Answer:
Fungi most fungi produce cellulases.
Explanation:
Fungi are eukaryotic microorganisms, however unlike other eukaryotes. Their cell wall is made up of chitin instead of cellulose.
Chitin is a fibrous polysaccharide found in the exoskeleton of arthropods and the cell wall of fungi. where as cellulose is also a polysaccharide which is an important structural component of plant cell wall.
Since fungi are saprophytic they produce enzymes such as cellulases that will help in breakdown of cellulose for food.
They cannot have a cell wall made of cellulose.
Adaptations in humans can be physiological, genetic, or cultural, which allow people to live in a wide variety of climates. There has been a great deal of research done on developmental adjustment, acclimatization, and cultural practices, but less research on genetic adaptations to cold and heat temperatures.
