whssweetfall2020 project 5

Project by group whssweetfall2020

Explore We know that plants give life to oxygen. Plants use it's roots to get minerals and water from the soil. In this project, we'll like to know why plants get sick and how people learn more about the diseases plants get. The cells that try to find and kill pathogens in vegetables are going to be tested in this experiment since soft rot is a big deal with vegetables being grown on the field and then dying out to this pathogen. A Pathogen is something comes from a disease and it harms the vegetables being grown.
Research Question What vegetable will have the fastest reaction? How will their appearances change over time. The pathogen is going to be in the bag for a while and until it is there for about a week, then we'll know when which vegetable it affects the most. We have three vegetables inside and based of what happens to one of the vegetables and which vegetable is the least harmed.
Predictions We believe that the potato and sweet potato will have similar reactions seeing as they have the same texture compared to the carrot. The carrot seems a little off and if it's DNA is different, then it might react or hold of the pathogen for a little longer. We will see how it goes and if the potatoes stay more alive then we'll now know which vegetable is different from one another. If one potato is still alive, then that potato must be verified as a specific type of potato because there are two types in the project. There is the sweet potato and the potato (regular), so yeah, we'll see what happens.
Experimental Design The independent variables are the potatoes and vegetables while the dependent variable is the soft rot and the control variable is the time you gave to experiment this. The independent variables are the vegetables because they are being exposed to a pathogen (which is a dependent variable) that is meant to change one of the variables in the week they are gonna be in the bag.
Conclusion Sweet potatoes look like they have something special in their immune system. It looks like cucumbers and regular potatoes don't have a strong immune system like sweet potatoes. The sweet potatoes are very nice coated with some but kicking cells or so, and this helps block out the pathogen, hands down.
