Yes, we can because in unicellular animals there is only one cell, when it will divide to form a new cell and hence new organisms.
All the life processes in a unicellular organism, including digestion, excretion, respiration, occur within a single cell. These cannot be seen by naked eyes and are hence called microorganisms. There are several kinds of unicellular organisms such as bacteria, protozoa, algae, fungi, etc.
Unicellular organisms reproduce by the following ways:
- The unicellular organisms reproduce by binary fission. In this, a single cell divides, giving rise to two daughter cells. This can be seen in bacteria and amoeba.
- The yeast cells reproduce by the process called budding.
- Sometimes amoeba reproduces by the process called encysting. During unfavourable conditions, it forms a protective covering around itself called a cyst. This cyst contains chitin that helps it to reproduce.
