Kingdom Plantae

Characteristics of Plants: All plants are multicellular eukaryotes All plants are made of tissues and organs.

Characteristics of Plants: All plants have a cell wall. Contain chlorophyll for photosynthesis Autotrophs!

Living on Land Plants must find ways to get water, support their bodies and reproduce!

Plant Parts: Leaves Leaves: capture sun’s energy for photosynthesis Contain openings called stomata that can take in CO2 and stop water loss

Plant Parts: Stems Stems: carries substances from roots to leaves & provides support

Plant Parts: Roots Roots: anchor plant and absorb water and minerals

Transporting Materials Water taken in at roots Food made in leaves Vascular Tissue: tubes inside the plant that transport material up and down!

Vascular Tissues Xylem: tissue that carries water up to plant Phloem: tissue that carries food down to plant

Carnation Demo

Plant Response Tropism: a plant’s growth response towards or away from a stimulus EX: Phototropism: growth towards light

Classification of Plants: Nonvascular - no system of water transportation Vascular - contain vascular tissues that transfer water & food

Nonvascular Plants: Transport materials through absorption Low to the ground Must live close to water

Examples Mosses Hornworts Liverworts

Vascular Plants: Most plants are Vascular Has a water transport System! Have stems, roots, and leaves!

Seedless Plants Ferns, Horsetail, Club Moss All use spores to reproduce

Seed Plants Use seeds to reproduce Have stems, leaves, and roots Much more numerous!

Seed Dispersal Seeds protect the young plant Scattered by wind, water, or animals Germination: when the seed begins to grow

Gymnosperms VS. Angiosperms Produce “naked” seed No protective covering Needle-like leaves and deep root system Adapted to live in dry/cold places Produce flowers & fruits Seed protected by fruit or covering Live almost everywhere

Gymnosperms Cycads, Gingkos, Gnetophtyes, & Conifers Most reproduce using cones that contain pollen

Angiosperms Examples: Palm trees, fruit trees, flowering plants, etc. Reproduce using pollen

Monocots VS. Dicots Monocots Dicots “di ” means two two cotyledons “mono” means one one cotyledon (seed leaf) Leaves are long a thin in multiples of 3 “di ” means two two cotyledons Wide branching leaves in multiples of 4 or 5

Examples Monocots Dicots Corn Tulips Wheat Tomatoes Maple trees Sunflowers Roses
