 (c) Xanthophyll  (d) Cytoplasm 
 Sol.54.(b)  Chlorophyll  -  Element  present 
 in  chlorophyll  is  magnesium.  Cytoplasm  - 
 The  ?uid  inside  the  cell.  It  functions  as  a 
 cellular  metabolism,  transport,  and 
 storage  medium  while  providing 
 structural  support  and  facilitating  signal 
 transduction  within  the  cell.  Cladophyll  - 
 Shoot  system  in  which  leaves  do  not 
 develop.  Xanthophylls  are  yellow 
 pigments  that  are  one  of  the  important 
 divisions of the carotenoid group.

 provide  food  ?  Herbivores  (goat)  ? 
 Carnivores  (tiger).  In  aquatic  ecosystems 
 Phytoplankton  get  energy  from  sunlight 
 and  provide  food  ?  zooplankton  ? 
 ?shes.

 ______. 
 SSC MTS 17/05/2023 (Morning) 
 (a) creepers  (b) transportation 
 (c) venation  (d) transpiration 
 Sol.59.(d)  Transpiration.  Three  types  of 
 Transpiration  :  Stomatal  transpiration  - 
 Evaporation  of  water  through  stomata. 
 Lenticular  Transpiration  -  Evaporation  of 
 water  through  lenticels  (small  minute 
 openings  present  on  the  stem),  Cuticular 
 Transpiration  -  Loss  of  water  from  the 
 cuticle  (waxy  layer  on  the  surface  of 
 leaves).
