Another week in science

This week in science class we discussed DNA and Mitosis related things. We took some notes on this stuff including:
-Chromosomes are packages of DNA.
-When DNA is unraveled, it is called a Chromatin
-Centrioles split
-Centrioles come from the Chromosomes
-Two Centrioles make up the Chromosome
-The Chromosomes move around and go to the center
-Organelles start to form and they double
-Centrioles produce Spindle Fibers
-Spindle Fibers connect to the Centromeres

Some inportant Mitosis terms include:
-Interphase
-Cytokinesis
-Chromatin
-Anaphase
-Metaphase
-Telaphase
-Chromatin
-Centromere
-Spindle Fibers
-Pro Metaphase
-Chromosome
-Centriole
-Centrosome
-Mitosis
-Cell Reproduction
-DNA
-Asexual
-Daughter Cell
-Parent Cell
-Nucleic Membrane
-Prophase

We made a concept map as well. Mitosis is in the middle and is the center of everything. Prometaphase, Prophase, Telaphase, Interphase, Cytokinesis, Anaphase, Metaphase and Asexual all come off of Mitosis. Parent Cell comes off of Interphase, Spindle Fibers come off of Prometaphase, DNA Replication comes off of Prophase, and Cell Reproduction comes off of Asexual. Daughter Cell comes off of Parent Cell, DNA comes off of DNA Replication and Centrosome comes off of Spindle Fibers. Chromosome comes off of DNA, Chromatid comes off of Chromosome, Centromere comes off of Chromatid and these two combine.

So that's it for this week's blog... See yah next week (:

This week in science

This week in science class we discussed reproduction and DNA. We learned that cells come from other cells. The cells split. Most of them are asexual. This means that it doesn't need another cell for reproduction. There is an egg cell which comes from females and a sperm cell that comes from males. These cells must combine to make a new type of cell. No cells are exactly the same. You look different from your parents because it is coming from two different organisms. Some words for this are DNA, gene, protein, chromosome, mRNA and codon.

Um. Yeah.

Okay so hey. This week in science we talked about science related stuff. You know. We talked about transformation of energy. We said how we need plants to live. Plants get energy from the sun. Animals eat plants, and then the energy is transferred from the plant to the animal. Then humans eat the animals. The energy transfers about 10% of it every time. So you would get more of it if you ate the plants themself.


Peace out.

This week in Science we did...

This week in fa-fa-fa Fins' class we talked about cells and DNA. A cell is made from Atoms, which are made into molecules, which are made into Macromolecules (chains), which turns into Organelles, then that turns into many Organelles, which turns into one cell and then tissue, then organs, then it makes an organ system, which makes many organ systems which FINALLY turns into a Complex Organism. DNA is what makes you an individual and it makes you and people in your family look alike.
