Explanation:

In February 2025, the Government of Tamil Nadu launched a cryogenic facility (cryogenic seed vault) to preserve endangered and rare plant species.

• The facility uses cryopreservation technology (around −196°C using liquid nitrogen)
• It is designed to conserve seeds, tissues, and genetic material of endangered plants
• It was established as part of biodiversity conservation efforts at institutions like Tamil Nadu Agricultural University (TNAU), Coimbatore
• Objective: Long-term preservation of plant genetic resources to prevent extinction

Tamil Nadu's Role in Plant Conservation

Based on recent environmental initiatives:

• The State government of Tamil Nadu is noted for launching advanced conservation projects.
• In February 2025, the state established a state-of-the-art cryogenic facility.
• The primary objective of this facility is the long-term preservation and protection of various endangered plant species found within the region and potentially beyond.
• This initiative highlights Tamil Nadu's commitment to biodiversity conservation and scientific approaches to environmental protection.

Therefore, the launch of this crucial cryogenic facility for preserving endangered flora is attributed to the Tamil Nadu government.
