All Kinds of Plants nonseed plants – do not reproduce with seeds seed plants – reproduce with seeds - plants have flowers or cones
Mosses Mosses – small nonseed plants that lack true roots, stems, and leaves reproduce by spores spores – one-celled structures that grow into new plants grow only in moist places
Spores are the little dots on the underside of the leaf Spores are the little dots on the underside of the leaf. Plants such as mosses and ferns reproduce by spores instead of seeds.
Liverworts nonseed plant lack true roots, stems, and leaves grow in moist places (ex: streams)
Ferns before dinosaurs lived – giant ferns spore-forming have roots, stems, and leaves grow in moist places similar to mosses but with special tubes that carry water from the roots to other parts of the plant fronds – leaves of a fern plant
Horsetails look like paintbrush live in marshes & swamps reproduce by spores underground stems
Conifers cover much of northern part of world today cone-bearing plants have roots, stems, and leaves reproduce by seeds keep leaves in fall needle-like leaves - ex: pines, spruce, firs, cedar
spruce tree pine tree cedar tree fir tree
Flowering Plants have roots, stems, leaves reproduce by seeds fruit develops to cover and protect seeds monocot – seeds in one piece (ex: corn) dicot – seeds have two sections (ex: lima bean)
monocot – leaf has parallel veins - corn dicot – leaf has netted (branched) veins - lima bean
