TYPES OF PLANTS
Bryophytes
Gymnosperms
Angiosperms
•Non-vascular
•No xylem or phloem
•Examples are mosses
•They are small
•Have to be near water
•No pollen, seeds, flowers, or fruits
•Vascular
•Xylem to move water
•Phloem to move food
•Examples are conifers
•Have pollen (sperm)
•Have seeds on cones
•No fruits or flowers
•Vascular
•Xylem to move water
•Phloem to move food
•Examples are flowering plants like
oak trees, corn, and roses
•Have pollen (sperm)
•Have seeds in fruits
•Have flowers
PLANT ADAPTATIONS
ROOT, STEM, LEAF
Roots are adapted to absorb
water with root hairs
Leaves are adapted for
photosynthesis by being flat and
green
Stems 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
TYPES OF ANIMALS
Annelids
Insects
Amphibians
