Question

how sclerenchyma tissues are important for plant though they are dead tissue?​

Answer 1

Sclerenchyma cells are strong, thick cells that provide most of the support in a plant. They are known to have extremely thick cell walls and do not participate in many of the other activities of the developing plant, such as photosynthesis, because their focus is strictly on support and structure.
