Like bacteria , plant cells have cell walls , and contain organelles such as chloroplasts in addition to the organelles in other eukaryotes.
Do Protists Have Cell Walls. Cell walls are not unique to fungi and plants; Protist cells may contain a single nucleus or many nuclei;

Others, such as chlorella, have chloroplasts and are more like plants. Is this organism heterotrophic, autotrophic or if this is possible, does it have cell walls? Protists do have a cell wall and there cell walls are composed of cellulose, protein strips(pellicle) and silica.
Plant cell walls are composed mainly of cellulose, whereas fungal cell walls are rich in chitin.
This extracellular matrix is characteristically absent from animal cells, although animal cells have extracellular matrix components on their surface. Protist cells may contain a single nucleus or many nuclei; From the outermost layer of the cell wall, these layers are identified as the middle lamella. Protists exhibit great diversity in size, shape and structure.
