NOMENCLATUREo TWO KINGDOMS: plants and
animalso THREE kingdoms: plant,
animal, Protisto FIVE kingdoms: plant, animal,
Protist, fungi, Moneran
CLASSIFICATION
Scientific name is genus and species name. Organisms in same genus are closely related
DICHOTOMOUS KEY
• Always begin with #1• Follow directions using choices given• What shape is “Gina”?• Equilateral triangle
PLANT ADAPTATIONS
ROOT, STEM, LEAFRoots are adapted to absorb water with root hairsLeaves are adapted for photosynthesis by being flat and greenStems move water with xylem
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
