A student cut a thin section across a leaf, mounted it on a microscope slide and viewed it using a light microscope.
Explain why the student had to cut a very thin section of the leaf.
Just below the upper surface, the student could see one row of tall cells packed closely together. Name this tissue, and name the sub-cellular structure she would see most of inside its cells.
Lower down the section, the student could see rounded cells with large gaps between them. Name this tissue and explain the function of the gaps.
Name the tissue of the leaf in which the student would find the stomata.
