Investigation into the effect of varying concentrations of potassium nitrate solution, on the germination and subsequent root radicle growth of cress seeds. The following investigation is based on seed germination and growth. In this particular study seeds will be subjected to a variety of different solution concentrations, the aim being to find out how this affects their growth and germination. Introduction The germination of seeds is dependent on the presence of three things; a sufficient water supply, a suitable temperature and an appropriate partial pressure of oxygen. Germination also relies on the maturity of the embryo as well as the presence of the three factors listed above. The picture above shows a seed in trans-section. The embryo consists of a shoot (plumule,) a root (radicle) and 1 or 2 seed leaves. The seed's food store is either contained in the endosperm (tissues surrounding embryo) or within the seed leaves. The role...
