A flower of tomato plant following the process of sexual reproduction produces 240 viable seeds. Answer the following questions giving reasons :
What is the minimum number of pollen grains that must have been involved in the pollination of its pistil?

Answer 1

The number of suitable seeds delivered by the tomato plant through sexual proliferation = 240

(a) The base number of dust grains that more likely than not been associated with the fertilization of its pistil are 240 in light of the fact that every dust grain contains two male gametes. Out of postulations two gametes, one circuit with polar cores and structures endosperm, while, the other male gamete wires with the egg cell to frame the zygote that in the long run offer ascent to seeds. Along these lines, so as to acquire 240 seeds, the number of dust grains required would be 240.
