LEARNING TARGET #1: DEFINE & UNDERSTAND the following vocabulary: - monomer - photosynthesis - polymer - stroma - autotroph - thylakoid - heterotroph - grana - ATP - photosystem LEARNING TARGET #2: EXPLAIN the connection between how an organism uses energy from the sun & whether - chloroplast - NADP + - glyceraldehyde 3-phosphate organism is an autotroph or heterotroph. LEARNING TARGET #3: Understand the purpose and importance of ATP. LEARNING TARGET #4: EXPLAIN the processes involved in photosynthesis (reactions, locations and equation). LEARNING TARGET #5: COMPARE and CONTRAST cellular respiration and photosynthesis. the NOTE: These are sample questions only & should be used to help master concepts. 1.
