To calculate the real size of the cell, we need to divide the size of the image by the magnification.

Step 1: Convert the size of the image from mm to µm. 1 mm = 1000 µm. So, 25 mm = 25,000 µm.

Step 2: Divide the size of the image (in µm) by the magnification to get the real size of the cell in µm. So, 25,000 µm ÷ 100,000 = 0.25 µm.

Step 3: Convert the real size of the cell from µm to nm. 1 µm = 1000 nm. So, 0.25 µm = 250 nm.

So, the real size of the cell is 250 nm.

Question

To calculate the real size of the cell, we need to divide the size of the image by the magnification.

Step 1: Convert the size of the image from mm to µm. 1 mm = 1000 µm. So, 25 mm = 25,000 µm.

Step 2: Divide the size of the image (in µm) by the magnification to get the real size of the cell in µm. So, 25,000 µm ÷ 100,000 = 0.25 µm.

Step 3: Convert the real size of the cell from µm to nm. 1 µm = 1000 nm. So, 0.25 µm = 250 nm.

So, the real size of the cell is 250 nm.
