Vascular vs. Non-Vascular
Non-Vascular• Water habitats (needed for
reproduction)• No internal transport
systems• Live close to ground• Examples: mosses,
liverworts, hornworts
Vascular• Terrestrial plants (most don’t
depend on H20 for PS)• Able to transport nutrients via
transport system• Vascular system provides support
enabling them to grow larger• Examples: ferns, herbs, shrubs,
trees, flowering plants
Vascular are divided into two groups…
Seedless Plants
• Reproduce by spores• Need water for reproduction• E.g. Ferns
Seed Plants• Reproduce by seeds• Adaptation for terrestrial life• E.g. Flowering plants, trees,
crops
• “naked”• Cones are reproductive
structure• Male cone = pollen• Female cone = ovule• Thin needle-like leaves
covered with a waxy cuticle (adaptation for hot/dry summer and cold winters)
• E.g. Pine, spruce, junipers, fir
Gymnosperms
Seed plants are divided into two groups…
• “vessel”• >250, 000 different kinds• Success of angiosperms due
to insect/flower relationship
• Seed is contained within a “vessel” called a fruit
• E.g. crops, deciduous trees, flowering plants
Angiosperms
Seed plants are divided into two groups…
• Research the difference between these two groups. Include:– Examples– Number of cotyledons– Number of seed leaves– Arrangement of vascular bundles– Type of veination on leaves– Arrangement of floral parts
