Presentation transcript:

Pterophytes (Ferns and Relatives) What types of plants are seedless and vascular? How do Ferns reproduce?

Types of Seedless Vascular Plants Club Mosses Ancient species grew to be over 10 stories tall Lycopodium looks like mini pine tree

Types of Seedless Vascular Plants Whisk Ferns – grow in tropics and subtropics Horsetails Grow in wetlands Have leaves that grow in whorls around stem

Types of Seedless Vascular Plants Ferns Have underground stems (rhizomes) Leaves are called fronds

Fern Reproduction

Fern Reproduction Sporophyte Stage (Fern Plant) Produces a sorus made of sporangia that contain haploid spores Gametophyte Stage (Prothallus) Contain antheridium and archegonium
