THE PLANT KINGDOM Woodstown High School Biology

CARL LINNAEUS  BOTANIST (person who studies plants)  Designed the system used for CLASSIFYING plants  Known as the “Father of Ecology”

SYSTEM of CLASSIFICATION 1. DOMAIN 2. KINGDOM 3. PHYLUM 4. CLASS 5. ORDER 6. FAMILY 7. GENUS 8. SPECIES

DOMAINS  All living things are GROUPED into THREE domains.  BACTERIA  ARCHAEA  EUKARYA (having EUKARYOTIC cells…plants & animals)

PLANT KINGDOM VASCULAR  Plants that have tube- like cells used to transport food and water throughout the plant  XYLEM ---carries water from roots to stem and leaves  PHLOEM ---carries food (sugar)from leaves to roots NON-VASCULAR  Plants that DO NOT have tube-like cells to transport food and water throughout the plant.  Plants that DO NOT have leaves, stems or roots. They get water through a root- like structure called RHIZOIDS  Plants that grow in damp, shady areas on sides of trees and rocks (MOSS)

FERNS  Ferns are a seedless VASCULAR plant.  Over 12,000 known species of ferns.  Leaves of a fern are called FRONDS  SORI are the cluster of reproductive spores on the under side of the frond

CONIFERS  Conifers are GYMNOSPERMS, they have SEEDS but NO flowers.  Leaves (needle-like) remain GREEN all year  Reproductive organs are found in CONES (pollen & eggs).  Cones produce SEEDS  Conifer trees grow large & tall…used for LUMBER & PAPER

CONES

FLOWERING TREES & PLANTS  Trees & plants that come from SEEDS and have FLOWERs are known as ANGIOSPERM  They have vascular cells for transporting food & water.  Over 250,000 known species  The FLOWER contains the reproductive organs that produce SEEDS.
