- Yeast is a simple unicellular fungus that grows in saccharine fluids and produces proteins, B vitamins, and enzymes. It is used as a nutritional supplement and in manufacturing. - Seaweed contains algin and fucosterol. It is used to prepare alginates and can help reduce obesity. - Carrageenan from seaweed is used as a demulcent, emulsifier, and in peptic ulcer treatment. - Lichen contains lichenin, isolichenin, and fumaroproto-cetrartic acid. It is used as a bitter tonic and to prepare a demulcent and nutrient jelly.

Thallophytes
• Simplest form of plants. • Plants which are not differentiated into roots, stems and leaves. • They include: bacteria, algae, fungi and lichens.
• Botanical origin: • Yeast consists of unicellular fungus of Saccharomyces cerevisae Meyen emend. Hansen, S. carlsbergenis Hansen and S.monacensis Hansen Family: Saccharomycetaceae
• Preparation: • Yeast are grown in saccharine fluids containing suitable proportions of nitrogenous matter and inorganic salts. • Dried yeast: obtained by drying bakers yeast at a temperature not exceeding 30°C. • It consists of dead cells and cells in the resting stage.
• Constituents: • contains: 73% moisture, 13% protein and 0.27% oil. • Zymase enzyme convert monosaccharides into alcohol and carbon dioxide. • Source of vitamin B complex: - aneurin HCl (vit.B1) - Riboflavin (vit.B2).
Actions and Uses - a good source of vitamin B complex. - a source of protein (1gm yeast = 450 mg protein). - Dried yeast used in making tablets of yeast and used in manufacture of nucleic acid. - In treatment of boils and in combination with salicylic acid in acne and dermatitis.
Botanical Origin: • The dried thallus of , and , Family: Fucaceae. G.Origin: • Shores of the Atlantic Ocean.
• Color: olive-brown. • 30-100 cm in length. • Branching: Dichotomous. • Tips are ovoid have the reproductive structures known as the conceptacles.
• Mucilagenous substance “Algin” or “Fucin”. • Iodides, bromides and Sterols “Fucosterol”. 1- Reduce obesity. 2- Preparation of alginates.
• Botanical Origin: The dried bleached thallus of , Family: Gigartinaceae. • G.Origin: Northwestern coast of France, Bristih Islands.
• Color: - green to dark purple when fresh - liale yellow bleached and dried. • Branching: Dichotomous, carries ovoid brown cystocarps.
• Mucilagenous substance “Carageenin”. • Iodides and Bromides. 1- Nutritive Demulcent in peptic ulcers. 2- Emulsifying agent.
• Botanical Origin: The dried foliaceous lichen of , Family: Parmeliaceae. • G.Origin: England, Sweden and Central Europe.
1- Two complex carbohydrates: “lichenin” and “Isolichenin”. 2- Bitter crysatlline fumaroproto-cetrartic acid. 1- Bitter stomachic and tonic. 2- to prepare a demulcent and nutrient jelly.
