PPT-Chapter 4 - CELLS Cell Lab

For each prepared slide Draw each cell remember to draw the field of view and label any structures you know Record the magnification of each Make observations of the cells Include items such as color structures size etc. Hydrogenpowered fuel cells are not only pollutionfree but also can have more than two times the e57375ciency of traditional combustion technologies WLRQ5735957347KGURJHQ57347JDV5734757536RZV57347WKURXJK57347FKDQ WKH57347FDWKRGH57361573477KLV57347575 Characterisation of novel anticancer drugs PART 2. Most currently used anticancer drugs work by targeting the cytoskeleton, cell cycle progression or the apoptotic machinery.. Tumor. resistance to anti-cancer drugs. Why Would A Cell Divide?. Growth. Repair. The Cell Cycle, Mitosis, and . Meiosis. New cells can only be made when existing cells divide. All cells have the ability to divide – but some cells lose this ability.. Why do cells need to divide?. Growth and development. You started as 1 cell and now you’re made up of roughly 40 TRILLION cells. Repair and regeneration of tissue. Reproduction. What happens when cells divide? . Just like people have phases of development,. Cells have phases too.. In somatic (body) cells, a parent cell produces 2 daughter cells.. The purpose of mitosis is for growth and repair of tissue.. Three Phases or Stages. Two Basic Types. Remember….cells are the basic unit of life for ALL living things.. There are two basic types of cells:. Prokaryotic cells . – found in bacteria. Eukaryotic cells . – found in . S. 2. , & volume is . S. 3. , where . S. = length of the side of the cube.) Which of the following cube-shaped cells would be most efficient in removing waste by diffusion?. Cells (Test . 1). 5. . S. 2. , & volume is . S. 3. , where . S. = length of the side of the cube.) Which of the following cube-shaped cells would be most efficient in removing waste by diffusion?. Cells (Test 1). 5. A pathogenic bacterium has been engulfed by a phagocytic cell as part of the nonspecific (innate) immune response. Which of the following illustrations best represents the response?. by tagging. Lesson Title, Essential Question, Objectives. Lesson Title-Cell . Structure and Function. E.Q.: Why is cellular transport important to the function of cell organelles?. Obj.: . Describe the relationship between the structure and function of the cell membrane; Differentiate between the processes of osmosis, diffusion, passive, and active transport; Review for test . Cells Homeostasis Cells work together to maintain homeostasis . Cells have different functions. Homeostasis = stable environment in your body; balance Your body maintains its homeostasis even if outside conditions are changing. Focus on Integrins. John Cooper.

Limits to Cell Growth. The larger a cell becomes, the more demands a cell places on its DNA. If extra copies of DNA are not made, an “information crisis” would occur. The cell also has more trouble moving nutrients and wastes across the cell membrane. Lecturer . Dr. Samah A. Jassam BSc MSc PhD . MRSB. Al-Mustansiriya University . Collage of Pharmacy.
