Question

1. Complete the table below on the adaptations and functioning of some structures in a dicotyledonous stem.

   Part	Adaptation
   Cambium
   Parenchyma

2. Explain why the leaf of a sisal plant has a thick and shiny cuticle. 

Answer 1

1.  

   Part	Adaptation
   Cambium	(Small) cells with dense cytoplasm to enable rapid mitotic division/giving rise to secondary growth.
   Parenchyma	Have thin walls for faster passage of materials have large vacuole/irregular shape for storage/provide space for packing.

2.  
   1. (Sisal is a xerophyte) the thick cuticle enables it to conserve water; reduce water loss;
   2. It is shiny to reflect light, minimizing evaporation by radiation.
