Mitosis Mini Project
What is mitosis and when does it occur?
Mitosis is the process that occurs when the cells are splitting
What are the stages?
Interphase
Prophase
Prometaphase
Metaphase
Anaphase
Telophase
Cytokinesis
Interphase
How long do they last? You can explain what you learned about onion root mitosis.
Interphase lasts for 90% of the cells life whereas the process of mitosis only takes up 10%of the cells life span
How does this relate to the current research we are doing with planarians?
The planarians are actively using mitosis to regenerate their bodies. When they are injured this process appears to speed up so that they can heal faster.
How does understanding the process of mitosis help us tackle questions about human regeneration?
It gives us a greater insight Into how cells divide as well as being useful for making medical advances by testing the difference between our cells and the stem cells of animals that can regenerate and how this process works. He can also test medical advances on things that regenerate faster.

Plant - Mania Project
Abstract:
As you probably know, oxygen is required for life. So, we are looking at plants that produce more than 5 ml of oxygen per hour, or plants that produce more than 240 ml of oxygen in one day (24 hours). Our goal is to find which plant out the of selected high oxygen plants produces more oxygen than the average plant, to test which of the four plants produces the most oxygen. In our research, we looked at the benefits of having plants indoors and the effects that high oxygen plants have on the environment around them. We also looked at the effects of indoor plants as a group.
Significance and broader impacts:
High oxygen plants not only produce high amounts of oxygen, which is useful for people with difficulty breathing (like those with asthma), but plants that produce more than 240 ml of oxygen over 24 hours also tend to clean toxins out of the air. Some of them are formaldehyde, benzene, and carbon monoxide. Plants that clean the air could prove to be productive in places with higher levels of benzene, formaldehyde, and carbon monoxide in the air. NASA may be able to use these plants in the future for planets with toxic air and/or low oxygen levels. Oxygen levels also tend to improve humans’ psychology. The provision of extra oxygen in space also helps with cognitive functioning and mental health⁴’¹⁰. Plants, therefore, have a positive effect on the psychology of humans, which may help those with mental illnesses, such as depression and anxiety.

Exhibition Question
Why didn’t your methods allow for productive data collection?
X² This symbol is Chi-Squared. It is a mathematical term used to find probability and is often found when comparing statistics. To perform a X² math problem, you need at least twenty points of correlating data. If there are less than twenty points of comparable data the results will be skewed. The point of this formula is to accurately depict the expected probability if you were to consistently test. X² can also be used to compare different data results as long as there are the same amount of data points to compare. Unfortunately, our group was unable to use X² on our data because we didn’t have enough data points to test with either of the plants that we studied.
The main restriction of our project was our time limit. Ideally, we would have needed 40 days to get our full and accurate data collection. In the end, we were only able to have 13 days of data collection. Why we were only able to get 13 days of data was mostly because we spent a lot of our time planning the entire project and refining it the best we could. During our testing period, we could only allow one plant to be in the oxygen chamber at once. This limited us because it made out process fairly slow, and the plants had the be in the chamber for 24 hours at a time total.
After we tested the spider plants multiple times, we started testing aloe plants to collect data on their oxygen levels. We also needed to do this to compare the differences between the oxygen levels of each plant. After we started collecting data on the aloe, we realized that they were starting to die when we put them in the oxygen chamber. The container was too small and there wasn’t enough room for the aloe to fit in the chamber, even if it was just for a day. We collected data for three days on the aloe plants which was not enough. Luckily, we collected multiple runs of data for the spider plants, but that still isn’t enough information to conduct any conclusions on. If we ended up doing this project again or continuing it, we would get more plants of a different species (like heartleaf philodendrons as we had originally planned) and test their oxygen levels as well.
Refinement
If I were to reduce this project and change some things I would have taken better care of the plants outside of the chamber. There were many variables that I feel we didn't account for when the plants were out of the chamber they weren't on a watering schedule or put into the same spaces so they could have been under stress that we didn't calculate into our experiment, or regard when looking at our final information. The reason that I would do this differently would be to get more precise calculations. It would also be an interesting experiment to compare the two separate tests to understand him much this can change a result.
Photosynthesis Interactive
The point of the experiment.
Through this experiment, we started this process by learning about photosynthesis. this process takes three main materials carbon dioxide, sunlight, water this then creates Glucose and sugar. the plant takes the Glucose and converts this into energy the plant need to live and grow. this process is shown in the diagram below. We're able to compare the effects of photosynthesis when the leaves are exposed to different forms of light. We learned how to fallow a lab write up as well as compare and record data in a scientific way.
Interpretation of your results
Through this process, I was unable to get varying results. I punched out six leave pieces and placed them into about three centimeters of water under white lite. I recorded the leaves for an hour before determining that the leaves weren't going to rise. I noticed that although my leaves didn't rise the two that were next to mine but in the .... solution did rise.
Graph of my findings
Mini-Experiment Monocots vs. Dicots
Purpose of the Experiment: This project was about growing different types of plants and having the knowledge to understand whether or not they are classified as a Dicot or a Monocot. we did this over the course of several days recording the times that evidence showed up on the two plants and what that evidence proves about the two different plant types. We did this by looking at the plant's roots leave the structure and some people even looked into their nutrients absorption.
Prediction: These observations I had concerning the cotyledon lead me to believe that the corn is the Monocot and that the bean is there for the Dicot. By day two It’s hard to identify other traits of the monocot and dicot, they haven’t developed a stable root stem, leaves, or flowers. The only indication we have is the cotyledon that we indicated on day one.

Experiment Observations
Monocot and Dicots Experiment
Observations
Materials: clear plastic cup, corn, mung bean, and paper towels
Day One of Collecting Data
-
The mung bean has a green outer shell on it and on the inside its a white color
-
They have a stem or root looking attachment that's sticking off of them
-
They were probably about 3 to 2 times smaller than the corn
-
This seed spit directly in half and had a stem looking pice to it
-
-
The corn is a shriveled slightly bright yellow with brown details.
-
It was thin and had one end that was brown
-
The corn was hard to break in half and shattered it didn't have a stem looking part to it when splitting in half
-
-
Corn size
-
1.2 cm
-
-
Mung bean size
-
1 cm
-
.7 cm
-
1.1 cm
-
.8 cm
-
The observations I had concerning the cotyledon lead me to believe that the corn is the Monocot and that the bean is there for the Dicot.
Day Two of Collecting Data
-
Today the mung bean grew, even more, it has swelled and the cotyledon is reaching towards the base of the cup but hasn't reached it.
-
The bean appears to have two cotyledons so I still believe that it is the dicot.
-
-
The corn is grown twice as much
-
It's still has a smaller codaleadon than the bean.
-
I still believe that it only has one cotyledon.
-
-
I added 40 ml to the cup for the weekend.
-
I didn't get a chance to measure but they didn't appear to have a significant change in size
It’s hard to identify other traits of the monocot and dicot, they haven’t developed a stable root stem, leaves, flowers. The only indication we have is cotyledon and that's still hard to tell
Day Three of Collecting Data
-
The mung bean quadrupled in size today most of the cotyledon touching the base of the cup
-
They have also started producing chloroform and turning green
-
-
The corn has also grown a lot more over the week.
-
It is about the size of the mung bean
-
It also looks duller than it was the last time did observations before.
-
I watered all the plants today the paper towel was still damp so I gave them 30ml
Day four of Collecting Data
-
The mung been has grown longer one bean has died
-
The beans have started sprouting leaves
-
They have started sprouting other root branches and tributaries off of their main root system
-
-
The corn it longer than the mung bean root now.
-
It has a leave almost column looking structure now still too small to see individual veins in it
-
The root to the corn looks as though it has small hairs on it.
-
It has some smaller root extensions branching off of the main column l.
-
Watered the plants the paper towel was dry so I gave it water I didn't measure the water however but gave it enough to leave a small water will at the bottom of the cup.
A detailed outline of the experiment process.
On the first day of our experiment, we tried splitting the seeds, the bean split directly in half while the corn shattered. We then looked under a microscope at the cotyledon. By day three the main root structure has grown monumentally but it's hard to decipher what type of root system it is at this point since it has yet to branch off. On day four most of the Mung beans have grown leaves a more complex root system which is highlighted in my pictures. the corn although it doesn't show its leaves for the next day you can see its root system quite clearly in the slideshow of pictures. the live structure is quite clear in the pictures as a more net-like structure, and its roots looked like tap roots these are the indicators of a Dicot plant. the corn, however, has a root system that is more sporadic and goes a little wilder than the beans root. I also grow corn and new from personal experience and would soon be conferment when the corn leaves grew that they run parallel. these are the traits of a Monocot plant. this collected information proves that my previous Hypothesis what correct.
