Microscope+Work

This is the photos of our time spent working with microscopes.

Materials per group:
 * Microscope
 * Computer-based microscope
 * Digital camera
 * Glass slides and cover slips
 * Toothpicks (for cheek cells)
 * Set of stains
 * Set of acids
 * Set of bases
 * Prepared slides
 * Salt

My group did not use every single one of these materials. Something we used that was not on the list was a thin section sliced off one sprout of kale that was uprooted during repotting.

This unclear image is of unstained onion skin.

This is a closeup of what we saw close up of the onion skin.

A clearer image of the onion skin. The blocks of white and purple are the cells of the onion. Since an onion is a plant, the cells have cell walls, leading the he brick like formation.

A closer image of the cell formation. Upon closer investigation, the cells look more organic and less geometric.

Image of a leaf. The center is the dividing line of the leaf. At this magnification you cannot see the cells, although the little dots that make up the leaf may be the cells.

A unclear picture of a thin section of a sprout stem. The lines make up the cells, which gives the stem a strained look. It appears the stem's cells are longer than the leafs cells. This has been dyed with silver nitrate.

A picture of a prepared slide showing mitosis. The purple dots is the nucleus, while the blue represent the cell wall.

A image of what we saw under Dong's microscope. Clearly, he has had more success than us as this is on the lowest magnification possible. The onion cells are dyed with enriochrome black T.

A closer view of Dong's slide.

An extreme close up of Dong's slide. From this we can even see the nucleus of the cell, although which mass is it we cannot tell.
