Spores are the reproductive unit produced as a result of sexual reproduction and asexual reproduction in both lower and higher plants.

The plant groups like Fungi, Algae, Bryophytes, Pteridophytes and Gymnosperms produce these spores which provides adaptation as they can be dispersed for the long-distance as well as germinate and form an organism.

When a molecule absorbs a photon, one of its electrons is raised to the ______ state.
77julia77 [94]

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.
