Cell Division, Chromosomes, and Inheritance Worksheet Complete all four sections of this worksheet. Section I: Mitosis and Meiosis Part 1: Review the following images on mitosis and meiosis. [pic][pic][pic][pic][pic][pic] [pic] Part 2: Explain the events you observe in the pictures. The top picture is mitosis. The phases listed in order from left to right are: interphase, prophase, prometaphase, metaphase, anaphase, and telophase. During interphase the DNA is replicated

Similarly, a cell has a life cycle.After reading pages 164 – 165 in your textbook, outline the six stages of the cycle of a cell. | 10 points | Answer:1. Interphase- when the cell is going about regular activities 2. Prophase- when the DNA chromosomes first become visible 3. Metaphase- When the chromos line up in the middle 4. Anaphase- when the chromos form pairs and are apart 5. Cytokinesis- when the cell has two separate nuclei and is about to split into two different cells | Part 2: The

Labset Two Worksheet 1. What is differential staining? How does it differ from simple staining? (2) Differential staining uses more than one chemical stain. It can help differentiate between different microorganisms, or different parts of the cell. The simple stain uses one stain and is used to see cell shape and size. 2. What are the differences between gram positive and gram negative cell walls? (2) A gram positive has a thick wall of peptidoglycan and stains purple. A gram negative

stem cells...are in effect, a human self-repair kit," (Christopher Reeve, activist – Larry King show). For the advancement of science, stem cells are infinitely valuable, especially when considering all the potential applications in the field of medicine. Stem cells usage is a very controversial topic, because most people think of abortions, cloning, and other negative topics when they here the term stem cells. However I think those thoughts are because they don't understand what a stem cell is, where

differences between the two processes: Mitosis is a form of cellular reproduction in which the parent cell divides, giving rise to two daughter cells that are genetically identical to each other and to the parent cell. Mitosis does not involve combining genetic information from two different parents; hence, it is a form of asexual cellular reproduction. It occurs when an organism grows, or when damaged or worn cells are replaced. Many unicellular organisms reproduce asexually by mitosis, as well. Meiosis and

Plant Cell (Photosynthesis) versus Solar Cell Regina D. Parker October 31, 2010 Three ways a plant cell and solar cell are similar and different to each other is that plant cells and solar cells both convert sunlight into energy. In the case of plants it is chemical energy for solar cell; it is electricity. Plants use organic processes but solar cells use inorganic semiconductors.[i] Plant cells are different from the cells of most other organisms. Plant cells are

Carrier Proteins and Active Membrane Transport The process by which a carrier protein transfers a solute molecule across the lipid bilayer resembles anenzyme-substrate reaction, and in many ways carriers behave like enzymes. In contrast to ordinary enzyme-substrate reactions, however, the transported solute is not covalently modified by the carrier protein, but instead is delivered unchanged to the other side of the membrane. Each type of carrier protein has one or more specific binding sites for
