1.	Give scientific reasons:Cotton fabrics, gunny bags, leather items and wooden items do not last long.
Answer» Microscopic spores of fungi are present in the air. If there is sufficient moisture, spores germinate on cotton fabric, gunny bags, leather, wooden items etc. The fungal hyphae (fibres of the fungus) penetrate deep into the material to obtain nutrition and to reproduce. This causes the materials to wear and become weak. As a result, cotton fabric, gunny bags, leather and wooden items do not last long.
