Germination
Mosses are

Mosses and Ferns are both
Primitive Plants
Conifers are
trees that bears cones and evergreen needle like or scale like leaves
Gymnosperm Seeds are
ex: Conifers
a plant that has seeds unprotected by an ovary or fruit
Angiosperms are
Seeds that are covered unlike Gymnosperms
Monocots (monocotyledon) is a one of the 2 sub-classes of Angiosperm.
They have
One cotyledon only
Parallel leaf veins
Fibrous Roots
C4 Metabolism (for dry places)
Eudicots is a one of the 2 sub-classes of Angiosperm.
They have
2 cotyledons Branched Leaf veins Taproot 4 or 5 flower petals C3 Metabolism
The three basic Plant organs
Roots , Stems , and Leaves
Root System Carry’s
water and minerals to the Shoot system (plants parts above ground)
Shoot System Delivers
Sugar to the roots.
Roots are multi cellular organs with important functions.
_______
________

Adventitious roots
Seedless vascular plants and monitors have a
