How do Organisms Reproduce?

Activity . Observe a permanent slide of Amoeba under a microscope. Similarly observe another permanent slide of Amoeba showing binary fission. Now, compare the observations of both the slides.

However, some unicellular organisms show somewhat more organisation of their bodies, such as is seen in Leishmania (which cause kala-azar ), which have a whip-like structure at one end of the cell. In such organisms, binary fission occurs in a definite orientation in relation to Figure . (b) Figure . (b) Figure .

Yeast, on the other hand, can put out small buds that separate and grow further, as we saw in Activity . .
