#aerenchyma
- Actinenchyma — A structural plant parenchymal tissue, characterized by star-shaped cells with large radiating extensions that leave voluminous intercellular air spaces (lacunae) between them. This special type of tissue is specific to aquatic and marsh plants, having the primary physiological role of facilitating gas circulation and ensuring the buoyancy and respiration of submerged organs in oxygen-deficient environments.
- Aerenchyma — A fundamental parenchymal plant tissue structurally characterized by the presence of large intercellular spaces, lacunae, or air-filled channels. It is specific to aquatic (hydrophytic) and marsh plants, playing the vital role of ensuring oxygen and gas circulation to submerged organs and facilitating the buoyancy of aerial parts.
