if you only have limited time.. then you must have plants with same age and almost similar size... basically you can work on its physiology.. example effects of acid rain and its conc on the growth of plant ( you may make use of sulfuric acid) or may be what type of soil it will best grow.. hormonal...

effect of lead on photosynthesis and respiration

check out this site.. a good discussion is written here m or here it is. Photosynthesis: The process of photosynthesis is adversely affected by Pb toxicity. Plants exposed to Pb ions show a decline in photosynthetic rate which results from distorted chloroplast ultrastructure, restrained synthesis o...

Basically lead is not an essential element of plant, however it can easily be absorbed ( thats why there are the so called heavy metals on plants, w/c are toxic to humans when eaten). Small amount of lead may not have effect on its growth, however, greater concentration (its uptake is basically regu...

plant systematics

some of the chloroplast sequences use for molecular systematics are rbcl, matk, atpB, ITS and the trn spacers (trnT, trnF and trnL). these trn spacers are noncoding genes, aside from this description what else are the characteristics of these genes (trn spacers?)
