Question

Describe the structure of a typical protist.

Answer 1

Hint:A wide range of feeding patterns, reproductive cycles and locomotion modes are seen in protists. They have pellicle which protects them.

Complete answer:
First we should know about priests to answer this question. Protists are a category of eukaryotic species that are closely related, often unicellular, and are not animals, plants, or fungi. There is no particular characteristic that is common to all these species, such as developmental history or anatomy, and they are informally classified under a separate kingdom called Protista. Therefore, protists are no longer a systematic classification and differing forms of homology of organisms belonging to all five eukaryotic kingdoms are shown by different members. However, to describe eukaryotic microscopic organisms, it is still used as a word of use. Examples of protists are paramecium, Giant Kelp, and many parasitic protists like Plasmodium, Entamoeba histolytica etc.
The structure of typical protist contains-
A single nucleus or multiple nuclei may be found in protist cells; they vary in size from microscopic to thousands metres in region.
Protists may have cell membranes similar to animals, cell walls similar to plants, or a pellicle may cover them.
Some protists are heterotrophs and through phagocytosis consume food, whereas other forms of protists are photoautotrophs and by photosynthesis stored energy.
Many protists, with cilia, flagella, or pseudopodia, are motile and produce movement.

 Note:In reaction to the environment, many of the protists were identified as switching feeding modes from autotrophic to heterotrophic. Reproduction is primarily by binary fission or budding, enabling advanced adaptations to proceed. Sexual reproduction, however, will take on different forms as it occurs, whether self-fertilized or by cross-fertilization.
