The cell theory applies to all organisms, including the 5 shown in the picture. which of the following statements describes how these organisms are an example of the cell theory?

a) the organisms have cells that lack a nucleus.

b) the organisms are made of one or more cells.

c) the cells of the organisms undergo photosynthesis.

d) the cells of the organisms are identical to each other.

Correct B

All of these organisms are made up of at least one cell. The fourth one (Euglena) is a unicellular organism (made up of 1 cell), and the rest are multicellular organisms (made up of many cells).

Incorrect Answers:

A.

All of these organisms are not only made up of cells, but more specifically these organisms are all made up of eukaryotic cells. This means that their cells have a nucleus. The other classification of cells (prokaryotic cells) do not have a nucleus. These are basically just bacteria, and there are no bacteria pictured in this problem, so this is a false answer choice.

C.

Some of these organisms undergo photosynthesis, but not all of them do. Photosynthesis is the process in which organisms convert sunlight, water and CO2 into glucose and oxygen. This is how plants (and some other special organisms as well) "make their own food". There are several organisms on this list that are not green plants, so this is a false statement.

D.

Although these organisms are all made up of eukaryotic cells (having a nucleus), their cells are definitely not identical. One major difference is that between a PLANT eukaryotic cell and an ANIMAL eukaryotic cell (***see pic below***). Other differences would be seen as well if we compared cells from all of these organisms under a microscope, so this is a false answer choice.

it has one origin of replication, but it proceeds in two directions - d)
