PPT-Cells: The Basic Units of Life & the Cell in Action

1 Things that have ALL the characteristics of life are called what ORGANISMS All living things are organized grow amp develop reproduce respond maintain certain internal conditions amp use energy. Unit 1 – Introduction to Physics. Vocabulary. Physical quantities mass force. Current unit SI units. International system kilogram second. Basic quantities meter ampere. Derived quantities Kelvin mole. Cell. Regarded as the basic structural and functional unit of life.. Cell is a mass of cytoplasm enclosed by a plasma membrane consisting of certain organelles besides the nucleus or nuclear material, capable of self replicating.. Lesson 4: Describing Cells. Classify specialised cells as animal cells or plant cells.. Describe different specialised animal cells and plant cells.. Explain the structure and function of specialised cells using models.. O. R. G. A. N. I. Z. A. T. I. O. N. . O. F. L. I. F. E. Cells. Every living thing has at least one cell. . . Some have only one and some have trillions.. Most cells are too tiny to be seen without a microscope.. Basic Vocabulary. Biology -The study of living things. Biotic -A living organism. Abiotic -A non-living organism. How were cells discovered?. Robert -used the first microscope to view Hooke thinly sliced cork cells. . homeostasis. . Cells have different functions.. Homeostasis = stable environment in your body; balance. Your body maintains its homeostasis even if outside conditions are changing. . Levels of Organization. Cell membrane is like the doors on a car. They regulate what goes in/out.. The cell wall in a plant cell is like the frame on a car. The frame supports the car as the cell wall supports the plant.. The endoplasmic reticulum is like the fuel lines on a car. It lets a passage way for fuel to flow like proteins do in the endoplasmic reticulum . Focus on Integrins. John Cooper.

Tissue culture is the general name for the removal of cells, tissues or organs from an animal or plant and their subsequent placement into artificial environment conductive to growth. This environment usually consists of a suitable glass or plastic culture vessel containing a liquid or semi-solid support medium that supplies the nutrients essential for survival and growth. iPS. cells, self-renewal, differentiation, pluripotent, multipotent, Inner cell mass, Nuclear transfer (Therapeutic cloning), Feeder cells, LIF, embryoid body.. What are stem cells?. Cells that are able to renew themselves (. Identify and restate what the phases of the eukaryotic cell cycle are.. Restate what happens in each stage of the cycle.. Vocabulary. Cell . cycle. Interphase. Mitosis. Cytokinesis. Cells . Live in a Cycle. Chapters 12, 13, 16, 17. 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. The T-cell antigen receptor (TCR). The TCR is a complex of eight . transmembrane. proteins. The . خ± . and . خ² . chains form a disulfide-linked (. Sâ. €”S) dimer that is responsible for the recognition of antigenic peptides bound to class I and class II major . This theory . is . one . of the foundations . of . biology.. 2. Antonie . van. . Leeuwenhoek. The first man to witness . a . live cell . under a . microscope was Antonie . van . Leeuwenhoek, who .
