Comparing Photosynthesis and Cellular Respiration worksheet | Live ... - Free Printable

Of course! Let's solve this worksheet step by step. The image compares Photosynthesis and Cellular Respiration, showing how they are interconnected processes in living cells.

🔍 Step 1: Identify the Organelles

- The green, disc-shaped organelle with stacks of thylakoids is the Chloroplast — where photosynthesis occurs.
- The red, bean-shaped organelle with folded inner membranes (cristae) is the Mitochondrion — where cellular respiration occurs.

🔄 Step 2: Understand the Flow of Materials

Photosynthesis (in chloroplasts):
- Inputs: Sunlight, Water, Carbon dioxide
- Outputs: Glucose, Oxygen
- Equation:
`Sunlight + Water + Carbon dioxide → Glucose + Oxygen`

Cellular Respiration (in mitochondria):
- Inputs: Glucose, Oxygen
- Outputs: Carbon dioxide, Water, ATP (energy)
- Equation:
`Glucose + Oxygen → Carbon dioxide + Water + ATP`

Notice how the outputs of one process are the inputs of the other — they form a cycle!

✔ Step 3: Fill in the Diagram Labels

We’ll label the boxes based on the arrows and their direction:

#### Top Left (Sun symbol box):
➡️ This is the input for photosynthesis → Sunlight

#### Below Sunlight (two orange input arrows to chloroplast):
➡️ Inputs for photosynthesis → Water and Carbon dioxide

#### Above Chloroplast (label for the organelle):
➡️ Chloroplasts

#### Top Right (green output arrow from chloroplast):
➡️ Outputs of photosynthesis → Glucose and Oxygen

#### Bottom Right (sun symbol near mitochondrion):
➡️ This represents energy release → ATP (though sometimes shown as heat/energy, ATP is the main usable product)

#### Below Mitochondrion (two green input arrows):
➡️ Inputs for cellular respiration → Glucose and Oxygen

#### Bottom Left (orange output arrows from mitochondrion):
➡️ Outputs of cellular respiration → Carbon dioxide and Water

#### Label for mitochondrion:
➡️ Mitochondria

#### Process labels:
- Green arrows around chloroplast → Photosynthesis
- Orange arrows around mitochondrion → Cellular respiration

✍️ Step 4: Fill in the Sentences at the Bottom

> The outputs/products of photosynthesis are the _inputs_ of _cellular respiration_.

> The outputs/products of cellular respiration are the _inputs_ of _photosynthesis_.

> The purpose of photosynthesis is _to convert sunlight into chemical energy (glucose) and produce oxygen_.
*(or more simply: “to make food (glucose) for the plant using sunlight”)*

> The purpose of cellular respiration is _to break down glucose and release energy (ATP) for the cell’s activities_.

> Photosynthesis is done by _chloroplasts_.

> Cellular respiration is done by _mitochondria_.

#### Sentence Completion:

1. The outputs/products of photosynthesis are the inputs of cellular respiration.
2. The outputs/products of cellular respiration are the inputs of photosynthesis.
3. The purpose of photosynthesis is to convert light energy into chemical energy stored in glucose, releasing oxygen as a byproduct.
4. The purpose of cellular respiration is to break down glucose and release usable energy (ATP) for cellular functions.
5. Photosynthesis is done by chloroplasts.
6. Cellular respiration is done by mitochondria.
