Suggest some of the features of plants that will prevent insect and pest infestation.

2. **Rendering Flowers Nectarless**:
- Another feature is to render the flowers nectarless. Many insects are attracted to flowers for their nectar. By eliminating nectar production, plants can reduce the attraction of pollinators that may also serve as pests.
