<p>auxins, gibberellins, etc...</p>

<p>General idea. You'll usually only see auxin or something.</p>

3

<p>well on the May SAT II bio, there was a set of questions that went with this experiment that dealt with auxins (I think). Know them in general, although if you have time, knowing them completely is even better.</p>

<p>And by the way, if you get a question on the AP BIO exam/ SAT II that gives you a list of plant hormones, the answer is almost always 'auxins'.</p>

yea pretty much i agree, Auxin is like the master of hormones it does pretty much everything and like 90% of the hormone questions usually have that answerr, the other 9% is if the question asks about "ripining" then the answer would be Ethynle (SP).....and the other 1% is the one thatnever happens</p>

<p>the ethenyl (sp) hormone is for aging because there is an "e" in the front like "elder". thats how i remember it!</p>

<p>you probably need to know all of the "tropisms" like geotropism, thigmotropism, phototropism and what it means for them to be positive/negative</p>

6

<p>Does GeoTropism= Gravitropism?</p>

7

<p>"GeoTropism= Gravitropism?"
yea if thats wat u wanna call it, but its known as geotropsim
(Theres also , Hydrotropism,Thigmotropsim, and phototropsim)</p>

<p>Thanks. 1o charzzz</p>

9

<p>np....let me know if u need anything else (with bio) PM me or something...</p>

10

<p>what the heck is ethenyl
ethanol is alcohol made anaerobically by yeast cells
ethylene is a plant hormone</p>

11

<p>what DOES it mean for the "tropisms" to be positive or negative? thanks</p>

12

<p>positive = Towards the Effect (Towards Light/Gravity/Water, Etc..)
Negative= Away from the effect ( Away from light, Water, Gravity,Etc..)</p>

<p>i believe that most of the time thought ,tropsims will be positive (not sure)</p>

13

<p>yeah, they're usually positive.</p>

<p>xylem, did you take the May SAT BIO? ahh, the results come out tomorrow!</p>

14

<p>good luck you guys</p>

15

16

<p>i guess the name xylem makes you seem like a veteran of biology</p>

17

<p>lol...yea plants' are my thing..lol (we ll at least structure)</p>

18

<p>definitely know tropisms</p>
