Monday 10.4.10

10.4.2010 Today in Biology, we worked on two worksheets. On one we filled out chart on the many organelles. It was kind of like the one below. The columns were; the organelles function, which cell its found in, an analogy to a city and a sketch of the organelle.  example; | Vacuoles | both | stores materials | (picture) | Storage Places (P.O.D.) | The second worksheet, we had to draw a cell and label it.  TYPE OF ORGANELLE WHAT THEY DO: Cytoplasm- Hold parts of cell and nucleus together Nucleus Contains DNA Vacuole- Store Materials like water, salts, proteins, and carbs Lysosome- Break down lipids, carbs and proteins to go to other parts of the cell Cytoskeleton- Helps cell maintain its shape and is also involved with movement Centriole- Help organize cell division Ribosomes- Small particles of RNA, proteins are assembled there Endoplasmic Reticulum- Where lipid components of the cell membrane are assembled Golgi Apparatus- Modifies, sorts and packages proteins Chloroplast- Capture energy from the sun and convert it to food Mitochondrion- Convert chemical energy in food into compounds that are more important to cell use Cell Wall- Supporting layer to protect the cell Cell Membrane: Gives the sell a strong structure, allows things to come in and out of the cell Organelles that Store Clean Up and Support -Vacuoles -       Has vesicles that store and move cells to and from cells -Lysosomes -       Clean up crew -       Remove waste -Cytoskeleton -       Microfilaments; support the cell -       Microtubes; important with cell division Organelles That Build Proteins -Ribosomes -       Makes proteins -Endoplasmic Reticulum -       Have smooth and rough ET -Golgi Apparatus -       Gets proteins to the right places Organelles that Capture and Release Energy -Chloroplasts -       Same a solar plants -       Contain the green pigment chlorophyll -Mitocandria -       Have their own small DNA Cellular Boundaries -Cell Wall -       Animal cells do not have cell walls -       Nearly all of trees and stems are made up of cell wall material -Cell Membrane -       Has a lipid bilayer -       Allows some things to pass through and other things not the next scriber will be......
