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. EXPLORING CITRUS CULTIVARS 191were incubated at 27 Ferns, Club Mosses, Whisk Ferns, Horsetails. General Characteristics.

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 Many of the chemicals withdrawn from plants have been used by natives for many years..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.. 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". Lesson 3: Plant Reproduction. Essential Questions. What is the alternation of generations in plants?. How do seedless plants reproduce?. How do seed plants reproduce?. How can you identify fruits?. ACTIVITY. 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. FLORIDA PLANTS What is a native plant?
