Determining evolutionary relationships

Which type of plant is most closely related to flowering plants?

CONIFERS

history of classification systems

Aristotle – Plants and Animals

  • Linneaus – developed BINOMIAL NOMENCLATURE
    • TWO KINGDOMS: plants and animals
    • THREE kingdoms: plant, animal, Protist
    • FIVE kingdoms: plant, animal, Protist, fungi, Moneran
History of classification systems
classification
CLASSIFICATION

Scientific name is genus and species name. Organisms in same genus are closely related

dichotomous key
Dichotomous key
  • Always begin with #1
  • Follow directions using choices given
  • What shape is “Gina”?
  • Equilateral triangle
plant adaptations
PLANT ADAPTATIONS

Root, stem, Leaf

Flowers and Fruits

Flowers have bright petals to attract pollinators

Pollen (Sperm) can be transferred by animals

When egg joins with pollen, a seed is formed in the ovary

The ovary becomes the fruit

Fruit surrounds and protects seed

Fruit also helps get baby plants in seeds away from parent plant

  • Roots are adapted to absorb water with root hairs
  • Leaves are adapted for photosynthesis by being flat and green
  • Stems move water with xylem
