Question

‌Which of the following is the correct matched pair?
A. Amoeba- pseudopodia
B. Plasmodium- cilia
C. Euglena- cilia
D. Paramoecium- flagella

Answer 1

Hint:
In all given options, the organism is given on the right hand side and on other side the type of movement or locomotion performed by that organism is given. So, we need to find the correct match among organisms and its locomotion or movement. Cilia and flagella help in the locomotion of many microorganisms.

Complete answer:
Amoeba is a single-celled organism, a Protozoa and has the unique ability to change its shape by extending its some of the outer surface. This ability to change shape is also known as pseudopodia. Amoeba digest its food particles by the same mechanism of extending the outer surface, then make a vacuole and engulf that vacuole with food particles inside the cell.
Plasmodium is a unicellular eukaryotic organism having parasitic properties for many vertebrates and insects. Some strains of it are also responsible for causing disease like malaria. You must know which strain it is. Plasmodium has its own actin or myosin protein- based motors to perform locomotion. Thus, Plasmodium does not require cilia.
Euglena is a genus of many unicellular flagellate eukaryotic microorganisms. Some species are used as model organisms as well. Most of the Euglena have photosynthetic mechanisms for food preparation. Thus, it may have a green colour. Euglena have flagella for locomotion.
Paramoecium is a single-celled ciliate organism. That means it has cilia for its locomotion. It feeds on microorganisms like bacteria, algae, yeast, etc. To get food, Paramoecium makes movements with cilia to sweep prey organisms.
So, to find the correct match we will go one by one.
Option A – is a correct match. Because Amoeba shows pseudopodia.
Option B – is not correct because Plasmodium have flagella for locomotion not cilia thus this option is not correct.
Option C – Euglena have flagella for locomotion not cilia thus this option is not correct.
Option D – Paramoecium is an organism which has cilia for its locomotion or movement. Thus, option D is also not correct which gives it a flagella, which is incorrect.

Hence, option A is correct.

Note:
We generally forget which organism have cilia and which organism have flagella for movement or locomotion. So, learn and understand which organisms have which type of outer surface structure and how it helps in movement or locomotion.
