Answer
Spirogyra
Reason — Spirogyra is a multicellular green algae. Spirogyra is made up of many cells joined end-to-end, forming a long filament. Although Spirogyra looks like a thread, that thread is actually made up of many rectangular cells arranged in a row.
A unicellular organism is made up of only one cell. Bacterium is single-celled organism. Paramecium single-celled protozoan. Chlamydomonas single-celled green alga.
