PPT-AP Biology Chapter 29 Seedless Plants: Bryophytes and Ferns

Objectives 1 Name the protist group from which plants are hypothesized to have descended and describe supporting evidence   2 Discuss some environmental challenges of living on land and describe how several adaptations meet these challenges. Chapter 21. Outline. Introduction. Phylum . Psilotophyta. – The Whisk Ferns. Phylum . Lycophyta. – The Ground Pines, Spike Mosses and . Quillworts. Phylum . Equisetophyta. – The Horsetails and Scouring Rushes. Lecture. r: Asst. Prof. Dr. İsmail EKER. GENERAL CHARACTERISTICS OF. . SEEDLESS . VASCULAR PLANTS. There are two types of leaves that may be found on seedless vascular plants. Microphylls. Small and have a single vascular strand. Mosses and Liverworts. Ferns and Horsetails. Mosses and Liverworts. Small. Live on bark, rocks, and soil. No vascular system. Must live in places that are wet. No true roots, stems, or leaves. Mosses. Chapter 7: Section 2. Seedless Plants. How do seedless plants reproduce?. Include all nonvascular plants and some vascular plants. Vascular vs. nonvascular. Nonvascular plants do not have structures that transport substances through the plant. Evolution of Land Plants. Land plants evolved from green algae. The green algae called charophyceans are the closest relatives of land plants. Comparisons of both nuclear and chloroplast genes. Point to charophyceans as the closest living relatives of land plants. Ferns, Club Mosses, Whisk Ferns, Horsetails. General Characteristics. Phylum: . Tracheophyta. “. true” land . plants.

A: Green algae are mostly aquatic. They are found in fresh and salt water, and in some moist areas on land. . archegonium. which includes bryophytes, . pteridophytes. and gymnosperms. The name of this group is derived from the name of female reproductive organ known as . archegonium. (singular) archegonia (plural). The archegoniate plants comprises the following groups .
