Scelta multipla
You isolate a cell with the following characteristics: (1) no nucleus, (2) a cell wall, and the cell is (3) 2 μm in size. This cell could be a/an:
A
Bacterium.
B
Plant cell.
C
Animal cell.
D
Bacterial cell or a plant cell.
E
Plant cell or an animal cell.
Guida verificata passo dopo passo1
Identify the characteristics of the cell: no nucleus, a cell wall, and a size of 2 μm.
Recall that eukaryotic cells, such as plant and animal cells, have a nucleus, whereas prokaryotic cells, like bacteria, do not.
Consider the presence of a cell wall. Both plant cells and bacterial cells have cell walls, but animal cells do not.
Evaluate the size of the cell. Bacterial cells are typically around 1-10 μm, while plant and animal cells are generally larger.
Based on the absence of a nucleus, presence of a cell wall, and small size, conclude that the cell is most likely a bacterium.
