The wild varieties of plants prefer to have thorns, spines, fibres and bitterness. Why?

Explanation

### Step-by-Step Solution

1. **Understanding Wild Varieties**: Wild varieties of plants have evolved over time to adapt to their natural environments. They possess certain traits that help them survive against various biotic and abiotic stresses.

2. **Defensive Mechanisms**: The presence of thorns, spines, and bitterness in wild plants serves as a defense mechanism against herbivores. These features deter animals from eating the plants, thus enhancing their chances of survival and reproduction.

3. **Competition for Resources**: In the wild, plants compete for sunlight, water, and nutrients. Features like thorns and spines can help reduce competition by making it difficult for other plants or animals to access them.
