Ans.
In flowering plants, the male reproductive part or stamen is made up of a stack-like structure, known as filament and an ovule-like structure, known as anther. In anthers, microsporangia are present that produce pollen through mitosis.
Thus, 'if anthers are removed from a flower, it will not be able to form seeds as seeds are developed from zygote, that forms by the fusion of male gamete (pollen) and female gamete (ovum).'
The correct answer is: D) excited
A molecule is in an excited state when its energy level is higher than the ground state. That molecule stays in excited state for short time and then returns to a state with lower energy. This return to a lower energy level is described as decay and is the inverse process of excitation.
The transition from ground to excited state of an atom is possible if electrons gain energy that is higher than the difference in energies between the two energy orbits.
