Plants

• Plant anatomy

  The study of structure of organisms
• Morphology

  The study of form
• Plant physiology

  The study of function of cells tissue organs of living things
• Shoot system


  • Photosynthesis
  • Transport of food and water
  • Reproduction
  • Storage
• Root system

  • Absorbs water and nutrients
  • Transports it to the shoot system
• Shoot system

  • Photosynthesis
  • Transfer of food and water
  • Reproduction
  • Storage
• Root system

  • Absorbs water and nutrients
  • Transports it to the shoot system
• Importance of plant: photosynthesis sustain life on earth, fundamental source of food, medicine, fuel shelter and paper products and biotechnology
• Tissues

  • A group of cells
  • Two types: growing and permanent tissue
• Meristematic tissue

  Actively dividing cells
• Mitosis

  Cell division
• Merismatic tissue on the basis of origin

  • Apical meristem
  • Intercalary meristem
• Apical meristem

  Responsible for primary growth in plants
• Intercalary meristem

  For elongation of stems and leave and found at young leaves
• Permanent tissue

  Do not divide and they attain their mature form
• Dermal tissue or surface tissue


  External tissue which served as covering
• Epidermis


  Outermost layer of the primary plant body
• Periderm


  Forms during radical thickening and an armor that is protecting plant tissues
• Parenchyma cells


  Numerous type of cells in young plants
• Collenchyma cells


  Help young parts of plant shoot
• Sclerenchyma cells


  Support plants more than collenchyma cells
• Roots


  • Anchor the plant into the soil
  • Absorb water and nutrients
• Root types


  • Taproot
  • Fibrous root
• Taproot


  Main root and the zone of maturation, elongation, and cell division
• Zone of cell division


  Perpetually dividing
• Fibrous root


  Small root and prevent soil erosion
• Zone of elongation


  Increase in length
• Zone of maturation


  Where the roots begin to push out to the soil
• Stem


  Supports the plant and divided into segments called internodes
• 2 Leaf types

  • Simple leaves
  • Compound leaves
• Plant cell types (support and storage)

  Parenchyma cells

  Collenchyma cells

  Sclerenchyma cells
