Answer:
The DNA is a double helix or made up of two strands. The strands are separated during replication, each serving as a template to produce a complementary strand of each of the separated single strands. Therefore after replication, two double stranded DNA molecules will be present.
The genotype depends if the purple flower is heterozygous dominant of homozygous dominant. But the total possible phenotypes available is 2, purple or red.
The photosystems are sets of chlorophyll molecules and other pigments and transmembrane proteins packed in the thylakoids, the transfer of electrons from the primary electron acceptor of photosystem II to the P700 chlorophyll a molecules of photosystem I is called photophosphorylation.
<h3>What is photophosphorylation?</h3>
It is the global process of transformation of the energy stored in the electron of the reactive center excited by light, in a pyrophosphate bond of an ADP molecule.
When a photon is absorbed by one of the pigments of photosystem II, it quickly bounces off the other molecules until it reaches chlorophyll a in the reaction center.
The electron, after leaving photosystem II, reaches the reaction center of photosystem I, where chlorophyll P700 is, the pigments absorb light and the electron reacquires a high level of energy.
Therefore, we can conclude that when this molecule absorbs light energy, an electron is thrown up to a higher energy level and transferred to another molecule, a primary electron acceptor.
