The organism represented in the above image - is a chromalveolate. - is a flagellate. - makes pseudopodia. - is an excavate. - is in the genus Euglena. - is in the genus Amoeba.

- is a flagellate. - is an excavate. - is in the genus Euglena.

At one time, biologists thought that fungi were merely forms of plants that had lost their chlorophyll and had returned to saprotrophy to gain food. Why is this no longer considered a solid theory? -Fungal cell walls contain chitin rather than cellulose. -Plants are multicellular and fungi are unicellular or multinucleated noncellular plasmodia. -Fungi attack and engulf food for internal digestion. -Plants store glycogen, while fungi store starch. -Fungi have flagella at some stage, providing mobility that plants never have.

-Fungal cell walls contain chitin rather than cellulose.

a hypha. Fungi have a filamentous body; an individual filament is called a hypha, while the collective mass of filaments is called a mycelium.
