Photosynthesis & Cellular respiration

Photosynthesis

The process by which plants make food using light energy, carbon dioxide, and water, producing glucose and oxygen.

Cellular Respiration

The process by which glucose and oxygen are broken down to produce carbon dioxide, water, and ATP.

Word Equation for Photosynthesis

Carbon dioxide + Water → Glucose + Oxygen.

Word Equation for Cellular Respiration

Glucose + Oxygen → Carbon dioxide + Water + ATP.

Chloroplasts

The organelles where photosynthesis occurs.

Mitochondria

The organelles where cellular respiration occurs.

Chlorophyll

The green pigment in plants that captures light energy for photosynthesis.

Autotroph

An organism that produces its own food (e.g., plants).

Heterotroph

An organism that consumes food for energy.

Glycolysis

The first step of cellular respiration occurring in the cytoplasm.

Granum

Stacks of thylakoids in chloroplasts, involved in light-dependent reactions.

Stomata

Openings in leaves that allow for gas exchange.

Krebs Cycle

The second stage of cellular respiration that occurs in the mitochondria.

Reactants of Photosynthesis

Carbon dioxide and water.

Products of Photosynthesis

Glucose and oxygen.

Reactants of Cellular Respiration

Glucose and oxygen.

Products of Cellular Respiration

Carbon dioxide, water, and ATP.

6 Carbons in Glucose

Glucose is a 6-carbon energy source for plants.

Photosynthesis at Night

Plants cannot photosynthesize without sunlight.

Macromolecules used for Respiration Fuel

Carbohydrates and lipids.

Carbon Dioxide

A gas released during respiration.

Role of Roots in Photosynthesis

Roots absorb water necessary for photosynthesis.

ATP

Energy currency produced during cellular respiration.
