Light-independent reactions of photosynthesis occur in thylakoids/stroma of chloroplast.

Explanation

**Step-by-Step Solution:**

1. **Understanding Photosynthesis**: Photosynthesis is the process by which green plants, algae, and some bacteria convert light energy into chemical energy, producing their own food. This process primarily occurs in chloroplasts, which contain chlorophyll.

2. **Types of Reactions in Photosynthesis**: Photosynthesis consists of two main types of reactions:
- **Light-dependent reactions**: These reactions require light and occur in the thylakoids of the chloroplasts. During these reactions, light energy is converted into chemical energy in the form of ATP and NADPH.
- **Light-independent reactions (Calvin Cycle)**: Also known as dark reactions, these do not require light directly and occur in the stroma of the chloroplasts. They use the ATP and NADPH produced in the light-dependent reactions to synthesize glucose from carbon dioxide.
