The individual cells making up a tissue differ from single-celled organisms such as paramecium in that only the latter:
a. reproduce by mitosis.
b. have subcellular organelles.
c. are capable of extended independent life.
d. can metabolize nutrient molecules.

C. are capable of extended independent life.

Explanation:

The single-celled organisms such as Paramecium have only one cell in their bodies. The cells of the unicellular organisms are capable of independent existence as an individual organism. On the other hand, the cells that make up a tissue are not able to survive as an individual organism. The cells of the tissue are specialized to perform some specific functions and cannot perform all the life process independently as the single cell of Paramecium does.
