a  monocotyl,  that  of  a  gymnosperm, 
or  that  of  a  dicotyl  ?  State  reasons  for  your  conclusion.  (2)  If  vasal  bundles 
are  present,  to  what  type  and  variety  do  they  belong  ?  (3)  What  lignified  tissues 
are  present  in  the  area  enclosed  by  the  cambium  zone  ?  (4)  What  lignified  tis- 
sues occur  in  the  area  exterior  to  the  cambium  zone  ?  (5)  What  layers  of  the 
bark  are  present  in  this  stem  ?  (6)  Of  how  many  rows  of  cells  are  the  medullary 
rays  composed  ?  (7)  Is  starch  present  ?  What  test  did  you  apply  to  determine  ? 
(8)  What  kinds  of  secretion-sacs,  if  any,  are  present  ?  (9)  Is  collenchyma  present  ? 
If  so,  in  what  part  of  the  stem  does  it  occur,  and  how  does  it  differ  from  paren- 
chyma? (10)  What  reagent  could  you  use  that  would  stain  the  cellulose  mem- 
branes blue  or  purple  and  the  lignified  and  cutinized  ones  brown  or  yellowish- 
brown  ?
