Reproduction
Euglena shows two types of reproduction, i.e, binary and multiple fission. No Sexual reproduction.
Binary Fission
- Euglena secretes a protective wall around it and makes itself encysted under unfavorable conditions.
- After the encysted stage, two solitary daughters are formed when the organism splits longitudinally.
- The splitting starts from the former end and moves backward. The nucleus elongates and divides into two.
- Finally, the individual is split into two, each half receiving one daughter nucleus.
Multiple Fission
- In the encysted stage, the nucleus splits often and a huge number of minute daughter nuclei are generated.
- The cytoplasm smashes up and a small amount surrounds each daughter nucleus and various minute animals called flagellate are generated.
- Under favorable conditions, the flagellate comes out of the cyst and passes a short period through the amoeboid stage, develop into adult Euglena.

Biological classification is a scientific plan that consists of arranging organisms into taxonomic groups and subgroups based on their similarities and dissimilarities. The word Biology was first coined by Lamarck and Treviranus in 1802. It is mandatory to classify organisms for numerous reasons. Aristotle was the first scientist to take a step toward the classification of organisms.
Cells are one of the most crucial features of living organisms, as they are the building blocks of life. They perform particular functions. All of these cells join to form a tissue. There are plenty of living organisms present in this world. Mega biodiversity regions are those which are humid and warm because they provide the optimum temperature and nutrients for the development of species. Two kingdom system was proposed by Linnaeus, which includes Plantae and Animalia kingdoms. The five-kingdom system was proposed by R.H Whittaker in 1969 which included Monera, Protista, Fungi, Plantae, and Animalia kingdoms.
