Chapter 12Wildlife Plants

• Objectives
• Distinguish between domesticated and wild plants
• Describe types of plants based on life and
  vegetative growth
• Explain plant wildlife communities
• Describe plant life zones and why plants grow
  where they do
• Identify ways that plants help humans with foods,
  clothing, and shelter
• Explain how wildlife plants are destroyed

• Wildlife plants
• Wild flowers

4
Types of Plant Wildlife

• Life cycle
• Nature of the vegetative growth

5
Life Cycle

Plant Wildlife Communities

• Plant wildlife communities are plants that grow
  together in relative harmony
• The forest ground layer
• The shrub layer
• The understory layer
• The canopy

15
Layers in a Hardwood Forest
16
Plant Life Zone

• Plant life zones are used to study the kinds of
  plants that grow in a region due to elevation,
  latitude, and aspect
• Elevation is the distance a point on land is
  above or below sea level

17
The species of terrestrial plants found in a
biome depends on three major factors

• Precipitation
• Tropophyte
• Halophyte
• Phreatophyte
• Xerophyte
• Mesophyte
• Hygrophyte
• Temperature
• Soil type

18
Xerophyte (Cacti)
19
Mesophyte (Fir trees)
20
Hygrophyte
21
Feature of Hydrophytes

• Plants that grow in aquatic biomes are known as
  hydrophytes
• Stem air spaces help hold the plant upright and
  provide oxygen to the roots
• Seaweed is not plant, it is a collection of algae
  that grows to resemble plant structures

22
How Wildlife Plants Help Humans

• Food
• Medicine
• Raw materials
• Clean pollution from the environment
• Aesthetics
• Gene pool for domestic plants
• Animal wildlife habitat
• Regulate temperature

23
How wildlife plants are destroyed

• Habitat destruction
• Harvesting
• Chemicals and pesticides
• Damage and defacement
• Mineral extraction
• Over population of wildlife animals

24
Tests

• What is the distinction between domesticated and
  wild plants?
• What factors determine why wild plants grow where
  they do?
• Explain three ways wildlife plants help humans
• How are wildlife plants being destroyed?
