Mitosis
The different phases of mitosis shown in the timelapse are:
​
Interphase
Prophase
Metaphase
Metaphase
Anaphase
Telophase
Mitosis is regenerating in the process of splitting cells and regrowing. In mitosis, one cell has the ability to separate itself into two cells and continue the process of doubling until it has regenerated an entire limb. Through understanding mitosis, we can figure out how to replicate it in order to use regeneration in other things.
Plant Exhibition
Riley and my project for this exhibition is an end of the world food supply. We mainly based our project off of the assumption that the world would end by a flood via a rising water level.
Our research matters because floods are happening today. Because of global warming, the glaciers are melting, causing the water level to rise. This can mean disaster for cities living at the current water level elevation.
For a question posed in math, we decided to explain why sample size is important. We considered that in a black and red roulette if you bet on red for ten turns and you win 9 of those turns, no one would bat an eye. However, if a person were to win 90/100 of those red bets, a reasonable person would tell the management.
Sample size matters because a larger sample will always be more reliable in supporting a theory; more evidence will always be more evidence. Similarly, the more participants in a study, the more reliable the results will be. Would you trust a product that was tested on one person that turned out fine? There are too many variables that could have affected that one result. When you have more data points, you can take the average of those points and create a composed result that takes into account all of the information.
I wish we would have taken this into account during our project, because the way we executed it, our results, as little as they were, were not reliable.
photosynthesis lab
The purpose of this experiment was to witness the real-time effect of photosynthesis by putting carbon dioxide into a leaf, making it sink in water, and watching as it eventually floats up because of the oxygen it converted from water, carbon dioxide, and a light source.
Our results showed that photosynthesis is not instantaneous and that it takes more than twenty minutes to create oxygen out of other materials for a 1 cm in diameter leaf disk.
Monocot vs dicot
The purpose of this experiment is to discover more evidence towards which is a monocot and which is a dicot. Based on my findings, I believe that the mung bean is a monocot and the corn is a dicot.
DAY 1
Before this point, I looked under the microscope and found that the seed coating on the mung bean followed the same pattern that identifies monocots.
Observations:
The corn split a little at the bottom and the mung bean's seed coating split and peeled off a little.
