Which property of the pigment is responsible for its ability to initiate the process of photosynthesis ? Why is the rate of photosynthesis higher in the red and blue regions of the spectrum of light ?

Explanation

### Step-by-Step Solution:

1. **Identify the Pigment Involved**: The primary pigment responsible for initiating photosynthesis in higher plants is chlorophyll.

2. **Property of Chlorophyll**: Chlorophyll has the property of excitability. This means that when chlorophyll absorbs light, it can become excited and release electrons. This property is crucial because it allows chlorophyll to participate in the light-dependent reactions of photosynthesis.

3. **Electron Transfer**: When chlorophyll absorbs light energy, it becomes excited and emits electrons. These electrons are then replaced by electrons generated from the splitting of water molecules (a process known as photolysis). This electron transfer is essential for the continuation of the photosynthetic process.
