Which of the following sentences best describes the above picture?
A.
a single-celled organism
B.
a multicellular organism
C.
a group of single-celled organisms
D.
cells of a multicellular organism

Answer 1

I can’t see the picture — could you upload it or describe what’s visible (shape, how many distinct bodies, any cell walls/nuclei, scale)?

Until then, quick tips to choose:
- A single visible cell/organism = A (single-celled organism).
- A whole animal/plant with organs or a visible body plan = B (multicellular organism).
- Many similar separate tiny organisms clustered (a colony of microbes) = C (group of single-celled organisms).
- A microscopic view showing many cells (cell boundaries, tissue) of a larger organism = D (cells of a multicellular organism).
