7.12 Organisms and environments. The student knows that living systems at all levels of organization demonstrate the complementary nature of structure and function

7.12 (C) recognize levels organization in plants and animals, including cells, tissues, organs, organ systems, and organisms

7.12 (D) differentiate between structure and function in plant and animal cell organelles, including cell membrane, cell wall, nucleus, cytoplasm, mitochondrion, chloroplast, and vacuole

7.12 (F) recognize the components of cell theory

7.12(C) recognize levels of organization in plants and animals, including cells, tissues, organs, organ systems, and organisms 

7.12(B)* identify the main functions of the systems of the human organism, including the circulatory, respiratory, skeletal, muscular, digestive, excretory, reproductive, integumentary, nervous, and endocrine systems 

7.12(E) compare the functions of cell organelles to the functions of an organ system 

7.13(A) investigate how organisms respond to external stimuli found in the environment such as fight or flight 

7.13(B) describe and relate responses in organisms that may result from internal stimuli such as fever or vomiting in animals that allow them to maintain balance 

7.7(B) demonstrate and illustrate forces that affect motion in organisms such as emergence of seedlings, turgor pressure, geotropism, and circulation of blood 

7.11(A)* examine organisms or their structures such as insects or leaves and use dichotomous keys for identification 

7.11(B) explain variation within a population or species by comparing external features, behaviors, or physiology of organisms that enhance their survival such as migration, hibernation, or storage of food in a bulb 

7.11(C)* identify some changes in genetic traits that have occurred over several generations through natural selection and selective breeding such as the Galapagos Medium Ground Finch (Geospiza fortis) or domestic animals and hybrid plants 

7.12(A) investigate and explain how internal structures of organisms have adaptations that allow specific functions such as gills in fish, hollow bones in birds, or xylem in plants 

7.12(C) recognize levels of organization in plants and animals, including cells, tissues, organs, organ systems, and organisms 

7.12(C) recognize levels of organization in plants and animals, including cells, tissues, organs, organ systems, and organisms 

7.5(A) recognize that radiant energy from the Sun is transformed into chemical energy through the process of photosynthesis 

7.5(B)* diagram the flow of energy through living systems, including food chains, food webs, and energy pyramids 

7.7(A) illustrate the transformation of energy within an organism such as the transfer from chemical energy to thermal energy 

7.10(A) observe and describe how different environments, including microhabitats in schoolyards and biomes, support different varieties of organisms 

7.10(B)* describe how biodiversity contributes to the sustainability of an ecosystem 

7.10(C)* observe, record, and describe the role of ecological succession such as in a microhabitat of a garden with weeds
