(A) Growth in plants and Growth in Animals:
Growth in plants:
1.Plants grow faster and continuously throughout their life span.
Growth in Animals:
1.Animals grow slowly and after reaching certain size and age, animals stop growing.
(B) Growth in unicellular organisms and growth in multicellular organisms:
Growth in unicellular organisms:
1.Growth - can be observed in only in vitro cultures
Growth in multicellular organisms:
1.Growth can be easily observed in in vitro as well as in in vivo.
© Catabolism and anabolism :
Catabolism:
1.The biochemical reactions which are concerned with break down of complex organic substances into simple substances are collectively called Catabolism. E.g.,respiration.
Anabolism :
1.The biochemical reactions which are concerned with the synthesis of complex substances from simple substances are collectively called Anabolism.E.g.,Photosynthesis.
