1) The mitochondrion length in nanometers is 85,000 nm.
2) Magnification = Image size/Actual size = 1.3 cm/85,000 nm = 15,294.12
3) The image size of the nucleus is 4.3 mm.
4) i) The actual length of the nucleus is 2.8 micrometers = 2,800 nm.
ii) The student's estimate was accurate.
Image size of mitochondrion: 1.3cm
1 mm division = 65 nm
1) What is the mitochondrion length in nanometers?
2) Calculate the magnification. Show your working out.
3) A student predicts that the nucleus length of this cell is 2.8 micrometers.
Use this value and the magnification calculated in question 2 to find out the Image size of the nucleus. Give your answer in mm.
4) Was this student accurate in determining the actual length of the nucleus?
i) Use the triangular equation and the answers to questions 2) and 3) to calculate the actual length.
ii) Confirm the accuracy of the student's estimate
