During a salt-marsh survey, researchers record a multicellular plant and several organisms that each consist of a single cell. Which statement correctly compares their organisation?
Each single-celled organism is a tissue made from one cell; the plant is an organism made from tissues.
Each single-celled organism is a cell but not an organism; the plant is an organism made from cells.
In each single-celled organism, the one cell is also an organ; in the plant, each organ is made of only one tissue.
In each single-celled organism, one cell is also the whole organism; in the plant, similar cells form tissues within the organism.
