In this type, the first mitotic division is followed by cytokinesis resulting in the formation of two unequal cells. Subsequent divisions are of the free nuclear type making the endosperm cellular after cytokinesis or at maturit..

(x + a)(x + b)(x + c)(x + d) = 0 In such equations, if the sum of any two constants a, b, c, d is equal to sum of the other two, then such pairs are multiplied and solve them if a+b = c+d = m then, Now put x 2 + mx = t then, (t + ab)(t + cd) + k = 0. This can be solved..

Solution is defined as a homogeneous mixture of two or more chemical substances. The state of matter of a solution may be solid, liquid or gas. For example: common salt in water (liquid solution), air (gaseous solution), alloys (solid solution), et..
