This is the last topic that has been taught by Dr.
Parameswari. In this topic, we have been introduced five main types of hormones
which are auxin, cytokinin, gibberellins, abscisic acid and ethylene. Auxin is
a plant hormone which causes the elongation of cells in shoots and is involved
in regulating plant growth. Cytokinins are a class of plant growth substances
that promote cell division. Next, gibberellins are plant growth hormones that
regulate growth and influence various developmental processes, including stem
elongation, germination, dormancy, flowering, sex expression, enzyme induction
and leaf and fruit senescence. For abscisic acid, it helps in promoting bud
dormancy and the last one is ethylene. Ethylene is the only hormone forms in
gas and it controls fruit ripening, flower wilting and leaf falls. These are
the simple points that I got from this topic.
I have doing a quiz about this topic and I really sad because I got a lower marks. It just a simple question about all these hormones and straight forward questions but I cannot answer it!!! This is all because I did not read the notes first.. hmm..
