Study Notes

Photosynthesis

Purpose is to produce glucose (food) for plant cells.
Reactants required: light energy, carbon dioxide (CO2), and water (H2O).
Products generated: glucose (C6H12O6) and oxygen (O2).
Occurs in the chloroplasts of plant cells.
Environmental conditions needed include sunlight and daylight.
Only producers (like plants) perform photosynthesis.
Evidence of occurrence includes chlorophyll presence, reflecting green light.

Cellular Respiration

Purpose is to release usable energy for cellular activities.
Reactants needed: glucose (C6H12O6) and oxygen (O2).
Products formed: usable chemical energy, carbon dioxide (CO2), and water (H2O).
Takes place in the mitochondria.
No specific environmental conditions required; can occur in light or darkness.
All organisms, including producers and consumers, undergo cellular respiration.
Evidence includes yeast inflating a balloon with carbon dioxide and increased carbon dioxide production during exercise.

Interaction Between Photosynthesis and Cellular Respiration

Photosynthesis provides reactants for cellular respiration; glucose and oxygen.
Cellular respiration produces CO2 and H2O, which are reactants for photosynthesis.
This interdependence is crucial for the survival of living organisms.

Plants and Energy Storage

Plants can obtain glucose through starches when unable to perform photosynthesis.
Starches are long chains of glucose stored in structures like cotyledons of seeds.
Starch reserves support young plants or those lacking sunlight.

MicroGreens Observations

Green color in MicroGreens indicates active photosynthesis (chlorophyll absorbing light energy).
Growth of MicroGreens demonstrates cellular respiration, as energy from glucose is essential for cell division and growth.
