The Plant Kingdom

• Cell Number: Multicellular with specialized tissues

• Cell Type: Eukaryotic Plant Cells (Chloroplast and Cell Wall made of Cellulose Carbohydrates)

• Feeding: Photosynthetic autotrophs

• Reproduction: Sexual with seeds

Plant Classification

• Plants evolved from green algae

• They are first classified as vascular and non-vascular

Non-Vascular

• plants that do not have veins to carry water and food through the plant

• Have spores instead of seeds• Examples:

– mosses

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 veins to carry water and food through the plant

• Examples:– roses

Vascular

• American dogwood tree

Vascular

• Roses

Vascular

• Grass

Plant Classification

• Vascular plants are further classified based on specific characteristics.

• Trees can be classified as – gymnosperm conifers (cone-bearing

evergreens) Ex: pine trees– deciduous angiosperms (broad-

leafed, flowering trees that lose their leaves in the fall.) Ex: apple trees

Plant Classification

• Flowering plants are categorized into two major groups– Monocots: Parallel veins and petals

in multiples of 3 (draw one)• Ex- Tulip

– Dicots: Branching veins and petals in multiples of 4 or 5 (draw one)

• Ex- Rose

Photosynthesis

• Plant cells produce their own food through a process called photosynthesis.

• Photosynthesis allows plants to convert light energy into food energy. (write the equation)

Parts of a Flower

Male Parts

Female Parts

Each flower has both male and female parts. Male parts produce pollen while female parts produce ovules. Pollen + Ovule = Seed. Fruits sometimes grow from the swollen ovary as a means to transport seeds.

Parts of a Flower

Male Parts

Female Parts

Flowers form mutualistic symbiotic relationships with pollinators like insects and birds. Plants attract them with petals and create a nectar the pollinators eat. In return the pollinators carry pollen to other plants.
