Surface of Leaf

This is clearly multiple layers thick. Layers are visible beneath the top, focused layer. The leaf seems to have a slighly darker row of cells near its edge. Nuclei are much less visible than with the onion root.

Image	Data	Description
	200x	The darker edges of the upper layer of cells appear clear and distinct in comparison to those of the layers below. There is a "texture" to the stuff of the cells that looks like to magnification protists. I hesitate to call this stuff the cytoplasm of the cell as the texture seems too great.
	200x	Many interesting dead organisms such as diatoms, are found on the leaf's surface.
	400x	Here, two long thin UFO-shaped diatoms can be seen.
	1000x	At 1000x with oil, large organelles are visible. The top layer of cells' organelle has a definitive bubbly texture to it. I'd like to assume that this is the nucleus, but no distinct chromosomes can be seen as with the onion root tips. Their empty nature makes me wonder if they are some sort of vacuole.

Midrib

Midrib is a term for the dark line found at the middle of the leaf.

Image	Data	Description
	100x	The midrib seems to have several horizontal lines on it. This may just be the accumulation of overlapping cell walls of higher-layers of cells.
	400x	At 400x though, the lines seem more pronounced and even a little bit "rougher".

Thorns

There are several thorns found at the tips of the leaf's serrations.

Image	Data	Description
	200x	The internal structure of the thorn is visible. It rather resembles the "quick" of a cat's claw.
	1000x	At 1000x, an orange edge of the thorn is visible. This could very well be tougher material than a standard cell and more suitable for puncturing purposes.

Shaded Part

Image	Data	Description
	200x	Those dark bits seen in the sample image are more obviously individual cells at 200x. Probably, they just soaked up more of the stain, but they look like they don't have the electric lights of their neighbors.
