for plant physiology, please answer the following questions
16) Pattern formation in any organism is a big deal. Where the endodermis forms in the root and where trichomes will not form on the leaf epidermis are both examples of A) Proteins produced in one cell and migrating to adjacent cells to control cell fate B) Auxin gradients created by PIN proteins and polar auxin transport to control cell fate C) Response regulators shuttling between the cytoplasm and nucleus to control gene expression D) The mutual antagonism of gibberellic acid and abscisic acid controlling cell fate E) Cell fate predetermined by cell lineages established during embryogenesis. 17) Strigolactone is a hormone that promotes branching. During the strigolactone signal transduction cascade, in the presence of strigolactone A) Histidine phosphor-transfer proteins shuttle into the nucleus to promote gene expression B) Cells in the immediate area of stimulation commit suicide in a hypersensitive response C) Vascular tissues develop is a process called "strigolactone canalization" D) Target proteins are tagged with ubiquitin and targeted to the proteosome for degradation. E Mobsters cut off the head of your prize race horse and leave it under your bedsheets for you to find when you wake up in the morning. 18) If you grow an apple tree from a seed, you likely will not get flowers or fruits for four to eight years because A) Vernalization is required B) A specific photoperiod is required C) A juvenile period must be passed through D) A suitable pollinator must be present E) A suitable period of cold temperature must be passed through. 19) Arabidopsis is a long day plant. This means that Arabidopsis A) seeds will germinate quickly during long days B) seeds will stay dormant during long days C) plants will flower during long days D) plants will propagate vegetative during long days E) plants will begin to senescence during long days thot is a tymial short day nlant and you are taskedExplanation / Answer
16. Option B is correct.
Development in living organisms involves both pattern formation and growth.
In plants, Auxin is the major phytohormone involved in the pattern formation.
17. Option D is correct.
Strigolactone signaling involves proteasomal degradation of target proteins.
18. Option C is correct.
A plant makes flowers only in its adult phase (After the completion of juvenile phase).
19. Option C is correct.
Arabidopsis is a long day plant which means that flowering is induced in the long day conditions.
