CLASSIFICATION OF PLANTS INTO GROUPSPlants can be classified into several groups. Plants canbe grouped according to the structure of their roots, stem, leaves, flower & seeds. Plants are classified in two major groups : non-vascular & vascular plants.
DESCRIPTION OF NON-VASCULAR & VASCULAR PLANTS •Lacks vascular tissues. NON- •Does not have vascular bundles for VASCULARPLANTS transporting food &water. •They are called bryophytes. •Have vascular tissues. •Does have vascular bundles for VASCULAR PLANTS conducting food &water. •They are called tracheophytes.
Non-vascular plants have 3 kinds. They are mosses, liverworts,& hornworts.mosses liverworts hornworts
DESCRIPTION OF MOSSES, LIVERWORTS & HORNWORTS Mosses are Liverworts are so Hornworts have a bryophytes that called because their simple &grow alone on the thallus looks like the undifferentiated ground. They are liver’s lobes. Unlike thallus & a complexerect w/ short leafy mosses, liverworts spore-bearing stems & are lie horizontally on structure. anchored to the the ground.ground by rhizoids.
Vascular plants have 2 kinds. They arespore-bearing & seed-bearing plants. spore-bearing plants seed-bearing plants
DESCRIPTION OF SEED-BEARING & SPORE-BEARING • It constitutes the other group of Seed-bearing tracheophytes. About 95% of tracheophytes are seed-bearing. plants • Their reproductive structures Spore-bearing are called spores located in specialized structures called plants sporangia.
Seed-bearing plants are divided into two distinct groups of tracheophytes, the gymnosperms & the angiosperms. SEED- BEARING GYNOSPERMS ANGIOSPERMS
DESCRIPTION OF GYMNOSPERMS • They produce naked seeds. • Their seeds are not enclosed in a ovary. • Their seeds are enclosed in woody structures called cones or strobili. • They are called conifers because theyGYMNOSPERMS produce cones. • In most gymnosperm, there is a dominant main stem w/ conspicuously smaller branches. • Their leaves are covered with thick layer of cuticle.
EXAMPLES OF GYMNOSPERMS PINE TREE SPRUCES HEMLOCK FIRS
DESCRIPTION OF ANGIOSPERMS • Angiosperm are the flowering plants. • They produce seeds that are enclosed in a ovary. • Fruit trees, bushes & vegetables belong toANGIOSPERMS this group.
EXAMPLES OF ANGIOSPERMS FRUIT TREES BUSHES VEGETABLES
Angiosperms are divided into two subclasses – the dicotyledons & monocotyledons. ANGIOSPERM DICOT MONOCOT

THE OTHER WAY OF GROUPING SEEDPLANTS IS ACCORDING TO THE LENGTH OF THEIR GROWING SEASONS PLANTS ANNUALS BIENNIALS PERENNIALS
DESCRIPTION OF ANNUALSANNUALS These are plants that grow and produce flowers, fruits and seeds in one season and then die. Most vegetable crops are annuals
DESCRIPTION OF BIENNIALSBIENNIALS These are plants that take two years to complete their cycle. The plants grow and develop in a year’s time. For its 2nd year, they produce flowers, fruits and seeds and afterwards die.
DESCRIPTION OF PERENNIALS PERENNIALS These plants lived for more than 2 years. Their life cycle – growth of flower, fruit and seed bearing activities continuously goes on. Most of trees and many grasses belong to this group.
