Regeneration is when stem cells create needed body parts of an organism. Both starfish and lizards have this ability. Starfish can regrow their limbs if they are cut. Salamanders have this ability with their limbs and tails as well. Planaria regenerate more easily than other organisms which makes them more wanted for regeneration studies and experiments. Stem cells are key in this process to create lost body parts. Stem cells are cells in an organism's body that can play any part or become any part that is requested. This is common in babies for humans, but in others is completely natural to stay throughout the organism's lifetime. Our planaria were cut from two original planaria. We cut one into three parts and cut the other's head in half. We are still waiting to see the incredible results.
- Phloem & Xylem
Are Phloem and Xylem Similar? What are the Differences? Similarities: Phloem and xylem are tissues in a plant that transport food and water. Both are vascular tissues and when they work together to effectively transport food, water and minerals they form...
- Mitosis Vs ...
Mitosis can be compared to a couple of different cell actions. But what makes it different?Mitosis is the process of which a cell divides and creates copies of itself, the main purpose of this being to help the organism grow or to replace cells that are...
- Eukaryotic And Prokaryotic Cells
What are Eukaryotic and Prokaryotic cells??? They are the tiny little building blocks of life and sometimes death! Eukaryotic cells are what make up humans, animals, and plants. They do everything from constructing us as babies with DNA to making...
- # 39 The Need For Transport Systems In A Multicellular Organism
The transport system enables the rapid delivery of nutrients and O2 to as well as the removal of metabolic waste products (including CO2) from all cells of the body for survival. All cells need to take in substances from their...
- #31 Control Of Cell Division, Stem Cell, Haploid And Diploid Cells
Each cell contains genes that help to control when it divides. Cells divide by mitosis only when required. When receives signals from neighbouring cells, it responds by dividing or not dividing. If this control goes wrong, cells may not divide when they...
