Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Longitudinal binary fission takes place incase of
A
Paramecium
B
Planaria
C
Euglena
D
Amoeba
Explanation: 

Detailed explanation-1: -In Euglena, binary fission is longitudinal, here division occurs along the longitudinal axis. Binary fission is a process of mitosis, where cell organelles are duplicated and two separate sets of daughter cells are formed.

Detailed explanation-2: -Euglena reproduce asexually through binary fission, a form of cell division. Reproduction begins with the mitosis of the cell nucleus, followed by the division of the cell itself. Euglena divide longitudinally, beginning at the front end of the cell, with the duplication of flagellar processes, gullet and stigma.

Detailed explanation-3: -Longitudinal binary fission is seen only in Euglena. Planaria, Amoeba and Paramecium undergo transverse binary fission.

Detailed explanation-4: -> Longitudinal Binary fission-In this, cytokinesis takes place along the longitudinal axis. e.g. in flagellates like Euglena. > Oblique Binary fission-In this, binary fission cytokinesis occurs obliquely.

Detailed explanation-5: -Euglena reproduces by longitudinal binary fission.
