What does celled mean?
Celled is an adjective meaning having cells or chambers of a particular kind, and in modern English it survives almost entirely as the second half of compound adjectives such as 'single-celled', 'many-celled', and 'four-celled'. Biologists use it constantly to classify organisms: bacteria are single-celled, lacking a nucleus, while animals, plants, and fungi are many-celled, their bodies built from countless specialized units. The word also extends beyond biology to any structure divided into compartments, such as a multi-celled beehive or battery. Its connotations are strictly scientific and neutral rather than emotional. Though it looks like a standalone word, 'celled' rarely appears independently — you would not normally call something simply 'celled' without specifying how many cells or what kind. It derives ultimately from the Latin cella, meaning a small room or storeroom, the same root that gives us 'cell' and 'cellular'. For students of biology, it is an indispensable building block of precise description, turning a bare noun into a compact classifier.
adjectiveHaving cells or compartments of a specified kind; used chiefly in combination, as in 'single-celled' or 'many-celled'.
- (in combination) having cells of a specified number or kind, as in single-celled or four-celled
"Bacteria are simple single-celled organisms that lack a true nucleus."
"Amoebae are single-celled creatures invisible to the naked eye."
"The honeycomb's six-celled structure is a marvel of natural engineering."
Every living thing you can see without a microscope is many-celled — but the word itself is just Latin for 'little room', stuck on the end of other words.

Etymology of celled
Celled is formed from the noun 'cell', which English borrowed from Old French cele, from Latin cella meaning a small room, storeroom, or chamber. The adjective arose by straightforward derivation — adding -ed to indicate possession, in the same pattern as 'gifted' or 'talented'. It gained its scientific prominence in the seventeenth century when Robert Hooke applied 'cell' to the tiny box-like structures he observed in cork under his microscope. Cognate forms include 'cellular' and 'cellar', all tracing back to the same Latin root.
