Types of Plants and Trees

Plants and Trees

• Types of Plants:
  • Flowering plants (angiosperms): produce flowers and seeds
  • Coniferous plants (gymnosperms): produce cones and seeds
  • Ferns (pteridophytes): non-flowering, spore-producing plants
• Importance of Plants:
  • Produce oxygen through photosynthesis
  • Provide food and shelter for animals
  • Help regulate the climate and weather patterns
• Tree Characteristics:
  • Trunk: main stem of the tree
  • Bark: protective layer on the outside of the trunk
  • Leaves: carry out photosynthesis
  • Roots: absorb water and nutrients from the soil

Insects and Bugs

• Insect Characteristics:
  • Exoskeleton: outer covering that provides protection and support
  • Segmented body: divided into head, thorax, and abdomen
  • Six legs: jointed legs for movement and sensory organs
  • Compound eyes: made up of many small lenses for vision
• Types of Insects:
  • Beetles (coleoptera): most diverse group of insects
  • Flies (diptera): have a single pair of wings
  • Bees and wasps (hymenoptera): have four wings and are social insects
• Bug vs. Insect:
  • "Bug" often refers to any small, crawling creature
  • Insects belong to the class Insecta, a specific taxonomic group
  • Not all bugs are insects, but all insects are bugs

Plants and Trees

• Flowering plants produce flowers and seeds, while coniferous plants produce cones and seeds
• Ferns are non-flowering, spore-producing plants
• Plants produce oxygen through photosynthesis, providing food and shelter for animals and regulating the climate and weather patterns
• The trunk is the main stem of a tree, protected by the bark, and supported by roots that absorb water and nutrients from the soil
• Leaves carry out photosynthesis, the process by which plants produce energy from sunlight

Insects

• Insects have an exoskeleton, a segmented body divided into head, thorax, and abdomen, and six jointed legs
• Insects have compound eyes made up of many small lenses for vision
• Beetles are the most diverse group of insects, while flies have a single pair of wings and bees and wasps are social insects with four wings
• The term "bug" refers to any small, crawling creature, but insects belong to the specific taxonomic group Insecta
• Not all bugs are insects, but all insects are bugs
