MS-LS1-2 Develop and use a model to describe the function of a cell as a whole and ways parts of cells contribute to the function. (Edible model + different cell types; boundary: nucleus, mitochondria, etc.) 

MS-LS1-3 Use argument supported by evidence for how the body is a system of interacting subsystems composed of groups of cells. (NGSS evaluation focuses on animal systems).

College Board (National) Grades 6-8

• There are many types of cells. Organisms may consist of one cell or many different numbers and types of cells. • Most cells are so small that the cells themselves and their details can be seen only with a microscope. 

LSM-PE.2.1.4   Construct a scaled model, based on measurements and estimates made using a microscope (when possible), that represents the relative sizes of a molecule, a bacterial cell, an animal cell and a virus. 

LSM-PE.2.1.1 Give examples of organisms that are made of one cell (both non-nucleated and nucleated) and organisms that are made of many cells. Compare and contrast the essential functions occurring in the single-cell organisms and in the cells of multicellular organisms. 

Objective LS.2.1

Cell Function

Students understand that cells perform the essential functions of life, such as energy transfer and transformation, exchange of gas, disposal of waste, growth, reproduction, and interaction with the environment.

[BOUNDARY: The following cell components — nucleus, mitochondria, chloroplast, ribosome, plasma membrane, vacuole and lysosome— are appropriate for students in grades 6–8. Emphasis should be placed on the function and coordination of these components, as well as on their role in the overall cell function, before introducing and reinforcing the names of these components.

LSM-PE.2.2.1  Describe, based on observations of cells made using a microscope and on information gathered from print and electronic resources, the internal structures (and the functions of these structures) of different cell types (e.g., amoeba, fungi, plant root, plant leaf, animal muscle, animal skin).  LSM-PE.2.2.2  Construct an analogical model (analogy) of the interaction of the internal components of a cell (e.g., working parts of a city, factory or automobile). Predict and justify, using the model, the impact on the cell or on the organism if one of the components fails to function properly.
