Euglena vs. Paramecium

The main difference between Euglena and Paramecium is that Euglena can either be a plant-like or animal-like organism, whereas Paramecium is only an animal-like organism.

Key Differences

Euglena expresses the qualities and characteristics of both plants and animals; on the other hand, paramecium only shows attributes of animals.
Euglena contains a pellicle which allows them the flexibility, while there is no pellicle present in paramecium.

Chloroplasts is present in euglena; on the flip side, the chloroplast is not present in paramecium.
The survival rate of euglena is high because it can survive prolonged droughts without light and water. In contrast, paramecium cannot survive in long droughts and without the availability of favorable conditions.
Euglena feeds on food particles or undergoes photosynthesis; on the contrary, paramecium either undergoes photosynthesis or gets food through predation.
Euglena consists of flagella and uses it for its propagation; on the contrary, paramecium consists of cilia and uses it for its propagation.

Euglena and Paramecium Definitions

Euglena

Paramecium

Any of various slipper-shaped freshwater ciliate protozoans of the genus Paramecium, having an oral groove for feeding.

Euglena

(biology) Any of several protists, of the genus Euglena, that contain chloroplasts and a single flagellum.

Paramecium

An oval-shaped protozoan organism of the genus Paramecium.

Euglena

Minute single-celled green freshwater organism having a single flagella; often classed as algae

Paramecium

Any member of the genus Paramecium

Euglena vs. Paramecium

Euglena is considered as a unicellular, green, freshwater organism having a flagellum; on the other hand, paramecium is regarded as a unicellular, freshwater animal with a distinctive shoe-like shape. The structure of euglena can be animal-like or a plant-like; on the contrary, the structure of paramecium is only an animal-like.

Euglena consists of a chloroplast, while paramecium does not consist of its chloroplast; instead, it swallows green algae. Euglena takes particles of food; on the flip side, paramecium snatches food through predation. The feeding mechanism of euglena is that it either undergo photosynthesis or ingest food particles; on the other hand, the feeding mechanism of a paramecium is that it either undergoes photosynthesis or latches food through predation.

For propagation, euglena uses a flagellum; on the flip side, paramecium uses cilia for their propagation. Euglena is mainly sensitive to light and moves towards the sun, whereas paramecium is primarily sensitive to light, temperature, chemicals, and as well as touch. Only asexual reproduction occurs in euglena; on the flip side, paramecium goes through both sexual and asexual reproduction.

Euglena is known both a heterotroph and autotroph; on the contrary, paramecium is mainly a heterotroph. Euglena can survive through prolonged droughts without the availability of water or light, but in contrast, paramecium cannot escape through prolonged droughts and in unfavorable conditions.

The pellicle is present in euglena, which enhances their flexibility, while on the other hand, no pellicle is present in paramecium. Euglena consists of a tail that aids it in the swim, while paramecium does not have a tail.

What is Euglena?

Euglena is referred to as a green, freshwater organism, unicellular having a flagellum. Euglena mainly possesses characteristics of plants and animals. It resembles a plant because it also consists of the chloroplast. If the light and favorable conditions are available, then it also undergoes photosynthesis.

The chloroplast present in euglena is scattered throughout in its cell. Euglena consists of pyrenoids, which are considered microcompartments present inside the chloroplast, function in operating carbon-concentrating mechanisms.

The food in euglena is stored in the form of starch granules. Animal-like characteristics are also present in euglena. Euglena consists of an eyespot that is present for the detection of light.

A cell wall is not present in euglena; preferably, it consists of a pellicle. The pellicle is mainly made up of a protein layer, which is typically arranged around the cells of the euglena. Microtubules are responsible for holding the pellicle. The sliding of the pellicle strips offers and enhances flexibility and contractility to euglena.

The sliding process of the pellicle is known as metaboly. The gullet present in euglena serves as a reservoir of food. For the locomotion of euglena, it consists of a flagellum. Euglena also consists of the contractile vacuole, which is known as myoneme, which also assists in the movement of euglena, as well as this contractile vacuole is also involved in osmoregulation and the excretion of waste material.

What is Paramecium?

Paramecium is referred to as freshwater, unicellular, having the characteristics of animals. It looks like the sole of the shoe in its appearance. 0.3 mm is the approximate length of the paramecium. Paramecium is considered the scientific, generic name, and as well as it is used as the common name.

Paramecium consists of cilia, and its outer surface is covered with cilia. Cilia plays a vital role in the locomotion of the paramecium. When cilia beat toward backward, the forward movement of a paramecium is achieved, and when cilia beat toward a forward direction, the paramecium moves backward.

Inside the cell of the paramecium, a small micronucleus and a large micronucleus can be identified. The oval groove is present on one side of the paramecium. The oval slot forms a gullet and ends up with a cytostome.

The cilia of paramecium are also involved in feeding through passing the food directly into the gullet. Paramecium gets food through predation and sometimes through photosynthesis as it swallows the green algae. The ingested food is typically digested in the vacuole, and then the waste materials are excreted out through the anal pore of the paramecium.

Under favorable conditions, paramecium reproduces through asexual reproduction by the process of binary fission. Paramecium reproduces through sexual reproduction by the process of conjugation under unfavorable conditions. Paramecium is primarily sensitive to the changes that occur in the environment, for example, light, temperature, chemicals, and as well as touch.
