Lectopia requires login using your student number and unipass. These audio recordings appear in the course Moodle page. Due to the automated recording method, most lectures begin minutes into MP3 recordings and occasionally stop before the end of the lecture. Lecture PDF. I will spend some at the beginning of today's lecture introducing the course, its assessment, online support and content before giving you a brief introduction to the history of Cell Biology.

The structure and function of cells has now become a blend of basic research and clinical topics. The tools have also expanded with growth of molecular and analytical techniques.

Overview of cell signaling

Cells are the smallest working units of all living things. All cells come from preexisting cells through cell division. Eukaryotic Contain organelles surrounded by membranes Most living organisms Plant Animal.

Cell Membrane Outer membrane of cell that controls movement in and out of the cell Double layer. Nuclear Membrane Surrounds nucleus Made of two layers Openings allow material to enter and leave nucleus.

Endoplasmic Reticulum Moves materials around in cell Smooth type: lacks ribosomes Rough type pictured : ribosomes embedded in surface. Golgi Bodies Protein 'packaging plant' Move materials within the cell Move materials out of the cell. Lysosome Digestive 'plant' for proteins, fats, and carbohydrates Transports undigested material to cell membrane for removal Cell breaks down if lysosome explodes. Vacuoles Membrane-bound sacs for storage, digestion, and waste removal Contains water solution Help plants maintain shape.

Chloroplast Usually found in plant cells Contains green chlorophyll Where photosynthesis takes place.

Marine animals like crabs and sea stars are isotomic. The control of water balance is called osmoregulation. Isotomic means that the solutions have equal concentration. It helps it make sure that the cell wall isn't taking in to much. Plants cells loses water then it shrivels and finally its plasma membrane pulls away from the plasmolysis.

Although there isn't any trans fat, there is a lot of saturated and unsaturated fats. This can cause future heart and obesity problems if eaten in excess. Long-term effect. Nutrition Facts Contains trace amounts of Methyl Cellulose Chicken plants are horrible places where they abuse the chickens they use to make the dinosaur chicken nuggets, so don't eat them even if they are good.

Biology PowerPoint Krysten and Marina, p4 There's a lot of gross stuff in these nuggets but they taste good so there doesn't seem to be much of a problem, despite the long term effects. So the chicken is good tasting, eat it This food is probably worth eating Which is a chemical used in laxatives, which is really gross to have in chicken nuggets.

Short-term effect.

Tyson is not a good company, though! Extremely gross, processed chicken byproducts bones, tendons, skin, etc. Names The color gets lighter in very hot temperature. Open sandy desert washes Goetting, A. University of Michigan. Bobcat montana.

Interesting Fact The tail of the lizard looks like zebra stripes. Open areas Organism. Transcript: Regulating the Cell Cycle The cell cycle is regulated by a protein called "cyclin" because it regulates the cell cycle.

Cyclins were discovered during a similar experiment to this one. Step 1: A sample of cytoplasm is removed from a cell in mitosis.Introduction Cells vary considerable in size, shape, and function. The shape of cells in the body vary based on their function. Because cells vary so greatly in size, shape, content, and function, describing a typical cell is impossible. All of the structures described in the composite cell can NOT be found in every cell regardless of function.

Extremely thin and semipermeable. The cell membrane contains many kinds of proteins, each with a special function. Function: The membrane allows some substances to enter and leave the cell but not others, participates in signal transduction, and helps cells adhere to other cells. The membrane forms a boundary around the cellular contents, and the basic structure of the cell membrane is a lipid-protein bilayer.

Structure: The basic framework of the cell membrane consists of a bilayer double layer of phospholipid, with fatty acid tails turned in. Because of its hydrophilic nature, the head of a Phospholipid will orient itself so that it is as close as possible to water molecules.

The cytoplasm consists of a clear liquid called cytosol, a supportive cytoskeleton, and networks of membranes and organelles. Cell activities occur mainly in the cytoplasm, where nutrients are received, processed, and used. Network of protein filaments within some cells that helps the cell maintain its shape and is involved in many forms of cell movement. ER is made up of membrane-bounded flatten sacs and elongated canals. ER provides a tubular transport system inside the cell. Rough ER: Has ribosomes on its outer layer What does it function in the synthesis and transport of?

What does it function in the transport of? Internal membrane system in cells in which lipid components of the cell membrane are assembled and some proteins are modified. Function is protein synthesis. Small particle in the cell on which proteins are assembled; made of RNA and protein. Popeye is active because he eats spinach. However, for Popeye's cells to be active, his ribosomes help create proteins.

They are composed of about 6 flattened, membranous sacs. Function is to refine, package, and deliver proteins synthesized on ribosomes, and it packages the cells products. Vesicles that have a role in secretion are formed by the golgi apparatus and ER. Plays a central role in the transport of new molecules from inside to outside the cell.After you enable Flash, refresh this page and the presentation should play. Get the plugin now.
