Cells
Drawings vary, check to make sure the relative sizes are correct. High Power should show only a couple of cells that take up most of the viewing field. The micoscope is designed to view the slide at different spots, so not all drawings will look like this one. Images were snipped from the virtual microscope's flash animation. Scanning (4) | Low (10) | High (40) |
3. Go to google and type "cheek cells" into the search box. Click on "images" to see all the images google has found on the web showing cheek cells (there should be hundreds).
What do all of these images have in common? they are all irregular to round in shape, with a dark spot in the center
How do the cells vary from one picture to the next (how are they different)? colors vary depending on the kind of stain, size varies depending on magnification
4. Why are the google images of cells different colors? What is the natural color of a cheek cell? cells are stained for easier viewing, normally they are clear
5. Use the internet or your textbook to define or describe each of the following terms that relate to the cell. eukaryote - type of cell that has a nucleus nucleus - control center of the cell, contains the cell's genetic information cell membrane - the outer boundary of a cell cytoplasm - the fluid within a cell where organelles float
6. Keeping in mind that the mouth is the first site of chemical digestion in a human.Your saliva starts the process of breaking down the food you eat.Keeping this in mind, what organelle do you think would be the most numerous inside the cells of your mouth? (Hint: what organelle is responsible for breaking things down and digesting?) lysosomes
What is the movement of the chloroplasts in the hydrilla leaf cells? what its direction? and what process could account for the movement of the cytoplasm?
Clockwise movement. The lipotubuloids consisting of osmiophilic granules surrounded by a system of microtubules move from one place to another within a cell by
