Photosynthesis is .
a. divided into the steps of light dependent reactions, light independent reactions, and oxidative phosphorylation.
b. not a significant environmental process.
c. only found in certain specialized plants.
d. divided into two major steps, light dependent reactions and light independent reactions.
e. not dependent on sunlight at all.

d. divided into two major steps, light dependent reactions and light independent reactions

Explanation:

Photosynthesis is a chemical process by which plants make their own food in the presence of sunlight by utilising carbon dioxide (CO2) and water (H2O) and produces oxygen (O2) and energy.

The process of photosynthesis is divided in to two stages:  light dependent reactions and light independent reactions.

In light-dependent reactions, the enrgy from the sunlight i sabsorbed by chlorophyll and converted into chemical energy in the form of electron carrier molecules such as NADPH and ATP.  Photosystems I and II harness light energy, both of which are present in chloroplastic thylakoid membranes.  

light-independent reactions ustilises the chemical energy produced in light-dependent reactions and form Carbohydrate molecules from carbon dioxide.

Hence, the correct option is d.
