Study Notes
Medicinal Properties of Plants
- Plants produce biologically active chemicals that benefit themselves and other organisms.
Reasons for Medicinal Properties
- Plants produce herbicides to inhibit growth of competing plants, enhancing their own survival.
- Plants produce substances to deter insects and herbivores from browsing, promoting self-preservation.
Chemical Compounds in Plants
- Plants produce a wide variety of chemical compounds to maintain vigor, promote growth, and resist environmental challenges.
Photosynthesis in Plants
- Photosynthesis occurs in green plant organs containing mesophyll cells and chlorophyll pigment.
- Plants absorb water (H2O) from soil and carbon dioxide (CO2) from the air during photosynthesis.
- Electron molecules from sunlight are used in the photosynthetic process.
