Plant Kingdom
What is a Plant?
• A plant is a multicellular autotroph.
• Plant cells are eukaryotic.
• Plant cells have a cell wall and
chloroplasts.
• Plants make their
own food in the process
of photosynthesis.
Classifying Plants
• Non vascular
– low growing because they have no
support or way to transport materials
• Vascular
– can grow tall because they have
Vascular tissue which
• Transports water and food throughout a
plant’s body
• Gives strength and stability
Adaptations for living on land
• Plants get water and nutrients from the soil
• Plants lose water through transpiration
• Plants have a cuticle to keep them from
drying out.
• Some plants use a system of tubelike
structures called Vascular Tissue to move
materials.
• Vascular tissue also supports some plants
Reproduction
• Sexual Reproduction
– Seed plants use seeds and pollen
– Seedless plants use spores
• Asexual Reproduction
– Runners
– Tubers
Gymnosperms
• A seed plant that produces naked seeds
because the seeds are NOT enclosed in a
fruit
• Reproduce with pollen and seeds
• Have needle-like or scale-like leaves
• Deep-growing root systems
Angiosperm
• Flowering
plants
• They produce
flowers and
seeds
enclosed by a
protective fruit
