 * All about Cells**

 Three Choices: Write a newspaper article about organelles in cells. Design a Shirt that tells the different functions of organelles. List the organelles and their functions.
 * __Organelle Function Activity__** (Use SNB page 83)

Example newspaper article: __Cell Goes Crazy__ On Friday Dec. 16th a cell went crazy. The nucleus which controls the cell’s activities directed too many steroids to be made on the endoplasmic reticulum. The ER then transported the steroids to the Golgi body for packaging and export out of the cell. The lysosomes and vacuoles tried in vain to keep homeostasis. The lysosomes used digestive proteins made by the ribosomes to breakdown the steroids using chemical reactions. The vacuoles stored as many steroids as possible. The cell membrane was still overwhelmed and let the steroids out into the blood stream causing a roid rage in the organism. The mitochondria liked all the action, so it kept producing energy from carbohydrates. Fed by this energy the craziness continued until the police arrived and tazed the organism. Steroid production is a natural cell function, so no arrest was made. (Note the functions of the organelles in the above article.)

Because of this cells are …… .  8. …… is the main method by which small molecules move across the cell membrane.  __**Textbook Pages 104 & 105**__ (Use SNB page 80) Draw the figure of Diffusion on textbook pages 104.

This scientist discovered cell walls by observing cork with a 20x compound microscope that he made. He called the little boxes he saw cells and published his observations and drawings. (TB page 82)

This scientist discovered a few different kinds of cells, a few cell parts, and many microscopic organisms. The many powerful 266x simple microscopes he made greatly advanced what was known and founded the field of microbiology. (TB page 83)

This scientist studied plant cells and made one of the first generalizations about cells. He wrote that cells are the basic building blocks of plants. In other words, all plants are composed of cells. (TB page 84)

This scientist studied animal cells and stated that all organisms are made of one or more cells. He also formalized the idea that cells are the basic units of structure and function in living things. (TB page 84)

This scientist studied cells, tissues, and diseased tissues of both plant and animals cells. He stated that new cells only come from cells that already exist. This contradicted the idea that cells could arise from nonliving matter. (TB page 84)  Part 2 (Use SNB page 76 and textbook page 85) In multicellular organisms, cells are often organized into tissues, organs, and organ systems. Describe these three levels. more...

 * Points List**

 10/31 (Write notes Cornell style on SNB pages 47 & 48) 1 Rainbows form because light is being refracted or bent through raindrops which act as a prism. 2 Light is either reflected, transmitted, or absorbed when it strikes an object. 3 Transparent = material that transmits most of the light that strikes it 4 Translucent = material which scatters light as it passes through 5 Opaque = material which reflects or absorbs all of the light that strikes it; the color of an opaque object is the color of light it reflects 6 Pigment = colored substances that are used to color other materials; pigments absorb some colors and reflect others 7 Reflection = waves bouncing back off a surface through which it cannot pass 8 The law of reflection states that the angle of incidence equals the angle of reflection 9 Plane mirror = a flat sheet of glass that has a smooth, silver-colored coating on one side; the coating reflects light forming a virtual image 10 Types of mirrors: Convex = surface curves outward Concave = surface curves inward 11 Refraction = the bending of light waves due to a change in speed 12 Lens = a curved piece of glass or other transparent material that refracts light 13 Convex lens = thicker in the center than at the edges; light rays converge as they pass through 14 Concave lens = thinner in the center than at the edges; light rays bend away or diverge.
