Plant anatomy

• non seed bearing plants

  Non flowering plants and produce spores instead of seeds
• Vescular plants 


  Possess xylem and phloem
• Non - vascular plants

  Low growing , reproduce with spores and need a moist habitat
• Gymnosperm 


  Has seeds but does not bear flowers

  its seeds are naked and do not bear seed coats
• Angiosperms 


  Has seeds and bears flower

  has coated seeds and undergoes double fertilization

  monocot and dicot
• No. Of Cotyledon for monocot

  1
• No. Of Cotyledon for Dicot

  2
• Root system for Monocot

  Fibrous roots
• Root system for Monocot

  Tap roots
• No. Petals Monocot 


  multiples of 3
• No. Petals dicot 


  Multiples of 4 & 5
• Xylem 


  Moves water
• phloem 


  Moves sugar
• Leaves monocot 


  Smooth, parallel venation
• Leaves Dicot 


  Textured, branching venation
• vascular tissues monocot 


  Scattered
• Vascular tissues Dicot 


  Arranged in a ring
• Central Vacuole 


  Maintains osmotic pressure against cell wall
• Cell wall 


  Shapes supports and protects the cell
• Plastid 


  Houses pigments that gives colors
• Chloroplast 


  Contains chlorophyll
• Chromoplast 


  Makes and stores plant pigments
• Parenchyma cells 


  thin,primary walls that retain their protoplasm at maturity
• Function of parenchyma cells

  photosynthesis And respiration

  storage
• Collenchyma cells 


  thick, primary walls that retain their protoplasm at maturity
• Roles of Collenchyma cells

  Flexible support system
• Sclerenchyma cells 


  Cells with lignified secondary walls that have lost protoplasm
• Functions of sclerenchyma cells

  Protection, structural support and water conduction
• types of tissue 


  Dermal , ground , Vascular
• Components of Dermal tissue

  Epidermis

  periderm
• Components of Ground tissue

  Parenchyma cells

  collenchyma cells

  sclerenchyma cells
• Function of dermal tissue 


  Protection, prevent water loss
• Function of ground tissues

  Metabolism , storage , support
• Function of Vascular tissue

  Transport water and sugar
• description of dermal tissue

  Outer covering of the leaves , stems and roots
• trichome 


  Hair like projection that typically serves as protection
• Cuticle 


  Thin layer over the external part of the dermal tissue to prevent water loss ; absent in roots
• Stomata 


  Control water lost of transpiration ; allow gas exchange
• Guard cells 


  Regulate the opening and closing of stomata and prevents water loss
• Bundles
