State the term for a collection of cells, such as those in part A or part B of the leaf cross-section.
The diagram shows a magnified view of one cell from part A of the leaf cross-section. Finish the cell diagram by drawing and labelling one chloroplast and three other named cell components that would be visible, showing where they are located.
On the diagram of the leaf cross-section, use a label line to name and label one cell in the lower epidermis that would also contain chloroplasts.
Name the substance on which this enzyme acts.
Some plant cells from part B of the leaf cross-section were treated with this enzyme and then left in distilled water on a microscope slide for one hour. At the start of the hour, the cells could be seen clearly with a light microscope. By the end of the hour, the same light microscope no longer showed them clearly. Explain the structural changes in the cells that occurred between the two observations.
