Question

Is Euglena a plant like or animal like protist?

Answer 1

Any eukaryotic creature that isn't an animal, plant, or fungus is referred to as a protist. While protists are believed to have a common ancestor, As a result, certain protists may be more closely related to animals, plants, or fungus than to other protists; nonetheless, the category is used for convenience, as it is for algae, invertebrates, or protozoans. Protistology is the scientific study of protists.

Complete answer:
Euglena is a plant-animal, which means it is neither plants nor animals despite the fact that they have characteristics of both.
Scientists have struggled to identify the cell Euglena since it is neither a plant nor an animal. Scientists were so perplexed that they established a new kingdom called Protist just to cope with them. The misunderstanding around Euglena stems from the fact that it acts like a plant in the day yet acts like an animal in the dark.
Euglena possesses chloroplasts, which enable it to photosynthesize, as well as a rudimentary eye-spot, which detects light and causes the cell to alter its location in order to maximize photosynthesis. Euglena does not have a cell wall, which is a distinguishing characteristic of plant cells, and instead protects itself with a pellicle formed of protein bands.
When Euglena is in the dark, though, she takes on an animal-like appearance. Instead of receiving energy from photosynthesis, Euglena cells will grasp their food in the dark, spit acid on it, and suck it up, a process similar to holozoic feeding. Furthermore, Euglena cells feature flagellum, which are characteristics of animal cells and allow the cells to move.

Therefore,Euglena is a plant animal with a mixotrophic mode of nutrition.

Note:
Mixotrophic nutrition refers to creatures that are both autotrophic and heterotrophic. Instead of having a single trophic mode on the continuum from full autotrophy at one end to heterotrophy at the other, a mixotrophic organism can utilise a variety of distinct sources of energy and carbon. Euglenoids in the protist kingdom are mixotrophs in nature.
