1. A microscope is an instrument that magnifies a specimen
2. A specimen is the object being observed under a microscope
3. The eyepiece is the lens where the observer looks into.
4. The objectives are the lenses in the rotating nosepiece
5. The specimen is placed on the stage
6. The diaphragm controls the light going into the slide
7. Objects being observed are placed on a slide
8. The slide is a piece of glass that that holds the specimen
9. A cover slip covers the specimen on the slide
10. The magnification of a microscope is the product of the power of the eyepiece and the power of the objective.
11. An animal cell is covered by a cell membrane
12. An animal cell is composed of the cell membrane and the protoplasm
13. The protoplasm is composed of the cytoplasm and the nucleus of the cell
14. A plant cell is covered by the cell wall
15. The cell wall is composed of cellulose
16. Plant cells contain chloroplast
17. Chloroplast contains chlorophyll
18. Chlorophyll is makes food for the plants
19. Plants are producers and they make their own food
20. Plants make food in the form of glucose
21. Unicellular organisms are simply and they are composed of only one cell
22. Multicellular organisms are more complex and are composed of multiple cells
23. Euglena, amoeba, paramecium, and yeast are examples of unicellular organisms
24. Humans, snakes, birds, and frogs are examples of multicellular organisms
25. Diffusion is the movement of particles from an area of high concentration to an area of lower concentration.
26. An area of high concentration has more particles while an area of low concentration has lesser particles.
27. Osmosis is the movement of water through a membrane
28. Diffusion is fastest in gases and is slowest in solids.
29. When there is an equal amount of salt and water inside and outside the cell, water will not move in or out of the cell.
30. When there is more salt inside the cell than outside, water will move into the cell and the cell will expand.
31. When there is more salt outside the cell than inside, the water in the cell will flow out and the cell will shrink.
