Kingdom Plantae

Plants get to do "it" twice

Chlorophyll - Green pigment for capturing light.

Cellulose - Polysaccaharide - makes up the cell walls of plants.

Nonvascular plants - Do not have tubes for moving food and water

Vascular plants - Have tubes for moving food and water

          Xylem - Tubes for moving water and minerals

          Phloem - Tubes for moving food (sugar)

Cuticle - Outer waxy covering on stems and leaves

Stomates - Little openings in the outer cover of the leaf which are not covered by the cuticle

*Bryophytes (Nonvascular Plants) - No vascular tissue so very short plants

          Mosses and Liverworts - reproduce by spores

          Sphagnum - A type of peat moss used in gardening.

*Ferns (Seedless Vascular Plants) - Have vascular tissue so tall plants that reproduce by spores.

          Rhizome - An underground stem.

          Fronds - The leaves of ferns

*Gymnosperms (Cone-bearing Plants) - Vascular plants. Spruce,firs and pine trees.

          Ginkgo Trees and Cycads - Have naked seeds.

*Angiosperms (Flowering Plants) - Vascular plants that have covered seeds.

          Flowers - For sexual reproduction.

                    Stamens - The male parts - produce pollen

                    Carpels - The female parts - produce eggs

                   Sepals - Leaf-like and often green, protect the bud.

                    Petals - Leaf-like and often brightly colored to attract pollinators.

Double fertilization - 2 sperm nuclei - One fertilizes the egg and forms the embryo. The other fuses with 2 haploid polar nuclei and forms the endosperm

          Embryo - 2N - First fertilization - Baby plant

          Endosperm - 3N - Second fertilization - Food for the embryo

Fruit - Ripened wall of the ovary that surrounds the seed or seeds.

          Seed - Has a seed coat, embryo, and endosperm.

Pollinators - carry pollen (sperm) to the carpel (eggs)

          Wind - Small green or white flower and odorless

          Insects - They see blue, yellow, and UV, but not red. They also have a strong scent.

          Birds - The flowers they pollinate tend to be red or yellow and have little or no scent.

          Bats - They are attracted to flowers that are open at night, are usually white, and have a strong scent.
