Answer
Classification — Classification is a system of arranging living organisms into groups based on their similarities and differences.
Binary fission — In a full-grown Amoeba, first the nucleus divides into two, and then the rest of the cell divides in a way that each half gets one daughter nucleus. This process is called binary fission.
Pseudopodia — Pseudopodia (meaning false feet) is the organ of locomotion in an amoeba.
Symbiosis — Symbiosis refers to a close and long-term interaction between two different types of organisms. For example, Rhizobium bacteria lives in the root nodules of leguminous plants. These bacteria provide food to the host plant and the host plant in turn provides shelter to the bacteria.
Mycelium — A network of hyphae is called mycelium.
