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.

not sure but try c two haploid cells

explanation:

photosynthesis makes the glucose that is used in cellular respiration to make atp. the glucose is then turned back into carbon dioxide, which is used in photosynthesis. while water is broken down to form oxygen during photosynthesis, in cellular respiration oxygen is combined with hydrogen to form water.
