Answer:
PP = 25%
Pp = 50%
pp = 25%
Explanation:
Using punnett square, we can predict the percentage probability of genotypes.
P p
P PP Pp
p Pp pp
In this cross we have,
PP = 1/4 = 25%
Pp = 2/4 = 50%
pp = 1/4 = 25%
We have ratio,
1 : 2 : 1
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.
