The Plant Kingdom

Plant Classification Domain: Eukaryota Kingdom: Plantae Cell type: eukaryotic Cell number: multicellular Feeding: autotrophic (photosynthesis) Reproduction: Seeds/spores

The Plant Kingdom This kingdom has organisms that are multi-cellular, have cell walls and chlorophyll, produce their own food, and don’t physically move from one place to another.

Plant Classification Plants evolved from green algae (protists) They are first classified as Nonvascular – short plants with no transport tissue (like veins), e.g. moss Vascular – taller plants with veins, e.g. trees Xylem – veins for water Phloem – veins for food

Non-Vascular plants that do not have tubes to carry water up the plant or tubes to carry food made in the leaves down the plant Examples: mosses liverworts ferns hornworts

Non-Vascular Spore: the reproductive cell of a nonvascular plant SPORES!

Non-Vascular Moss

Non-Vascular Liverwort

Non-Vascular Fern

Non-Vascular Hornwort

Vascular Plants that have tubes to carry water up and food down the plant Examples: American dogwood tree roses grass

Vascular American dogwood tree

Vascular Roses

Vascular Grass

Plant Classification Vascular Plants can further be classified as Gymnosperms – cone bearing plants, e.g. pine trees Angiosperms – flowering plants, e.g. roses

Plant Classification Angiosperms are classified as Flowering plants Covered seed FRUIT or FLOWERS Regardless of type, flowers are great for reproduction. Flowers attract animals that can help pollinate the plant.

Plant Classification Gymnosperms are classified as Cone bearing Open seed PINECONES

Photosynthesis Plant cells produce their own food through a process called photosynthesis. Photosynthesis allows plants to convert light energy into food energy.
