http://whybecausescience.com/tag/funny-science// Entry Task 1. What is the difference between prokaryotes and eukaryotes? 2. What are the differences between plant and animal cells? 3. What is the differences between atoms and cells? 4. What is the difference between diffusion and osmosis? 5. What is the difference between active and passive transport? 6. What is selective permeability? Definitions Eukaryotes Prokaryotes Plant Cells Animal Cells Organelles Lipids Carbohydrates Nucleic Acids Proteins Cell Membrane Macromolecules Diffusion Selective Permeability Osmosis Active transport Passive transport What are the different criteria for life? 1. 2. 3. 4. 5. 6. Living things are composed of cells Living things obtain and use energy Living things grow and develop Living things reproduce. Living things respond to their environment. Living things adapt to their environment. Atoms Vs. Cells Atoms: basic building block of all matter. can’t see individual atoms with a magnifying glass or even a powerful optical microscope. Cells: basic building block of life smallest unit of life that can replicate independently made up of many atoms grouped into molecules. can be seen with microscopes What is an organism? an organism is any living system (such as animal, plant, fungus, or micro-organism). all organisms are capable of response to stimuli, reproduction, growth and development may either be single-celled or multi-cellular multicellular (many-celled) describes any organism made up of more than one cell Single Cell/Many Cells/Not a Cell? Chicken egg Single Cell: technically the cell is the tiny spot you can sometimes see on an egg yolk, as small as it is it’s still larger than most cells. The rest of the egg provides life support that would be necessary if the egg had been fertilized http://www.forumazur.com/images/stories/HouseGarden/Animals/Chicken/ChickenEggs.JPG Single Cell/Many Cells/Not a Cell? Water Not a Cell: water is a polar molecule composed of hydrogen and oxygen atoms http://www.admc.hct.ac.ae/hd1/english/probsoln/water.jpg Single Cell/Many Cells/Not a Cell? Tree bark Many Cells: Many plant cells combined to create the bark of a tree http://www.bing.com/images/search?q=tree+bark&qpvt=tree+bark&FORM=IGRE&adlt=strict#view=detail&id=8186A05986 782BF7C2EEDA13860B24B06360808E&selectedIndex=98 Single Cell/Many Cells/Not a Cell? Amoeba Single Cell: an amoeba is a single celled organism. Amoeba is Protozoa that consists of unicellular organisms which do not have a definite shape http://dpgitr7uxxopj.cloudfront.net/wp-content/uploads/amoeba-2695978355.jpg Single Cell/Many Cells/Not a Cell? Bacterium (plural is bacteria) Single Cell http://www.fallingpixel.com/products/6035/mains/bacteria.jpg Single Cell/Many Cells/Not a Cell? Human egg Single Cell The egg cell is the largest human cell. http://www.paranormalstories.com/images/bieggsperm2.jpg http://pictures.funny16.com/wp-content/uploads/2011/12/human-eggs.jpg Single Cell/Many Cells/Not a Cell? Virus Not a Cell: Not a Cell: Living cells can extract energy from their environment. Viruses have no metabolic capacity of their own, but rely the host cell for all functions http://www.bioquellus.com/interface/assets/images/content/Influenza_virus_2008765.jpg Single Cell/Many Cells/Not a Cell? Sperm Single Cell The sperm cell is the smallest human cell. http://www.babyhopes.com/articles/wp-content/uploads/2008/08/sperm.jpg Single Cell/Many Cells/Not a Cell? Chloroplast Not a Cell: Not a Cell it is an organelle within a cell to help with cell functions http://4.bp.blogspot.com/-GLpOYsrH7HE/Tnp3h09i97I/AAAAAAAAAE8/QNlmlI1T9Qw/s1600/Chloroplast.jpg State Standards Standard 911-LS1C: Cells contain specialized parts for determining essential functions such as regulation of cellular activities, energy capture and release, formation of proteins, waste disposal, the transfer of information, and movement Students Expected to: Draw, label, and describe the functions of components of essential structures within cells (e.g., cellular membrane, nucleus, chromosome, chloroplast, mitochondrion, ribosome) What does it mean?

Students expected to: Describe the structure of the cell membrane and how the membrane regulates the flow of materials into and out of the cell. What does it mean?
