Cell Energy & Body SystemsANSWER KEY
Name: Period: Date:
1.Cells are filled with cytoplasm and organelles, each with specific functions
2.Gene expression controlled by chemical signals determines cell type
3.Genes are discrete units; dominant/recessive patterns determine expression
4.Mutations can be beneficial, harmful, or neutral depending on context
[!] STUDY GUIDE: Big Ideas Use to answer form questions!
1.Photosynthesis captures energy. Plants use chloroplasts to convert sunlight + CO2 + water into glucose (food) and oxygen.
2.Cellular respiration releases energy. Mitochondria break down glucose + oxygen to make ATP (usable energy) + CO2 + water.
3.Body systems work together. Digestive, circulatory, and respiratory systems deliver nutrients and oxygen so cells can make ATP.
Sunlight -> Photosynthesis (Chloroplast) -> Glucose -> Cellular Respiration (Mitochondria) -> ATP (Energy)
ENERGY FLOW: From Sunlight to Usable Cell Energy (ATP)

[?] THE PHENOMENON Write BEFORE Hook form
What happens when cells stop working together properly?
Your body burns about 2,000 calories a day. That energy powers 37 trillion cells working together. What happens if one system fails? Why do you feel tired when you skip meals or can't breathe well?

How do chloroplasts (W1) and mitochondria (W1) work together in the energy cycle?
Why does a muscle cell (W2) need more mitochondria than a fat cell?
[/] DAY 2 EXIT TICKET Final check before Science Circle +5 pts
Q1 (NEW):
Compare photosynthesis and cellular respiration. How are they opposite processes?
Q2 (SPIRAL-W1/W2):
Why do plant cells have both chloroplasts AND mitochondria, while animal cells only have mitochondria?
Q3 (INTEGRATION):
Explain why someone with lung disease (respiratory system) would feel tired even if they eat enough food (digestive system works fine).
