Cell Structure and FunctionPearson's BioCoach Activity
This website is from the book producers Pearson's. It goes through the parts of the cells with a picture of each and a description of what it does. The Cell Starting Point This website is something I would use in an elementary classroom because it takes the parts of the cell and their functions and gives descriptions in their language for them to understand. Cell Functions Chart This is a chart of all the organelles in a cell and their functions. Along with this there is a picture of each and whether it is in an animal or plant cell. |
VideosThese are both youtube videos that are about the cells.
Cells Rap This is a sing-a-long rap with the lyrics and picture of cells on the screen. Crash Course This is a video of a crash course on the cell. The maker of these videos have many different subjects and videos covering almost everything! |

Blackboard Questions
1. What are every organism's basic requirements for life and the survival of its species?
Basic requirements for organism’s to survive are: food, water, shelter in their proper habitats, mates to reproduce and for most, air and sunlight. Every animal uses these elements but the way that they use them is what makes them different and unique to their environments.
2. If all organisms share these basic life requirements, why do organisms come in an infinite variety of forms? If we have the same life requirements, wouldn't it be most effective if we all looked and behaved the same?
Just because we all need the same basic requirements to survive doesn't mean that we all use them in the same manner. When we use these materials different ways we become different. For example, the pond creatures didn't need very much sunlight to survive and they can live happily in the water. For humans, we need the sunlight to survive more than they do. The sun produces our food and helps in other every day processes. Because we rely on sunlight so much, our eyesight is so much better than a pond creature that may just use the vibrations of the water to tell where an animal is. Also, we drink and use water to produce our food. We don’t need it to live in like the pond creatures we saw in class.
Everything on the plant uses these main materials for something else which causes diversity on the Earth. Because we have this diversity we are able to all live in harmony together. If all the organisms on Earth used the resources for the same reasons, we would not all able to survive like this. Since we use the resources differently, we also are able to produce different materials that others can use.
3. Contrast two pond water organisms you saw last week (or you could look up a couple, like a parmecium and an amoeba, for example). How are they the same in their form and function? How are they different?
Two creatures that we observed in our water sample were a water flea and a little worm. These two creatures are very different but they are similar because they both live in the same pond. These two animals did not have very much in common that we could see from the microscope. They both have different functions within the pond though. The water flea had a hard shell surrounding its body. The worm had a segmented body most likely used for movement. The worm also had little hairs at the end of its body that we suspect were used for movement. Having eyes in the front of the body of the worm made it easier for it to move through the water. Whereas the water flea had two little arms that were moving at a fast rate. We thought that this was for their movement also. The water flea also had eyes and the front of his body making it seems easier to move. On the water flea, it seemed like there were little antennas on top of its body which was different from the worm.
Another difference between the two was that even though the flea seemed to have a hard shell, the shell was pretty transparent. When we looked at it we could somewhat see what was going on inside of the flea.
Central Dogma
Genes that are made in the nucleus produce proteins. These proteins are transported out through the ribosomes that are on the endoplasmic reticulum. From there they go to the golgi appartus to get "tagged" for their job with in the cell and exit through a vacuole.
