Key Points
- Leishmania is a genus of protozoan parasites that has a whip-like structure called a flagellum at one end of the cell.
- These flagella are crucial for the motility of the organism, aiding in its movement and infection processes.
- Binary fission in Leishmania occurs in a specific orientation, ensuring that the division is coordinated with the position of the flagellum.
- The presence of flagella and orientation-specific binary fission are key characteristics that distinguish Leishmania from other unicellular organisms.
Additional Information
- Flagellum
- A flagellum is a long, whip-like structure that protrudes from the cell body and is used for locomotion and sensory functions.
- In many protozoa, flagella are vital for movement, allowing them to swim through liquid environments.
- Binary Fission
- Binary fission is an asexual mode of reproduction common among unicellular organisms.
- During binary fission, the parent cell divides into two equal-sized daughter cells.
- Leishmaniasis
- Leishmaniasis is a disease caused by infection with Leishmania parasites, which are spread by the bite of infected sandflies.
- It can cause skin sores, fever, and damage to the spleen and liver.
- Protozoa
- Protozoa are a diverse group of unicellular eukaryotic organisms.
- They can be free-living or parasitic and are found in various aquatic environments and soil.
