Do Now: Elodea = Living (L); Granite = Non-Living (NL); Fallen Log = Once-Living (OL); Yeast = Living (L). Mystery Question: All living things are composed of one or more cells.
Cell Theory Notes: Pillar 1: one; Pillar 2: unit; Pillar 3: pre-existing (or existing).
Hierarchy Table: Tissue = similar cells; Organ = different tissues; Organ System = body function (or job).
Activity A (Ranking): 1 = Epithelial Cell; 2 = Stomach Lining Tissue; 3 = Stomach; 4 = Digestive System; 5 = Human Being. Plant Check: Leaf = Organ.
Activity B (Systems Scenario): Model Answer: Damaging lung tissue prevents oxygen from diffusing into the blood. This impairs the lung (organ) function, which prevents the respiratory and circulatory systems from delivering oxygen to the rest of the body (organism).
Exit Ticket: Q1: A. Q2: Model Response: Cells group together to form tissues. Different tissues assemble to create organs, which work in coordinated organ systems that keep the entire organism alive.

Glucose (Sugar) + Oxygen (\(O_2\))
🍃 Chlorophyll: Green pigment that traps sunlight.
🍬 Glucose: Chemical energy stored for growth.
Plants store glucose, but how do plants and animals turn that sugar into usable energy?
Energy Release Sugar to ATP
Location: Mitochondria
Inputs (Reactants)
Glucose (Sugar) + Oxygen (\(O_2\))
→ Inside Mitochondria
Outputs (Products)
ATP Energy + Carbon Dioxide (\(CO_2\)) + Water (\(H_2O\))
⚡ ATP: The cellular energy “battery” used for movement, thinking, cell division, and growth!
CRITICAL: BOTH plants and animals perform cellular respiration!
The Big Picture Cycling of Matter & Energy
🍃
Takes in \(CO_2\) + \(H_2O\) → Produces Glucose + Oxygen
Supplies fuel and air for consumers!
⚡
Takes in Glucose + Oxygen → Produces \(CO_2\) + \(H_2O\) + ATP
Supplies \(CO_2\) and water back to producers!
The outputs of one process are the exact inputs for the other!
Plants and animals depend on this cycle to keep Earth's living systems in balance.
Common Pitfall Inspire Science Alert
“Plants do photosynthesis, and animals do respiration.”
THE TRUTH:
Plants do BOTH! Plants make glucose in chloroplasts, but they have mitochondria to break down that glucose into ATP energy day and night.

1. Why do plant cells contain mitochondria if they already have chloroplasts?
A) Mitochondria are required to capture sunlight when chloroplasts run out of chlorophyll.
B) Chloroplasts make glucose, but mitochondria must break that glucose down into usable ATP.
C) Mitochondria produce water and carbon dioxide so the plant never needs rain or air.
D) Plant mitochondria only activate after the plant dies to decompose dead plant tissues.
2. Trace how energy from the Sun ends up powering a student's muscle cells to run:

Do Now: Plant uses chlorophyll in leaves to trap solar energy and assemble glucose from water and carbon dioxide.
Guided Notes: Photosynthesis Inputs = Carbon Dioxide; Outputs = Sugar. Respiration Inputs = Oxygen; Outputs = ATP.
Activity A: 1 = P; 2 = R; 3 = BOTH; 4 = R.
Activity B (Biosphere): Model Answer: The plant uses light and carbon dioxide from the snail to perform photosynthesis, releasing oxygen and glucose. The snail consumes oxygen and plant matter to perform cellular respiration, releasing carbon dioxide and water back to the plant.
Exit Ticket: Q1: B. Q2: Model Response: Radiant energy from the Sun is captured by plant chloroplasts to produce glucose. When a student eats plant-based food, their digestive and circulatory systems transport glucose to muscle cells. Mitochondria in muscle cells perform cellular respiration, breaking down glucose and oxygen into ATP energy that powers muscle contractions.
