Biology: Samples -

Set 1, Slide 87, Lateral Section, Lightfield

Stem LS

Cucurbita
Tracheid
Terminal Bud Stem Tip
Zea

The cucurbita stem sample is consisted of several layers. The sample looks as if there are two parts, but the entire sample is one lateral section of the stem. The empty space, or pith cavity, is so wide that it looks like so. The sample is comprised of many cells and other parts of the stem. The cells' structure looks like a net. The sample is green, and the cells appear to be transparent.

Interesting Layer

Image	Data	Description
	100x	This area looks like connecting two different layers. This area seems to be damaged. The pattern of this area seems similar to a torn-off wet paper.
	400x	When closed up, individual fibers that made up this layer are visible. They look like tendons of animal's muscle.

Tubular Cells

Image	Data	Description
	100x	There is a layer in which long and tubular cells are found. These cells are transparent, and their wide doesn't seem to be constant.
	400x	There are several dark substances that are found inside of the tubular cells. These look similar to nodes that are usually found on plant's stems.

Spores

Image	Data	Description
	200x	Cells on the right side of the sample contain many spores. These spores appear as if small tiny dots are packed inside of the cells.
	400x	The spores are spread throughout the cells. A few cells are stuck together, but most cells are scattered.

Interesting Tubes

Image	Data	Description
	200x	The pattern of this area looks like a ladder. This area seems to be one of pipes that pump up water or nutrients. The left pipe seems to have spiral pattern.
	400x	Interestingly, it doesn't seem to locate the entire body of the stem. Like other pipes in the sample it is slightly reddish.
