Tropisms for IGCSE Biology

[@anushaschutz8397]

Thank you so much for all you Igcse videos, they have helped me incredibly! Most of my knowledge of Biology is from your videos, because books can sometimes be quite long winded and often a bit intimidating at times but your vids can keep me interested for hours. Is there any chance you could make some more as it is the only way learn? :)

Thank you very much for uploading all these videos, they really help to clear up any confusion about a topic and are really well explained. I have my Biology exam next Tuesday (4/11/2014), and these videos are a brilliant source of revision. Thank you and keep going, they will really help others in my position!

So i had my mcq and theory today and all i can say is your video's have been extremely helpful and reliable. I'm glad i found this channel, so cheers Tom. If we ever meet the pint is on me sir. Thank you again.

Your video's are both entertaining and informative! Wish you we're my teacher back in high school, that guy was a boring old geezer. Cheers Tom!

Question about positive phototropisms in shoots: If the auxin collects on the dark side of the leaf and causes it to bend towards the light, wouldn't that cause what was the lights side to then become shaded by the bent over leaf and therefore become dark? And if that happens, would the auxin then collect there and cause the plant to bend back the other way which would then make it the bright side again and cause the whole process to repeat? If the above does happen, then why aren't plants zig-zagged in shape, and if that doesn't happen, why doesn't it?

+William Bezodis the process is slow enough to avoid this happening.
