What is forster transfer ?

Explanation

### Step-by-Step Solution:

1. **Definition of Förster Transfer**: Förster transfer, also known as Förster resonance energy transfer (FRET), is a physical phenomenon that occurs in the context of photosynthesis. It refers to the transfer of energy between excited molecules, particularly pigments, in plants.

2. **Excitation of Pigments**: When sunlight hits the pigments in plant cells, the energy from the light excites the electrons in these pigments. This excitation causes the molecules to enter a higher energy state.

3. **Energy Transfer Between Pigments**: Once the pigments are excited, the energy can be transferred from one pigment molecule to another. This transfer occurs without the movement of the molecules themselves, hence the term "resonance."
