Mitosis: The division of a cell that results in two exactly identical cells. 5 Stages of Mitosis:
Interphase- The cell is involved in metabolic activity and performs it's duty as part of a tissue. (18-20 hrs)
Prophase- Chromatin in the nucleus begin to condense and become visible as chromosomes. The nuclear membrane disolves morking the begging of prometaphase. (2&1/2 hrs)
Metaphase- Spindle fibers align the chromosomes along the middle of the cells nucleus. (2 hrs)
Anaphase- The paired chromosomes seperate at kinetochores and move to opposite sides of the cell. (1&1/2 hrs)
Telophase- New membranes form around the daughter nuclei while the chromosomes disperse and are no longer visible. (1 hr)
Planarians can split themselves in half when threatened, but we cut them which should cause them to grow into a new identical planarian. The process of mitosis is important for human regeneration because once we fully understand it maybe we will be able to combine it with other materials so humans can regenerate.Interphase: The cell is involved in metabolic activity and preforms it's duty as part of a tissue. Prophase: Chromatin in the nucleus begin to condense and become visible as chromosomes. The nuclear membrane dissolves marking the beginning of prometaphase.

Telophase: New membranes from around the daughter nuclei while the chromosomes disperse and are no longer visible.
Growing Plants With Music
Abstract: My project will investigate if music helps plants grow faster and/ or larger. Many experiments have been made to demonstrate the reactions plants have to different sounds and vibrations. Although plants usually hear and feel different animal vibrations in nature, maybe different styles of music will affect them in a positive or negative way. My experiment will use different styles of music to demonstrate whether or not plants are affected by music.
Significance: Plants are responsive to vibrations. Some studies have found that music increases biomass up to 20 percent 3 and doubling growth rates 4. Although we are not sure the mechanisms that affects plant growth, testing how different types of music affects plants growth is a cornerstone to investigating this field. Most researchers use classical music so we are unsure about how other genres will impact plant growth.
Reflection: My plants died before they were done growing because I accidentally left them at school over winter break so they dried out and froze. If I were to do this project again I would spend more time creating my planting pot and find better environments for my plants to grow in. My plants in my experimental group were supposed to be exposed to music while they grew but being at school enabled me to play music for them most of the time. I feel that my experiment was unsuccessful because I couldn’t see a difference in the plant growth. I believe it was due to the lack of music and cold weather that enabled me to record accurate results.
Photosynthesis Interactive Lab
Purpose of Experiment: We did this photosynthesis lab in order to learn how leaves transform carbon products into oxygen products during the process of photosynthesis. Results: All ten of mt leaf disks were floating by 15 min under the white light.
Monocots vs. Dicots
Purpose of Experiment: We did this experiment in order to further our understanding of the difference between monoco's and dicots by growing mung beans and corn.
Predictions: I predicted the mung bean was a monocot and corn a dicot. When I observed the mung bean I noticed that it split evenly apart which led me to believe it has two cotyledons. Corn on the other hand shattered in many different pieces leading me to believe it has only one cotyledon.
Observations: Over the course of this experiment I noticed my mung bean sprouted before my corn and more than my corn. The corn sprouted from the bottom and the mung bean sprouted from the middle.
Findings: I found that corn is a dicot and mung beans are monocots. I realized this when I seen my peers leafs on their plants the corn had parallel veins throughout the leaves and web veins in the mung bean leaves.
Limitations/Changes: The first day I watered my plants with water from summers house, then I started watering my plants with water from Animas High School I put once I put a couple sprays of cleaning chemicals they died.
