What are antenna molecules in photosnthesis ?

Explanation

**Step-by-Step Solution:**

1. **Definition of Antenna Molecules**: Antenna molecules, also known as light-harvesting complexes, are essential components of the photosynthetic process in plants. They are primarily made up of proteins and pigments, such as chlorophyll.

2. **Location**: These molecules are located within the thylakoid membranes of chloroplasts. Thylakoids are disc-shaped structures that are stacked together to form granum, which is where the light reactions of photosynthesis take place.

3. **Function**: The primary function of antenna molecules is to capture light energy from sunlight. They absorb photons and convert this light energy into chemical energy.
