ADVERTISEMENTS: Important modes of reproduction found in the class polysiphonia are as follows: The reproduction takes place by means of vegetative, sexual and asexual methods. There are three types of plants, i.e., male, female and tetrasporophyte. The male plants bear antheridia and the female the procarps. ADVERTISEMENTS: The asexual plant or tetrasporophyte produces tetraspores. All […]

Method of locomotion: Notes: cilia (hair-like projections) used for locomotion. Using your dissecting and compound light microscope, observe Polysiphonia.

Some common Indian species are P. ferulacea, P. urceolata and P. variegata. Ø Polysiphonia reproduces by means of vegetative, asexual and sexual methods. Ø Vegetative reproduction is by fragmentation of the thallus. Ø Sexual reproduction is oogamous type. Ø Asexual reproduction is by the production of Tetraspores. Sexual reproduction in Polysiphonia: Ø The life cycle of Polysiphonia is completed in three phases. TYPE II Polysiphonia - occurrence , structure, reproduction & development is discussed with detail.

Chloroplasts evolved following an endosymbiotic event between an ancestral, photosynthetic cyanobacterium and an early eukaryotic phagotroph. This event (termed primary endosymbiosis) resulted in the origin of the red and green algae, and the glaucophytes, which make up the oldest evolutionary lineages of photosynthetic eukaryotes. Fungi are multicellular,with a cell wall, organelles including a nucleus, but no chloroplasts. They have no mechanisms for locomotion. Fungi range in size from microscopic to very large ( such as mushrooms). Nutrients are acquired by absorption.
