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 (broadleafed, 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.
