29. List five main groups of natural plant growth regulators.
Answers
Answer:
(I) ER :It is used to synthesise protein and lipid and to store calcium.
(2) Golgi Apparatus : It is used to packaging and secretions of proteins.
(3) Chloroplast :It is used in synthesise food by process of photosynthesis.
(4) Lysosome: It is used in break down excess

(2) Golgi Apparatus : It is used to packaging and secretions of proteins.
(3) Chloroplast :It is used in synthesise food by process of photosynthesis.
(4) Lysosome: It is used in break down excessor worn-out cell parts. They may be used to destroy invading viruses and bacteria.
(5)Ribosomes:Ribosomes have two main functions — decoding the message and the formation of peptide bonds
