Kingdom Plantae and the evolution of terrestrial plants

1
Kingdom Plantaeand the evolution of terrestrial
plants
2
Characteristics

• Organisms that lack mobility
• Eukaryotic cells that have numerous organelles
• Ability to make sugars (carbohydrates) through
  photosynthesis
• How many plants can you think of in the next five
  minutes? GO!

3
Vocab

• Non-vascular without conductive tissues
  bryophytes
• Vascular has conductive tissues tracheophytes
• Xylem and phloem - conductive tissues which
  transport water and nutrients throughout the
  plant
• Which of our plants are tracheophytes?
• What are some physical characteristics of
  bryophytes and where are they likely found?

Conductive tissues
5
Vocab

• Cuticle a layer of noncellular material
  secreted to the outside of the plant
• Stomata pores on the leaves of a plant which
  control gas exchange

6
Terrestrial life out of the water

• Plants had to adapt to conditions of life on land
• - stems and roots for support
• - roots to anchor to the ground
• - vascular system to transport water and
  nutrients
• - waxy cuticle to prevent plants from losing
  too much water
• - stomata to regulate gas exchange and reduce
  water loss
• - spores, pollen, nectar, flowers, fruit and
  seeds help terrestrial plants reproduce

7
Vocab

• Spermatophytes a division of vascular plants
  which have seeds the most recently evolved plant
  group
• Gymnosperms Have naked seed, usually inside
  cones
• Angiosperms Produce seeds enclosed in fruit
  formed by certain flower parts
• Which of our plants fall into these categories?
