(A) Definition of biological species was given by Ernst Mayr. - This statement is correct. Ernst Mayr is indeed famous for his contributions to the biological species concept, which defines a species as a group of individuals that actually or potentially interbreed in nature.
(B) Photoperiod does not affect reproduction in plants. - This statement is incorrect. Photoperiod, or the length of day and night, significantly affects reproduction in many plants. It influences flowering time, which is a critical part of the reproductive process in plants.
(C) Binomial nomenclature system was given by R.H. Whittaker. - This statement is incorrect. The binomial nomenclature system was introduced by Carl Linnaeus, not R.H. Whittaker. R.H. Whittaker is known for proposing the five-kingdom classification system.
(D) In unicellular organisms, reproduction is synonymous with growth. - This statement is correct. In unicellular organisms, reproduction through cell division is essentially a form of growth, as one cell divides to become two, increasing the population size.
Therefore, the two correct statements are A (Definition of biological species was given by Ernst Mayr) and D (In unicellular organisms, reproduction is synonymous with growth), making the correct answer: A and D

Explanation:
(A) Definition of biological species was given by Ernst Mayr. - This statement is correct. Ernst Mayr, a German-American biologist, proposed the Biological Species Concept in 1942, which defines a species as a group of interbreeding populations that are reproductively isolated from other such groups.
(B) Photoperiod does not affect reproduction in plants. - This statement is incorrect. Photoperiod, or the duration of light and darkness, affects many aspects of plant growth and development, including reproduction. Some plants require specific photoperiods to initiate flowering, while others may require a specific photoperiod to prevent flowering.
(C) Binomial nomenclature system was given by R.H. Whittaker. - This statement is incorrect. The binomial nomenclature system, which assigns a two-part name to each species, was developed by Carolus Linnaeus, an 18th-century Swedish botanist and zoologist.
(D) In unicellular organisms, reproduction is synonymous with growth. - This statement is correct. Unicellular organisms, such as bacteria and protozoa, reproduce asexually by cell division, which results in an increase in the number of cells and overall growth of the organism. In these organisms, reproduction and growth are essentially the same process.
Therefore, the two correct statements are (A) and (D).
