Given below are two statements. Statement I - There is no need of agitation in callus culture however it is necessary in suspension culture. Statement II - During tissue culture techniques, the temperature of the lab is maintained between 18 to 20°C. In the light of above statements, select the correct option given below:

Step-by-step solution

Statement I is correct because callus culture is typically grown on a solid agar medium where agitation is not required. In contrast, suspension culture involves growing cells in a liquid medium, which requires continuous agitation (usually on a rotary shaker) to ensure proper aeration, nutrient mixing, and to prevent the aggregation of cells. Statement II is incorrect because the standard temperature maintained in a plant tissue culture laboratory is generally around 24^ C to 28^ C (often specified as 25 2^ C ), n
