Biology
Unit 3:  Cells & Cell Structures
UNIT SUMMARY  

Scientists have created the cell theory which explains that the cell is the smallest unit of matter that can carry out all of the processes of life. Most cells are no larger than 10-50um in diameter. They come in a variety of shapes and sizes determined by the function of each cell. Some are simple, some complex, some are part of single-celled organisms; some are part of multi-cellular organisms. Cell structure and composition varies from kingdom to kingdom. All cells must have a few basic components. Many membranes divide cells into compartments (organelles) that have specific functions, much like our organs have specific functions.  
Objective:  Relate cell parts/organelles (plasma membrane, nuclear envelope, nucleus, nucleolus, cytoplasm, mitochnodrion, endoplasmic reticulum, Golgi apparatus, lysosome, ribosome, vacuole, cell wall, chloroplast, cytoskeleton, centriole, cilium, flagellum, pseudopod) to their functions.    Std. 2.1
Objective:  Compare and contrast, at the cellular level, the general structures and degrees of complexity of prokaryotes and eukaryotes.     Std. 2.2
Objective:  Use cellular evidence (cell structure, cell number, cell reproduction) and modes of nutrition to describe the six kingdoms (Archaebacteria, Eubacteria, Protista, Fungi, Plantae, Animalia).     Std. 2.3  
Objective:  Compare and contrast a virus and a cell in terms of genetic material and reproduction      Std. 2.8

Objective:  Explain the role of cell membranes as a highly selective barrier. (diffusion, osmosis, facilitated diffusion, active transport)     Std. 2.1
