Which of the following statements is INCORRECT?
Binary fission occurs in a definite orientation in Leishmania.
Plasmodium divides into many daughter cells simultaneously by binary fission.
In Amoeba, the splitting of the two cells during division can take place in any plane.
Yeast can put out small buds that separate and grow further.
Plasmodium divides into many daughter cells simultaneously by binary fission.
Remember the distinction between binary fission (splitting into two, like Amoeba/Leishmania) and multiple fission (splitting into many, like Plasmodium).
Remember the distinction between binary fission (splitting into two, like Amoeba/Leishmania) and multiple fission (splitting into many, like Plasmodium).
Analyze Statement 1
Leishmania divides by binary fission in a definite orientation due to its whip-like structure (flagellum), which is a correct statement.
Analyze Statement 2
Plasmodium reproduces through multiple fission, where the parent cell divides into many daughter cells simultaneously, not binary fission. This statement is incorrect.
Analyze Statement 3 and 4
In Amoeba, the splitting can occur in any plane (irregular binary fission). Yeast reproduces by budding where small buds separate and grow. Both these statements are correct.
A: Leishmania does divide in a definite orientation, so it is a correct statement. C: Amoeba does divide in any plane, so it is a correct statement. D: Yeast does reproduce by budding, so it is a correct statement.
B is correct because Plasmodium undergoes multiple fission to produce many daughter cells simultaneously, making the claim that it uses binary fission scientifically incorrect.
When asked for the 'INCORRECT' statement, immediately scan for keywords like 'many' vs 'two' or 'specific' vs 'any' in biological process descriptions, as these are the most common points of contention.
