Stem CS

 

A sample of a zea stem is mostly made up of cells. A group of these cells are called ground parenchyma. There are many distinct areas that appear as tiny dots. These areas are called vascular bundle. The outer edge of the stem is called epidermis.

Vascular Bundle

Image Data Description

400x
A vascular bundle is basically comprised of xylems, phloem, and bundle sheath. The vascular bundle seems to play an important role in transporting nutrients throughout the stem. 

400x
Xylem are two big circles in the vascular bundle. The xylems look similar to water pipes. The xylems are not as big as other cells, but they seem to bigger than phloem.

400x
A phloem is a net shaped area in the vascular bundle. The phloem looks like a filter.

Epidermis

Image Data Description

200x
An epidermis is the outer edge of the stem sample. It is comprised of many tiny cells. These cells are much smaller than other cells.

1000x
It looks like two cells are combined together, so it seems like a cell with two nucleus in it. The color of this cell is different from others. 

Ground Parenchyma

Image Data Description

400x
Ground parenchyma is a group of many cells. The cells found in the parenchyma are big and wide. However, the sizes of these cells are not constant. Also, some cells are filled with greenish substance inside.

1000x
When focused closely, the cells seem to contain very tiny objects. These objects are somewhat similar to spores. These are found mostly near the cell walls.
