Cycling of Matter in Living Systems
Nature of ScienceTeachableThe fundamental unit of life, the cell, is an example of an efficient open system comprised of a cell membrane and organelles that carry out the basic functions of all living organisms. Students will learn that technological advancements in microscopy have enhanced the study of cells and cellular processes.
Focusing questions
- How did the cell theory replace the concept of "spontaneous generation" and revolutionize the study of life sciences?
- How do single-celled organisms carry out life functions?
- How do plants use specialized cells and processes to accomplish the same functions as a single cell, but on a larger scale?
- How does imaging technology further our understanding of the structure and function of cells?
Key concepts (POS)
- microscopy and the emergence of cell theory
- cellular structures and functions, and technological applications
- active and passive transport of matter
- relationship between cell size and shape, and surface area to volume ratio
- use of explanatory and visual models in science
- cell specialization in multicellular organisms; i.e., plants
- mechanisms of transport, gas exchange, and environmental response in multicellular organisms; i.e., plants
