1. Cell Structure and Function Independent Organelles.
The objective of This study were
to study cells using stains and photography (Proscopes with hoox light microscopes).

2. Cheek cell’s have a nucleus and a cytoplasm and cell membrane.

3. Elodea the Cell wall protects the cell.
3 Images of Elodea
the Cell wall protects the cell.
Chloroplasts contain chlorophyll in the cell
which makes the cell appear green.

4. Paramecium
Large Nucleus
Small nucleus

5. MORE Paramecium

6. Rotifer

7. Nucleolus Nucleus with a nucleolus of an onion cell.
The nucleus controls all cell activites with DNA
The nucleolus is where RNA is made. RNA is DNA’s messenger
Nucleolus
Onion cell nucleolus this is the site where the RNA is produced.
Diffusion is the movement of molecules from a high to low concentration.
Here water diffused across the membrane to the outside of the cell.The salt caused a lower concentration of water outside the cell. Diffusion of water is called osmosis
Salt water onion has osmosis because water exits the
cell.

9. Cell Membrane Function
Iodine with starch

Dialysis tubing cell model
Click to add notes!!!!!!!!
The membrane is semipermeable.
Starch remains inside but iodine diffuses across.
