Signal Proteins for Plant Stem Cell Discovered

• The cells communicate with one another via the transportation of a protein

• Meristems are the key to plant growth

• Embryogenesis is the process by which the embryo is formed after fertilization\

• Arabidopsis - the genes which are activated by Menopteros

•Signal transmitted by the surrounding cells to form the hypophysis is a protein

•How do plant cells in the young embryo know what they have to become?

•The nearby cells tell them by sending a gene activator

•This communication makes sure that the meristems are at the right places, to enable stem cells to form roots at these places

Reflection:

I used an article on plant cells because we studied the difference between animal and plant cells in class. We drew diagrams and labeled each part of the cell. This article was interesting because I learned how plant growth is affected by the process of Embryogenesis. I didn’t know that plants realize what they have to become and this article did a great job informing me!
