What is the primary aim of plant biotechnology?

The primary aim of plant biotechnology is to enhance crop yields and resistance to diseases. This field focuses on using molecular biology techniques, such as genetic engineering and genomics, to develop plant varieties that can withstand biotic stress (like pests and diseases) and abiotic stress (such as drought and salinity). By improving these traits, plant biotechnology helps ensure food security, increase the efficiency of agricultural production, and supports sustainable farming practices.

Enhancing crop yields means that farmers can produce more food using the same or fewer resources, which is essential in a world where the population is constantly rising. Resistance to diseases reduces the reliance on pesticides, which can have environmental and economic benefits. Overall, plant biotechnology aims to create resilient crops that are better suited to the challenges posed by climate change and agricultural demands.

The other options, such as decreasing crop prices, eliminating the need for fertilizers, or promoting farmers' markets, do not directly represent the fundamental goals of plant biotechnology. While these may be associated outcomes or aspirations within the broader agricultural landscape, they do not encapsulate the primary focus of enhancing crop performance through biotechnological innovations.
