Was the answer "fats" or "Water" in biology paper 1 ?

Also the question of the arrows was tricky ..

Raed:
i think it was fats cuz fats cnnot be found in plants!

nid404:
Green plants can make all the materials(including fats and sucrose)using water,carbon dioxide and salts. They r synthesized from sugar molecules and other molecules produced in photosynthesis.

Glucose and amino acids are transported in solution(water). Fats are synthesized for cell membrane and for storing in seeds.


SO THEY LACK FATS

Ukhti-R:
for sum reason.. I chose water... cuz a phloem tube transports amino acids and sucrose, and the aphid only fed on phloem tubes.... and why would a Aphid even need fats?

thukon:
The question was what do aphids LACK in their diet. Thats fats, because the phloem doesnt transport fats.
