First thing that I can't really get is that have they managed to cut the shoot into two and then placed agar and metal or have they made a hole and passed a shoot through it lol :D.
If they've cut it, they I think the one with agar jelly and the untouched shoot should show tropism. How??? I don't feel right choosing metal lol :D...

LOL ... This is what I can't understand too. Anyway, apparently the explanation is :: The sugar agar allows the auxin to pass through as it is organic and the metal doesn't.

Guys just one thing, in the circulatory system what is an artery??? I mean an organ, tissue etc. And is blood actually a tissue here??? (LOL my understanding of tissues is limited to colony of cells :D)...

Umm, M/J 2000, P1, Q 27.
How is the answer D?
Shouldn't it be C, because the foliage leaves have begun to develop, and as soon as they do, photosynthesis starts, thus increasing the mass.
Though there is also a possibility that the production and usage is at equilibrium, because they plant is still growing, so the is making use of the resources?
But, point is, the increase should start as leaves have formed, and that is C.
???

Arteries and veins are BLOOD VESSELS
Blood cannot be a tissue, though it may have RBCs or WBCs, collection if cells as you say.. they don't really "join up" to do specific tasks. Let's just say the blood is a mixture of cells, ions etc. etc.
