OH.2. Life Sciences: Students demonstrate an understanding of how living systems function and how they interact with the physical environment. This includes an understanding of the cycling of matter and flow of energy in living systems. An understanding of the characteristics, structure and function of cells, organisms and living systems will be developed. Students will also develop a deeper understanding of the principles of heredity, biological evolution, and the diversity and interdependence of life. Students demonstrate an understanding of different historical perspectives, scientific approaches and emerging scientific issues associated with the life sciences.
2.2. Grade Level Indicator: Characteristics and Structure of Life: Explain that multicellular organisms have a variety of specialized cells, tissues, organs and organ systems that perform specialized functions.
2.3. Grade Level Indicator: Characteristics and Structure of Life: Identify how plant cells differ from animal cells (e.g., cell wall and chloroplasts).
2.A. Explain that the basic functions of organisms are carried out in cells and groups of specialized cells form tissues and organs; the combination of these cells make up multicellular organisms that have a variety of body plans and internal structures.
2.C. Explain how energy entering the ecosystems as sunlight supports the life of organisms through photosynthesis and the transfer of energy through the interactions of organisms and the environment.
