Question

Which branch of botany is concerned with the study of photosynthesis?
A.Ecology
B.Psychology
C.Plant physiology
D.Embryology

Answer 1

Hint: The branch of botany that is concerned with the study of photosynthesis is plant physiology as it is concerned with the functioning of the plant.

Complete answer:
The natural science that deals with the study of plants are botany, the branch of botany that studies the function of photosynthesis is Plant Physiology as this branch studies the vital activities of plant and all the chemical and physical changes that occurs in a plant cell and if there is the exchange of substance between the cell and the environment. Ecology deals with the study of the relationship between the living organisms and the environment, psychology is the study of mind and the behavior of a person it includes many sub-fields, embryology is the study of the development of gametes, fertilization and the development of the fetus and embryo.
Photosynthesis is a process of conversion of inorganic of carbon to organic form. It consists of two reactions -Light reaction and dark reaction. Light reaction also known as energy transduction reaction in which ATP and NADPH is formed while in dark reaction this ATP is used to fix the inorganic form of carbon with the help of the enzyme RuBisCo.

Hence, the correct option is ‘C’.

Note:
 Plant physiology mainly defines the functions of the photosynthesis, respiration, plant hormone functions, plant nutrition, tropisms in a plant, nastic movements that are caused in plants, photoperiodism, photomorphogenesis, etc.
