Based on Figure 12.10, which statement accurately identifies the microscopy techniques and the relative scales of the animal and plant cell cytokinesis images?
A: Figure 12.10a (animal cell) uses Transmission Electron Microscopy (TEM) with a 1 μm scale, while Figure 12.10b (plant cell) uses Scanning Electron Microscopy (SEM) with a 100 μm scale.
B: Figure 12.10a (animal cell) uses Scanning Electron Microscopy (SEM) with a 100 μm scale, and Figure 12.10b (plant cell) uses Transmission Electron Microscopy (TEM) with a 1 μm scale.
C: Both figures use Scanning Electron Microscopy (SEM), but the animal cell is shown at a significantly higher magnification due to its smaller scale bar.
D: Both figures use Transmission Electron Microscopy (TEM), with the plant cell shown at a much lower magnification to capture the entire cell wall structure.
Explanation
Figure 12.10a, showing the animal cell cytokinesis, is labeled as an SEM Scanning Electron Micrograph and has a scale bar of 100 μm. Figure 12.10b, showing the plant cell cytokinesis, is labeled as a TEM Transmission Electron Micrograph and has a scale bar of 1 μm. This means the animal cell image provides a surface view at a larger scale, while the plant cell image provides an internal view at a much finer, higher magnification scale.
