PPT-Seedless vascular plants

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. 1 | Page CRYPTOGAMS - Flowerless or seedless plants - Lower and more primitive plants - 3 main groups i.e. Thallop hyte, Bryophyte and Pteridophyte - Thallophytes include: Algae, fungi, Bacteria and - ka,’ ‘Ruby Seedless,’ ‘Flame Seedless,’ and ‘Perlette.’ ‘Thompson Seedless’ is also dominant in most com - mercial raisin-producing countries worldwide. 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. The earliest plants were similar to today’s mosses. They grew close to damp ground and depended on water to complete their life cycles (to carry the gametes).. Kingdom . Plantae. (page 550). Characteristics:. VASCULAR . Plants. Ch. 29.3 – Dec 5, 2014.

Kingdom Plantae. Land plants – some terrestrial, some aquatic.. High diversity with distinguishing characteristics.. Kingdom Plantae . 4 main groups:. Bryophta. (mosses, liverworts, hornworts). Xylem vs. Phloem. Seeds vs. Spores. Root Types. largest group . well-developed system for transporting water and food; they have true roots, stems, and leaves.. help circulate water and food throughout the plant.. Scientists sort plants into different groups, just like they do animals.. Nonvascular plants do not have true roots, stems, or leaves because they don’t have veins.. Because they absorb water and food from their surroundings, they cannot grow very tall.. Roots. , Stems, and Leaves. Reproduction . in Flowering . Plants. Plant . Characteristics. Plants come in all sizes, from the tiny duckweed which grows to only about 10 mm in length, to the giant redwood which grows to about 100 m in height.. Why should we care about plants, at all?.

Evidence that Green Algae are the ancestors. 1) DNA. 2) Ch a & b. 3) True starch inside chloroplasts. 4) Diverse life cycles & reproduction. Bacteria. Archaea. Lobose amoebae. Cellular slime molds.
