Answer

To answer the question regarding the classification of flower organs, we need to analyze the parts of a flower and their functions.

### Step-by-Step Solution:

1. **Identify the Flower Parts:**
- The flower consists of several parts, including the calyx, corolla, androecium, and gynoecium.
- The calyx is made up of sepals, and the corolla is made up of petals.

2. **Classify Calyx and Corolla:**
- The calyx and corolla are located on the outer part of the flower.
- They serve primarily protective and aesthetic functions, helping to attract pollinators.
- Therefore, calyx and corolla are classified as **accessory organs**.

3. **Classify Androecium and Gynoecium:**
- The androecium consists of stamens, which produce pollen, and the gynoecium consists of carpels, which contain the ovary and stigma.
- These parts are involved in the reproductive process of the flower.
- Hence, androecium and gynoecium are classified as **reproductive organs**.

4. **Fill in the Blanks:**
- Based on the classifications:
- (a) **accessory**
- (b) **reproductive**

### Final Answer:
Calyx and corolla are (a) **accessory** organs while androecium and gynoecium are (b) **reproductive** organs.
