The microscope below is set to ×15 eyepiece and ×40 objective. A learner estimates the size of a plant cell as 0.01 mm under this magnification. If the same cell is observed under ×1000 magnification, what would be the new observed size?

A learner observed plant cells using a microscope with ×15 eyepiece and ×40 objective. She noted the cell wall and nucleus clearly but could not see the chloroplasts distinctly. She decides to increase the total magnification. Which one of the following adjustments would help her achieve this goal most effectively?  (1 mark)

Look at the animal cell as seen under a light microscope. Which part is most likely visible?

During a science lesson at Kisumu Day School, Grade 8 students are tasked with observing an animal cell under a light microscope. Each student sketches what they see. Later, the teacher asks: "Based on the limitations of a standard school light microscope, which part of the animal cell are you most likely to have seen clearly?   (1 mark)
