Cells+Investigation

** U: image of few cheek cells. D: closer look at one specific cell. The cell can be determined as a animal cell since the cell is round and does not look like it has a cell wall. ** This is a close look at the stem of a plant. Along the middle seem to be long cells but they seem round so maybe it's water. On the side seem to be a different type of cell as it looks much more concentrated. ** U: Onion cells D: even closer look at the onion cells though these were dyed with eriochrome black T This is a close up that allowed us to see the nucleus dyed with eriochrome black T Single Nucleus shown also dyed with eriochrome black T
 * Cheek Cells
 * Plant Cell
 * Onion Cell

An interesting experiment was using salt water and pouring it on onion membrane.
 * Onion and Salt** - If salt water were to be poured on onion, the cell membranes and cell walls of onion cells would start splitting. No photo was taken though.


 * __Techniques for preparing slides and changing focus__**

Preparing a slide - wash the slide, and dry it - size does not mean better view of a slide - to add stains, just slightly let water flow over the edge, then drop the stain near the slide, on the other end use a tissue so that the water is soaked up and the stain will flow in

Changing focus - it is faster to get a good view by adjusting the focus back and forth - adjust with a wider range then narrow down - same for the objectives, work from not so close to closer.
