Scientists have discovered that plant roots can sense UV-B light and have identified a specific gene that is a vital player in UV-B signaling, the communication between cells.
A study published Dec. 8 in the Early Edition of PNAS reveals that the gene RUS1 measures UV-B light levels and passes this information on to other parts [...]
You have learned about various body systems. Explain how cells aid in the development of the organism. Name three body systems and illustrate how they work together for a developed function in the human body. What would occur if the protein channels in the cell membranes became blocked and diffusion of particles that are intended to [...]
What are the differences between prokaryotic and eukaryotic cells. What did the yogurt look like when observed under the microscope. How do you think the size will compare to animal cells? What are the major differnces between the plant and animal cells? Are your cells in your body working? How do you know?
In 1492 Columbus sails to America. In 1879 Edison invented the electric lightbulb. Research and list information for five major cell discoveries beteen 1492 an d1879. How did these discoveries benefit some of the technologies that we use today. Explain your response. Since you are young scientists in the making, what are you interested in discovering [...]
MIT engineers have developed carbon nanotubes into sensors for cancer drugs and other DNA-damaging agents inside living cells.
The sensors, made of carbon nanotubes wrapped in DNA, can detect chemotherapy drugs such as cisplatin as well as environmental toxins and free radicals that damage DNA.
“We’ve made a sensor that can be placed in living cells, healthy [...]
All single-celled organisms are not alike. Or are they?
A Northwestern University study has found a surprising similarity among four quite different organisms. The simplest organism, a bacterium called H. pylori, uses the same number of biochemical reactions (around 300) as yeast, the largest, most complex organism of the group, when optimizing growth.
How can I assist you on the science fair project. I will checking my website throughout the break so that I may answer any questions you may have. I adore you all and hope that each of you have a very merry and wonderful holiday.

A certain virus attackes the mitochondria in cells. What would happen to a cell if all the mitochondria were destroyed?
Explain the ways plant and animal cells differ. The golgi complex packages and distributes proteins throughout the cells. The membrane pinches off vesicles and sends proteins around the cell and out of the cell. How does the Glogi and ER differ in appearance.
You created cell models in 3-D. Are cells flat of round? How is the cell membrane similar to a screen window? How did the cytoplasm in the cell compare to us observing Jello-o in class with the lights off?
