Bacteria, such as E coli are simple, single-celled (unicellular) organisms. Elodea, also known as water weed, is a plant that is commonly used in aquariums. Which of the following is a main difference in cell structure between an E coli and an Elodea cell?
A.An Elodea cell does not have organized DNA, whereas E coli have organized DNA.
B.E coli have nuclei that are half the size of Elodea nuclei.
C.E coli and Elodea cells have the same cell structure because they are both simple cells.
D.E coli do not have organized DNA, whereas an Elodea cell has organized DNA.
To find the main difference in cell structure between an E coli and an Elodea cell, we need to understand the basic characteristics of cells.
E coli is a bacterium, while Elodea is a plant. Both are unicellular organisms, but they have some differences in their cell structure.
One crucial difference is in the organization of DNA. DNA is the genetic material of a cell. In the case of E coli, the DNA is not organized within a membrane-bound structure called a nucleus. E coli is a prokaryotic cell, which means the DNA is free-floating in the cytoplasm. On the other hand, Elodea is a eukaryotic cell, which has a well-defined nucleus where the DNA is organized.
Based on this information, the correct answer would be:
D. E coli do not have organized DNA, whereas an Elodea cell has organized DNA.
