7
Phylum Hepatophyta (liverworts)
E.x : Marchantia No true roots, No vascular tissues (no transport) Simple stems & leaves Have rhizoids (root like)
8
Asexual Reproduction Gametophyte has tiny cup shaped structures called gemmae cups

Phylum Polypodiophyta (ferns) A leaf (finely divided into small parts) root
15
Phylum Polypodiophyta (ferns)
ferns have vascular tissues Ferns are very leafy; leaves arise from an underground stem (rhizome) Each leaf consists of a stalk and a blade that is subdivided into pinnae (leaflets) Sori :clusters of sporangia
16
Fern Sorus and sporangium

29
angiosperms Known as flowering plants
Produce reproductive structures called flowers and fruits Produce seeds that are enclosed in ovaries (fruit) Includes phylum Magnoliophyta
31
Characteristics of Monocots
. one cotyledon leaves have parallel veins . e.g. zea maize
32
Characteristics of Dicot
. Seeds with two cotyledons . leaves have veins in network . e.g. Capsella
