Class Trypanistomatida contains two infectious genera: Leishmania and Trypanosoma, and these two genera account for three of the most debilitating, widespread, and prevalent diseases of humans: leishmaniasis, Chagas disease, and sleeping sickness.

Flagellar Movement A euglena moves by whipping, twisting, turning its flagellum around like that of a propeller. The locomotory flagellum is equal to the length of the Euglenoid’s body and it highly helps it to swim freely in water. In Euglena, the Flagellum lies in the anterior end towards the side bearing the stigma.

Flagella (singular = flagellum) are long, hair-like structures that extend from the plasma membrane and are used to move an entire cell, (for example, sperm, Euglena). They serve the same function in both prokaryotes and eukaryotes (to move an entire cell).

Active flagella provide the propulsion mechanism for a large variety of swimming eukaryotic microorganisms, from protists to sperm cells. The fast spinning motion of the locomotory flagellum of the alga Euglena gracilis constitutes a remarkable exception to these patterns.

Euglena is entirely unicellular, has no collagen and no cellulose, stores energy in paramylon bodies (not starch as plants do).

Euglena are single celled organisms that belong to the genus protist. As such, they are not plants, animal or fungi. In particular, they share some characteristics of both plants and animals.

In absence of proper sunlight, euglenas go around in water hunting for food. One of the most interesting facts about euglena is its eyespot, which is actually a pigmented organelle found in the anterior and is highly sensitive towards light. This eyespot helps it to detect sunlight for photosynthesis.

These organisms are parasites that can cause serious blood and tissue diseases in humans, such as African sleeping sickness and leishmaniasis (disfiguring skin infection). Both of these diseases are transmitted to humans by biting flies.

Chloroplasts within the euglena trap sunlight that is used for photosynthesis and can be seen as several rod-like structures throughout the cell. In the center of the cell is the nucleus, which contains the cell’s DNA and controls the cell’s activities.

Complete answer: Euglena doesn’t have a cellulosic cell wall. Kingdom Protista includes groups like chrysophytes, dinoflagellates, euglenoids, slime moulds, and protozoans. Members of the Kingdom Protista are primarily aquatic. The majority of the euglenoids are freshwater organisms found in stagnant water.

Euglena has chloroplasts that allows it to photosynthesize, and a primitive eye-spot which detects light in order for the cell to shift it’s position to maximize its photosynthesis. Euglena does lack a cell wall, a defining feature of plant cells, instead having a pellicle made of protein bands to protect itself.

As the food is taken in, a food vacuole is formed in which digestive enzymes break down its prey. After digestion, the waste is expelled through the process of exocytosis. Also visible in the amoeba is the nucleus, which contains the amoeba’s DNA.

Euglena move by a flagellum (plural ‚ flagella), which is a long whip-like structure that acts like a little motor. The flagellum is located on the anterior (front) end, and twirls in such a way as to pull the cell through the water.

The Euglena surrounds the particle of food and consumes it by phagocytosis, or in other words, engulfing the food through its Pellicle layers and then takes it inside through the cell membrane. It is being researched that Euglena secretes various digestive enzymes that are typically animal-like in nature.

This suggests that the photoresponse to red, green, and blue light is likely to be important in the development of Euglena chloroplasts.

Euglenas create their own food through photosynthesis, the process of absorbing sunlight to synthesize foods from carbon dioxide and water. An eyespot at the front end of the euglena detects light, and its chloroplasts (structures that contain chlorophyll) trap the sunlight, allowing photosynthesis to occur.
