Monocot and Dicot leaves were obtained, cleaned and observed under Microscope and Foldscope. It can be seen that the venation pattern in monocots run parallel whereas in dicots they are reticulate.

Observation of Monocot and Dicot Leaf Veins

Methodology of the experiments carried out:
 


 
 Observation of the pollen from the Hibiscus and Yellow Tabebuia flowers:
 
 
 The
 
 
 pollen is a powdery substance containing the pollen grains and
 
 are
 
 present on the anther of a flower. The pollen grains were examined as follows:
 

<ol>
 <li>
 The anther of the flower was removed and was placed on the centre of the glass slide containing a drop of water. The anther was gently squeezed with the help of a mounting needle and forceps.
 </li>
 <li>
 A coverslip was placed over the specimen and any excess water was removed using a blotting paper. The sides of the coverslip were attached to the microscopic slide with an adhesive tape.
 </li>
 <li>
 The glass slide was placed in the foldscope and the pollen grains were observed. The foldscope containing the glass slide was placed on the stage of the compound microscope and was observed using the microscope’s 10 X objective lens.
 </li>
</ol>
