of prokaryotic and
eukaryotic cells youve
learned about, what kind of
cell is this?

1. cell type a is
2. cell type b is

these cells of bacillus megaterium are about 2.5 - 4μm (original
magnification lm 320x). there is no visible nucleus present in any
of these cells.

Explanation:

Prokaryotic cells, like bacteria (here Bacillus megaterium), are generally small (the cells in the image are about \(2.5 - 4\mu m\), which is in the size range of prokaryotes). A key characteristic of prokaryotes is the absence of a membrane - bound nucleus. The text below the image of Cell Type A explicitly states “There is no visible nucleus present in any of these cells”. Eukaryotic cells, on the other hand, have a true nucleus (a membrane - bound organelle that houses the cell’s genetic material).

Answer:

Prokaryotic cell
