Process Involved in Photosynthesis
The correct answer is option B - Free energy is converted into potential energy and stored.
Photosynthesis is a process in which green plants, algae, and some bacteria convert light energy from the sun into chemical energy in the form of glucose. This process involves several steps, which can be divided into two stages:
1. Light-dependent reactions
2. Light-independent reactions
Light-dependent reactions
These reactions occur in the thylakoid membranes of chloroplasts and require light energy to proceed. The energy from light is absorbed by chlorophyll and other pigments, which then transfer the energy to other molecules in the thylakoid membrane. This process generates ATP and NADPH, which are used in the second stage of photosynthesis.
Light-independent reactions
These reactions occur in the stroma of the chloroplasts and do not require light energy to proceed. In this stage, carbon dioxide is fixed into glucose using ATP and NADPH generated in the first stage. This process is also called the Calvin cycle.
The process of photosynthesis can be summarized as follows:
- Light energy is absorbed by chlorophyll and other pigments in the thylakoid membrane.
- This energy is transferred to other molecules in the thylakoid membrane, generating ATP and NADPH.
- Carbon dioxide is fixed into glucose using ATP and NADPH in the stroma of the chloroplasts.
In summary, photosynthesis involves the conversion of light energy into chemical energy, which is stored in the form of glucose. This process is essential for the survival of plants and other organisms that depend on them for food.

Which one of the following is the process involved in photosynthesis?a...
- For plants to perform photosynthesis they require light energy from the sun, water and carbon dioxide.
- Water is absorbed from the soil into the cells of roots. The water passes from the root system to the xylem vessels in the stem until it reaches the leaves.
- Carbon dioxide is absorbed from the atmosphere through pores in the leaves called stomata. The leaves also contain chloroplasts which hold chlorophyll. The sun’s energy is captured by the chlorophyll.
