Question

all of the following are a part of the current cell theory except
large organisms have fewer cells
all living things are made of cells
new cells are produced from old cells
the cell is the basic unit of living things

Explanation:

Cell theory states that the cell is the basic unit of living things (so the first option is part of cell theory), new cells are produced from old cells (so the second option is part of cell theory), and all living things are made of cells (so the third option is part of cell theory). However, large organisms have many cells, not fewer.

Answer:

large organisms have fewer cells
