Root

 

Zea root tip sample look like a banana. It is similarly comprised of many cells like a mitosis onion root tip sample. The most cells are tightly packed together at the tip of the root. I believe the cells at the tip are playing important roles at the tip like getting nutrients from soil. An epidermis surround the cells.

Epidermis

Image Data Description

400x
The epidermis is a skin that surrounds the sample. It is much thicker than cell wall. 

400x
This part of the epidermis seems to be damaged or torn-off.

400x
The epidermis disappear at the very end of the tip. There are only cell walls that surround the sample.

Cells

Image Data Description

400x
The cells in the zea's root tip is packed tightly. The cells show distinct nuclei with nucleoli inside of them. Interestingly, the size of the cells is not stable.

400x
These cells are found inside of the very end of the root tip. These cells appear to be  bigger than other cells shown in the picture above. These cells show more details also.

Comparison

Image Data Description

400x
These cells are found in the root parts of the sample. These cells seem to transparent as if cytoplasm is missing in each cell. The cells are much bigger than other cells in tip part.

400x
In contrast by the cells in the root part, cells in tip part are much smaller and packed tightly. However, the cells in the tip part seem to show more details of internal structures.

Layers

Image Data Description

100x
The tip of the sample seems to have two different parts. These parts are seen distinctly by borders. These two parts seem to join together at the middle point.
