Question

how are protozoans differentiated by means of their locomotory organelles

Answer 1

Hey friend !!!


On the basis of organs of locomotion , the protozoa are divided into four classes. They are named as
1) Sarcodina 2) Mastigophora 3) Cilliata 4) Sporozoa
1) Sarcodina:- These are protozoa with organs of locomotion as pseudopodia which means false foot Example Amoeba
2) Mastigophora;- These are protozoa with organs of locomotion as flagella. The number of flagella are different in different protozoa.
3) Cilliata:- These are protozoa which have organs of locomotion as cilia . Cillia are small hairs like structure seen. These are many in numbers on the body of animals. Example Paramecium
4) Sporozoa:- These are protozoa which have no organs of locomotion


Hope this helps you :)

Answer 2

Answer:

Protozoa can be categorized into three forms according to their locomotory movement:

1. Amoebic
2. Flagellate
3. Ciliate

Explanation

Amoebic protozoa

These types of protozoa move in an amoebic form. This type of movement is achieved when the protozoa develop a flagellum in the direction of its movement while on the opposite side diminish the previously formed flagellum.

Flagellates

These are protozoa that have flagella as a locomotory organ.

The flagella is a highly vibratile, centriole based, thread-like locomotory organs.

Ciliates

Ciliates are protozoa that have cilia as thier locomotory mechanism.

The cilia are similar in structure to the flagella, but are shorter, hair-like and and numerous around the protozoa.

The cilia provide faster and a more co-ordinated movement in the protozoa.
