plants are important to people because they
provide oxygen to animals.

are a source of food.

provide fiber which is used for fabric.

provide shelter, roofing, and building materials.

produce by-products such as dyes, decorative bark.

may be used to alter the local environment.

produce medicinal chemicals.

Plants are important to people because they:
ways in which plants alter their environments
Shade.

Windbreaks.

Erosion control.

Noise control.

Reduction of glare.

Beautification.

Production of nitrogen in legumes.

Act as settling chambers for pollutants.

Ways in which Plants Alter their Environments
shade
Shade
  • Reduces loss of soil moisture by cooling the soil.
  • Reduces local air temperature.
windbreaks
Windbreaks
  • Reduce soil moisture loss by reducing evapo-transpiration.
  • Warm areas in cool weather by reducing the wind chill factor.
  • Prevent soil erosion.
erosion control
Erosion Control
  • Roots capture soil particles as they wash across the surface of the ground.
  • Leaves capture and slow rain water so soil particles are not so easily dislodged.
noise control
Noise Control
  • Plants block sound waves from noisy streets, railroads, or buildings.
reduction of glare
Reduction of Glare
  • Plants absorb and soften sunlight.
  • Plants shade areas to reduce glare from sidewalks, streets, and buildings.
beautification
Beautification
  • Plants help to make areas more attractive.
production of nitrogen in the soil
Production of Nitrogen in the Soil
  • Soil micro-organisms coexist with legumes to make nitrogen for the host plant, as well as other nearby plants.
plants act as settling chambers
Plants Act as Settling Chambers
  • Plants absorb particulate pollution (pollution which is in particles) and hold them within themselves .
