Set 1, Slide 51, Wet Mount, Lightfield
Onion Epidermis 40xOnion's epidermis is comprised of many plant cells. These plant cells are organized in order, because their cell walls bond each other. The epidermis seems to be stained. Many nucleuses are found inside of the epidermis.

Plant Cell Structures

Plant cells stick to each other and are arranged in order. The shapes of the plant cells vary from quadrilateral to multi-gon.

Some plant cells have nucleus, and some do not. The background of the cells looks like a worn-out paper.

There is no space between the plant cells. The cells are attached each other closely.

Nucleus

The nucleus are found inside of the plant cells. The nucleus are circular and darker than the plant cell's background.

The nucleus at the middle has two dots on it. These two dots seem to be substances of the cells.

At 1000x, the nucleus shows internal structure including a black dot and several white spots.

Black Particles

On the slide, there are some areas where are comprised of black particles. These particles seem to be part of the onion's epidermis.

When magnified at 1000x, these particles look similar to magnified mud from a bottom of a pond.
