A group of students have carried out an experiment to investigate the relationship between the amount of growth hormone BAP in the culture medium and the growth of shoot.They have supplemented the medium with 4 different concentration of growth hormone which is (1 mg/L ,2 mg/L BAP,3 mg/L 4 mg/L) of BAP.According to the result after eight weeks, BAP at 2 mg/L had given better response with respect to shoot induction, shoot multiplication, length of shoot, and number of leaves per explants when compare with other amount of BAP.  Discuss why?

Select two (2) seed propagated plants of your choice and discuss how you would practically precondition them to stimulate/enhance germination.

We know that short-day plants do not really need short days, but actually long nights. Describe the type of treatment that proves this. Is some kind of light given during the night or some period of darkness given during the day?

Tobacco plants invest a lot of resources into the production of secondary compounds know as alkaloids (e.g., nicotine) that we believe act as defenses against herbivores. The researchers did an experiment where they added a hormone that reduces the production of alkaloids. In graph (a), the data show that the hormone reduced the proportion of alkaloids as a function of leaf mass relative to controls- so the hormone worked. They also measured the lifetime seed production of the plants in both treatments without any herbivores present (b). They had the following results. What might you conclude/hypothesize/investigate based on the data in graph (b) (a) Chemical defenses (percent of leaf mass) 1.8% 1.4 1.0 0.6 0.2 No hormone added Hormone added (b) Lifetime seed mass (g/plant) -18 14 10 No hormone added Hormone added It would be good to test whether the hormone is very specific or whether it might also cause changes in other metabolic processes The hormone has no effect on the lifetime…
