Mineral ion concentration in tissues that reduces the dry weight of tissues by about 10% is considered as

Answer: BSolution: In higher doses, micronutrients, become toxic. Mineral ion concentration in the tissues which reduces dry weight of tissues by 10% is called toxic concentration. Critical toxic concentration. Critical toxic concentration is different for different micronutrients as well as different plants. for example $M{n}^{2+}$ is toxic beyond 600 $\mu$ $g^{-1}$ for soybeam and beyond $5300\mu g$ $g^{-1}$ for sunflower toxic effects may be due to an excess of the micronutrient or its interference in the absorption and functioning of other nutrients.
