Question

All organisms are made up of cells. Some organisms are unicellular, or made up of just one cell. Other organisms are multicellular, or made up of many cells.
These micrographs, or magnified pictures taken with a microscope, show cells from organisms of four different species.
An irregularly-shaped cell with several smaller structures within.

Several box-shaped cells of varying lengths and containing green structures are side-by-side.

Tripos gracilis, made up of one cell

Cells of Hydrilla verticillata

Several irregularly-shaped cells containing purple-stained structures are side-by-side.

A vaguely oval-shaped cell contains several smaller structures.

Cells of Homo sapiens

Ganeo tigrinum, made up of one cell

Which of the following statements are true about the organisms shown in the micrographs above? Select all that apply.

Answer 1

True statements:
- Tripos gracilis is unicellular (made of one cell).
- Ganeo tigrinum is unicellular (made of one cell).
- Hydrilla verticillata is multicellular (many box-shaped plant cells visible).
- Homo sapiens is multicellular (many irregular animal cells visible).
- Hydrilla cells contain chloroplasts (the green structures).

(Everything shown is made of cells.)
