Presentation Transcript
plant survival on land
Plant Survival on Land
  • Three adaptations have allowed plants to thrive on land
    • The ability to prevent water loss
    • The ability to reproduce without water
    • The ability to absorb and transport nutrients
preventing water loss
Preventing Water Loss
  • Cuticle – a waxy protective covering on plant surfaces that prevents water loss
reproducing by spores and seeds
Reproducing by Spores and Seeds
  • Spore – a haploid reproductive cell surrounded by a hard outer wall
  • Seed – an embryo surrounded by a protective coat
absorbing and transporting materials
Absorbing and Transporting Materials
  • Vascular tissue – transports water and dissolved substances from one part of the plant to another
  • Two types of specialized tissue
    • Xylem – carries water from the roots to the stems and leaves
    • Phloem – carries organic compounds (like carbohydrates) in any direction
classifying plants
Classifying Plants
  • Nonvascular plants – don’t have true vascular tissue or roots, stems, or leaves
    • Example – mosses
  • Vascular plants – have vascular tissue and true roots, stems, and leaves.
    • Example – ferns, conifers, flowering plants
vascular plants
Vascular Plants
  • Seedless
    • Ferns
  • Seed plants – produce seeds for reproduction
    • Gymnosperms – conifers (cone bearing trees)
      • Example – Pine trees
    • Angiosperms – flowering and fruiting plants
      • Example – apple and orange trees
types of trees
Types of Trees
  • Deciduous trees – leafy trees. Lose their leaves.
  • Coniferous trees – have pine needles rather than leaves. Have cones.
monocots and dicots
Monocots and Dicots
  • Flowering plants (angiosperms) are divided into:
    • Monocots
    • Dicots
plant cells
Plant Cells
  • Three types of plant cells:
    • Parenchyma
    • Collenchyma
    • Sclerenchyma
self quiz
Self Quiz
  • What are vascular plants? What are nonvascular plants?
  • What are angiosperms? What are gymnosperms?
  • What are monocots? What are dicots?
  • What are seeds? Cones? Fruit?
leaf functions
Leaf Functions
  • Leaves serve as the primary site of photosynthesis in most plants
plant leaves
Plant Leaves
  • Stoma (stomata)– the major pathways through which CO2 enters and O2 leaves a plant
  • Guard cells – control the opening and closing of the stoma
types of leaves
Types of Leaves
  • Simple leaf
  • Compound leaf
  • Doubly compound leaf
