A student prepared a temporary wet mount slide of Elodea (water weed) leaf cells to view under a light microscope.
a.[2]
Name two pieces of laboratory equipment or consumables, other than the microscope itself, that the student would use to prepare this slide.
b.[2]
Below is a diagram of a light microscope:
Name Part P and describe its function.
c.[4]
Compare the structure of a plant cell (such as an Elodea cell) with the structure of an animal cell (such as a human cheek cell).
d.[2]
When an Elodea cell is placed in a highly concentrated sucrose solution, its protoplast shrinks and pulls away from the cell wall. Explain why the protoplast shrinks, and how the presence of the cell wall prevents the cell from completely losing its overall structural shape.
