There are two types of leaves that may be found on seedless vascular plants. Microphylls. Small and have a single vascular strand. 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. Fruit Functions. F. ruit . = mature. , ripened . ovary. P. revent . the seeds from drying .

Plantae. (page 550). Characteristics:. - eukaryotic. . - . multicellular. (most). . - have cell walls made of a complex carbohydrate called cellulose . . - sessile (anchored by roots). Materials extracted from plants are used in about 50% of the medicines used in the western world.. Products from plants are often cheaper and safer than man made (synthetic) ones.. To identify which plants are useful, scientists study traditional folklore and observe their practices. Many of the chemicals withdrawn from plants have been used by natives for many years.. 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.. Plants= eukaryotic, . multicellular, . photosynthetic. . Green Algae. Bryophytes. (Non-vascular). Tracheophytes. (Vascular). Non-seeds. Seeds. Gymnosperms. (Naked seeds). Angiosperms. (Seeds in flowers and fruit). Nonvascular plants. have no vessels, no roots, no stems or leaves. Examples: Mosses & Liverworts. Vascular Tissue. Xylem: transports water. Phloem: transports food & nutrients. Gymnosperms. "naked seeds". Plants…. Eukaryotic (have a nucleus). Have cell walls made of cellulose. Carry out photosynthesis using the pigment chlorophyll a and chlorophyll b. Belong to the kingdom Plantae. Types of plants. 1) Green Algae. Plants= eukaryotic, . multicellular, . photosynthetic. . Origin of Land Plants?. Evidence that Green Algae are the ancestors. 1) DNA. 2) Ch a & b. 3) True starch inside chloroplasts. 4) Diverse life cycles & reproduction.
