how does the size of the photosynthetic prokaryotic cell (anabaena) compare with that of the photosynthetic eukaryotic cell (elodea)?
a. the photosynthetic prokaryotic cell is 18 times smaller than the photosynthetic eukaryotic cell.
b. the photosynthetic prokaryotic cell is 18 times bigger than the photosynthetic eukaryotic cell.
c. the photosynthetic prokaryotic cell is about the same size as the photosynthetic eukaryotic cell.
d. the photosynthetic prokaryotic cell is 45 times smaller than the photosynthetic eukaryotic cell.

Explanation:

Prokaryotic cells like Anabaena are generally much smaller than eukaryotic cells like Elodea cells. Prokaryotic cells lack membrane - bound organelles and a nucleus, which contributes to their smaller size. Eukaryotic cells have a more complex structure with various organelles and a larger volume. Typically, prokaryotic cells are around 1 - 10 micrometers in size while eukaryotic plant cells like Elodea can be 10 - 100 micrometers. A common ratio is that prokaryotic cells are about 10 - 20 times smaller, and 18 times smaller is a reasonable estimate.

Answer:

A. The photosynthetic prokaryotic cell is 18 times smaller than the photosynthetic eukaryotic cell.
