A student uses a microscope to observe plant palisade mesophyll cells.
Palisade cells contain chloroplasts. What is the main function of chloroplasts?
Name one type of plant cell that does not contain chloroplasts.
Under a microscope, the image length of a single chloroplast is measured to be 5.6 cm. The real length of this chloroplast is 3.5 μm3.5\ \mu\text{m}3.5 μm. Calculate the magnification of the image.
Use the equation:
magnification=size of imagereal size of object \text{magnification} = \frac{\text{size of image}}{\text{real size of object}} magnification=real size of objectsize of imageShow your working.
State two advantages of using an electron microscope instead of a light microscope to study the internal structure of organelles like chloroplasts.
