What goes on inside a cell?
Types of cells
Size and scale
Cells are packed
Here is a (false color) example of proteins in a cell’s cytoplasm – notice how densely packed this is.
6.MS-LS1-1. Provide evidence that all organisms (unicellular and multicellular) are made of cells.
6.MS-LS1-2. Develop and use a model to describe how parts of cells contribute to the cellular functions of obtaining food, water, and other nutrients from its environment, disposing of wastes, and providing energy for cellular processes.
Disciplinary Core Idea Progression Matrix: LS1.A Structure and function
Grades 6-8: All living things are made up of cells. An organism can be made of one cell
(unicellular) or many cells (multicellular). Within cells, specialized structures are responsible for specific functions. In multicellular organisms, cells work together to form tissues and organs that are specialized for particular body functions.
Grades 9-10: Systems of specialized cells within organisms carry out essential functions of life. Any one system in an organism is made up of numerous parts. Feedback mechanisms maintain an organism’s internal conditions within certain limits and mediate behaviors.
