MCQ on Halophytes




Halophytes are plants adapted to thrive in high-salinity environments, like coastal areas or salt marshes. They possess specialized mechanisms to tolerate and even utilize salt, enabling them to grow, absorb water, and survive in saline conditions where most plants would perish. This is an MCQ on Halophytes: Adaptations and Examples.
