  1. Plant Kingdom

  2. Plant Kingdom • All plants are multicellular, with cell walls made of cellulose. • Autotrophs-make own carbs for energy through photosynthesis

  3. What Plants need to Survive • Sunlight • Water and Minerals • Gas Exchange • Movement of water and nutrition

  4. 4 Important Plant Groups are the: Mosses (Bryophytes) Ferns (Pteridophytes) Flowering Plants (Angiosperms) Conifers (Gymnosperms)

  5. Overview of Plant Kingdom

  6. Nonvascular Plants Mosses • The simplest of all land dwelling plants  • Nonvascular (no “veins”)-lack an internal means for • water transportation • Do not produce seeds or flowers • -Fertilization depends on water medium to get the sperm to the egg. • Lack a woody tissue necessary for support around • their “stems” and so are usually relatively short

  7. Moss Hornworts Liverworts • Spanish Moss

  8. Ferns Seedless, Vascular plants The ferns are an ancient lineage of plants, dating back to at least the Devonian. They include three living groups -- Marattiales, Ophioglossales, and leptosporangiate ferns -- as well as a couple of extinct groups.

  9. Vascular Plants Angiosperms and Gymnosperms • Internal transportation System • Xylem • Phloem • Enables plants to evolve into larger specimens. • Produce Seeds – protects and nourishes an Embryo of the new plant

  10. Main Structures of Seed Plants • Leaves - are the powerhouse of plants, and the major site of food production for the plant. Structures within a leaf convert the energy in sunlight into chemical energy that the plant can use as food.

  11. Leaf Structure

  12. Roots • Anchorthe plant in the soil. • Absorb water and mineral salts from the soil. • Store food. • Form a passage way for water and dissolved substances from the root into the stem and also for foods from the stem down into the root. Two kinds of Roots Tap roots - grows vertically down Fibrous roots – no root is larger than the rest

  13. Stems • They support the leaves and flowers • Transport water and food from place to place within the plant • Store food • Function in photosynthesis

  14. Dicot vs. Monocot • Two seed leaves (cotyledons) • Leaves are net veined • Vascular bundles in stems arranged in a circle • Flower parts in fours or fives or multiples • Seed chambers in fruit in fours or fives or multiples • Fibrous root system • One seed leaf (cotyledon) • Leaves have parallel veins • Vascular bundles in stems scattered • Flower parts in threes or multiples • Seed chambers in fruit in threes or multiples • Tap root system

  15. Dicot vs. Monocot

  16. Plant Tissue Systems • Dermal tissue- outer covering of plant • Vascular tissue- forms transport system in plants • Ground tissue- cells that lie between dermal and vascular tissue

  17. Vascular Tissue • Forms the transport system in plants • Xylem – water carrying tubes – one way transport • Phloem – sugar carrying tissues – two way transport

  18. Angiosperms - flowering plants

  19. Perfect Flower

  20. Gymnosperms • Conifers (pine cones) • Oldest vascular plants
