Question

Parasites which can grow saprotrophically in the absence of hosts are :

• A. Facultative saprophytes
• B. Obligate saprophytes
• C. Obligate parasites
• D. Facultative parasites

Answer 1

The correct option is A Facultative saprophytes

Option A is correct.

Parasites which can grow saprobiotically in the absence of hosts are facultative saprophytes. This is because a facultative parasite is cultivable on a dead medium i.e., in the absence of a host. It has parasitic potentialities. Saprophyte feeds on a decomposing matter from dead. Therefore, it is known as facultative saprophytes as both are cultivable on dead medium.
