Usually a single layer of closely-packed cells, epidermal tissue covers leaves and young stems and roots of vascular plants. Most epidermal cells secrete waxy substances which form a cuticle, or waterproof covering, over the aerial surfaces of the plant, such as the stems and leaves. The cuticle also resists viral, bacterial, and fungal invasion.
Because it lies in international waters, no single nation is responsible for its creation, and filtering out all the plastic will also remove plankton.
Therefore, all of the above
