    I know exactly what you're thinking, "yo, this wikispace gangsta is totally not fly", well have I got news for you.
    What up, RNA time.

    What up, RNA time.
    Check it yo. RNA (ribonucleic acid) is a single stranded polynucleotide helix, similar to your homie DNA, 'cept with only one strand. Also RNA doesn't contain the thymine nucleotide, instead it has uracil, which is pretty dope too. Also RNA contains the ribose sugar, unlike it's bro DNA which has the sugar dioxyribose. Both RNA and DNA are polymers of nucleotides and are nucleic acids, dog. Feel me? Just so you know what up, nucleotides are comprised of sugar, phosphate, and nitrogen base. The smokin' graphic on the left illustrates for y'all the chemical structure of each nucleotide.

    There three different types of RNA and each is equally illin'.
    First off, mRNA. mRNA, or messanger RNA, is an uncoiled chain that carries coding information from the nucleus to the ribosome. The bangin' process by which mRNA picks up choice info is known as "transcription", y'all straight? I popped in a wicked gnarly vid down at the bottom of the page. For more info, check this interactive animation this website.
    Another type of RNA is tRNA, transfer RNA. It's nucleotides aranged in a cloverleaf pattern. It's job is hecka important, it totally transfers the code in codons to make animo acids. This process is called translation.

    Hypertonic: the concentration of solute inside the cell is less than outside the cell; the cell shrinks
    Hypotonic: the concentration of solute inside the cell is greater than outside the cell; the cell expands
    The way you can remember this is,To break it down, if there
    because there is a lower concentration outside, so the cell shrinks. If there is a greater amount of water outside the cell, water molecules
    will enter the cell, where there is a lower concentration, causing the cell to expand.

    Active Transport: When molecules move across the plasma membrane from an area of lower concentration to higher concentration,
    requiring cells to use energy.

    Phagocytosis: vesicles contain large particles or cells (cell eating)
    Here's an animation of active transport.

    1) All living things are composed of one or more cells
    2) Cells are the basic units of structure and function in all living things
    3) All cells come from preexisting cells

    Observed cork cells (plant cells)
    Looked like the small cells, or boxes, that monks lived in, hence the name "cell"
    Cell Diversity
    Shape - Diversity of the form of a cell reflects its function
    Size - Microscopic, unable to see with the naked eye

    Vocabulary:
    The Cell Wall is in plant cells only! It surrounds the cell membrane, and it's function is to help protect and support the cell.

    Cilia are short, hair-like extensions and on the cell that aid in cell movement.
    Flagella are long, hair-like extensions on a cell that helps the cell propel.
