Which plant tissue remains in an active metabolic state always?

Meristematic tissue remains in a perpetually active metabolic state. Unlike permanent tissues that differentiate and often become metabolically less active or die, meristematic cells continuously divide and maintain high metabolic activity throughout the plant's life. These cells have dense cytoplasm, prominent nuclei, and lack vacuoles, all indicating their constant readiness for division and growth. This continuous activity enables plants to grow indefinitely, produce new organs, and regenerate damaged parts throughout their lifespan.
