Q4. Matching the words given in 2 columns
Match the names of the organelles given in column 1 with the functions given in column 2 choose the answer which gives the correct matching of the alphabets of the two columns.
Organelles  Functions  
A  Golgi bodies  P  Photosynthesis 
B  Ribosomes  Q  Secretion 
C  Chromoplasts  R  Respiration 
D  Mitochondria  S  Protein synthesis 
T  Cell destruction 
1.A = Q  B = P  C = S  D = R 
2.A = R  B = P  C = S  D = Q 
3.A = Q  B = S  C = P  D = R 
4.A = T  B = S  C = P  D = Q 
Answer:3
