Members of this group are photosynthetic organisms which live primarily in freshwater, though some are found in marine waters, in damp soil, or on tree trunks. Symbiotic algae: Symbiotic (mutual) association with fungi in lichen, in Bryophytes (Anthoceros), in Pteridophytes (Azolla), gymnosperms (corolloid roots of Cycas) and in angiosperms. Contents i. ii. Ø  The growth and development consists of a number of distinct morphological and cytological stages, Ø  The sequence of these orderly changes is called life cycle, Ø  Life cycle: sequence of all different phases or events through which an organism passes from zygote (diploid) of one generation to the zygote of the next generation through gametes (haploid), Ø  There are five types of life cycles in algae based on the number of haploid and diploid generation, (1).

Parenchymatous forms (Sargassum, Laminaria), Ø  Algae also shows great diversity in pigmentation, Ø  Different groups of algae have different pigment composition, Ø  Distribution pattern of pigments has great taxonomic significance in algae, Ø  The classification of algae by Fritsch is primarily based of the pigmentation in algae. As the algae grow, they consume nutrients such as inorganic nitrate, inorganic phosphate, nitrite, ammonia, and ammonium from the water. They are the primary energetic source for many stream food webs, fixing carbon from the atmosphere through photosynthesis , which is then transmitted through the web via consumer pathways. This book covers topics such as: evolution of sex and sexuality in algae; and, pigments in algae with their chemistry and the evolution of thallus in algae. Similar to pigmentation in algae, the distributional difference in reserved food is also in the classification of different algal groups. The Chlorophyceae are a large and important group of freshwater green algae. ⊕. Zoospore, aplanospore, hypnospore, tetraspore, autospore, akinetes etc are the important spore types in algae. Also called Rhodophyta, it is a distinctive species found in marine as well as freshwater ecosystems.

Ø  Pigments in algae belongs to three major categories: Ø  All major algal groups have at least one characteristic pigment, Cyanophyceae (blue green algae): Phycocyanin, Chlorophyceae (green algae): Chlorophyll b, Chlorophyll a is universally present in all algal grous, Ø  Except in Cyanophyceae (blue green algae, BGA) pigments in algae are found in membrane bound organelles called plastids, Ø  In BGA, plastids are absent, pigments located at peripheral cytoplasm called chromoplasm.
