Biological classification is an important topic for NEET aspirants and should be well understood to develop understanding and relation between different organisms and their characteristics. Let us take a glance at one of the important topics “Kingdom Protista” in this NCERT based notes.
Euglena
Slime Mould
Slime moulds are a type of protist that feeds on decaying organic material. They move along decaying twigs and leaves, engulfing organic matter.
There are four major groups of protozoans:
(i) Amoeboid Protozoans:
(ii) Flagellated Protozoans:
(iii) Ciliated Protozoans:
Paramoecium
(iv) Sporozoans:
Now you can try answering the questions from Kingdom Protista asked in NEET:
Q.1. Pseudopodia help amoeboids in _______
(a) locomotion
(b) ingestion of food
(c) locomotion and ingestion of food
(d) performing metabolic reactions
Correct Answer is Option (c)
Pseudopodia help amoeboids in both locomotion and ingestion of food. Pseudopodia are temporary extensions in amoeba that help them to move to as well as intake food by surrounding it with temporary extensions.
Q.2. Amebiasis is caused due to _______
(a) Amoeba proteus
(b) Entamoeba histolytica
(c) Chaos carolinense
(d) Trypanosoma
Correct Answer is Option (b)
Entamoeba histolytica is a parasitic amoeba in humans which in turn causes Amoebiasis. Amoebiasis results in abdominal pain, diarrhoea, blood in stool, fever and loss of appetite.
Attempt this test to check your knowledge about Kingdom Protista:
Test: Kingdom Protista
Additional information on Amoeba and Entamoeba histolytica.
(a) Amoeba proteus: The Proteus Animalcule.
2. Digestion: The food is digested in the food vacuole with the help of enzymes.
3. Absorption: It is then absorbed in the cytoplasm of the Amoeba by diffusion.
4. Assimilation: The absorbed food provides energy and a part of nutrition is used for growth.
5. Egestion: The undigested and the waste food particles are thrown out.
(b) Entamoeba histolytica
