Re:

The apical bud is growing. So lateral growth wont start, the apical bud will probaby just bend due to the circular shape of the petri dish? Also what other aspects of the plant growth and development that are regulated by auxin ? In your response, you MUST include how its action would differ for di...

hmm what happens if auxin promotes apical dominance, then it cant grow anymore due to the limiting space?

Re:

JackBean wrote:Hypothesis why or how?

The biomolecular reason here was the auxin and PIN proteins :)


Damn, idk about PIN proteins yet , but could you explain auxin and how it effects it? and maybe phototropism and geotropism?

Re:

OK, so the West, East, North and South are only for confusion... Yep, in such case you're researching the effect of gravity. And yes, auxin flux is responsible for that. could you suggest me a possible hypothesis? And also... Suggest a biomolecular reason for any diffrences observed in the growth o...

Its facing upright, so vertical


like standing up , your head is the N, your arms are E and W and your feet are S. sorta like that

Re:

And how does gravity differ depending on whether is the seed facing toward North or West? Sorry, I don't have Skype or anything Well just imagine it will be like >N W E >S and in each of the poles, there are 2 seeds in them

Re:

yeah, I understand that. Does the Petri dish stay as it is or is it turned to be vertical or upside-down? What's the aim of the experiment? The petri dish is just upright and left alone for 1 week. The aim is most likely to observe the growth reponse from seeds to light and gravity ? Got skype or s...

Re:

JackBean wrote:so did the seeds stay oriented to the two poles (there are no poles in East and West :roll:)? Or did you change it?


Like on the petri dish , imagine there are 4 points, N E S W. And in each of those directions we put 2 seeds in there. Btw, do you hhave any IM ?

Plant hormone experiment!

Got given a practice prac on plant hormones. Method: 1. Place 8 corn seeds (with 2 each facing towards the 4 poles, so North, East, South, West). 2. Cover seeds with a piece of filter paper 3. Pack petri dish with moist cotton wool. 4. Put lid on the petri dish and seal it with sticky tape. 5. Stand...

why the orientation of a protein in the plasma membrane?

Have no idea, thanks appreciated !!
