a student conducts an experiment on decorative plants. He varies the type of fertilizers that been used for each pot, those are fertilizer A, B, and C. Data about plant height and number of flowers are recorded daily for 21 days. The independent variable of this experiment is ...

The table below shows data of an experiment about the effect of media on the growth of groundnut. Same volume of media are used. Each set of plant is watered with the same amount of water and same frequency. Data started to be recorded when the first plumule emerges. What can be concluded from this experiment?
groundnut stem elongation is inhibited by the presence of wet cotton
groundnut can only grow if being planted in soil
growth of groundnut is highly depend on the presence of water
growth of groundnut is faster if the seeds are planted in soil
growth of groundnut is not affected by wet cotton

which of the following is not a principle of plant development?
the presence of actively dividing cells in meristem makes plant able to develop continuously
plant tissue culture is an example of artificial reverse development in plant
development of plant is really flexible so that a cell can be a whole new plant
once a plant produces fruits, its development process stops
the final shape of a plant organ is determined by the rate of cell division in that part

a farmer has problem about how to keep his product, that is cut flowers, to stay fresh during shipment. what can you suggest to solve this problem?
he could try to spray artificial auxin to prolong the freshness
he could try to infuse the flower with solution of gibberellin
he could try to put the flowers in tubes containing ethylene
he could try to apply cytokinin to prolong the freshness
he could try to inject a proper amount of ABA to the flowers

A gardener wants to have her decorative plant becomes shady and leafy, not only growing upward. What can you suggest to her?
spray the leaves with cytokinin so it can widen the size of leaves
inject the stem with artificial gibberellin so it can breaks dormancy
water the plant with auxin solution to promote primary growth
cut the upper part of the shoot in order to minimize the apical dominance
apply abscissic acid to promote abscission of leaf, flower, and fruit
