Q.1. Describe in brief occurrence, structure and reproduction of Algae.

Ans. Occurrence: Algae, an important group of Thallophyta, are

cosmopolitan in a distribution and universal in occurrence. Algae are found on the trunk of trees, on telephone wires, on rocks in hot springs and in several other unusual habitats. Algae thrive well in snow and geysers. The most favourable habitat of algae is salt water.

Structure: In the organization of the plant, algae exhibit a greal

diversity. The size of the algae is very much variable. A huge size laminariales occurs from a microscopic unicellular Chlamydomonas. Chlamydomonas is the most primitive algae. Volvox is microscopic and multicellular. which is found in colonial forms. Cladophora is branched, while Ulothrix and spirogyra are unbranched among the filamentous forms.

Reproduction:

Stem (i) Vegetative reproduction: This is the process of propagation in which

portions of the plant body are separated to give rise to new individuals without any change in the protoplast.

(ii) Asexual reproduction: This reproduction takes place by the

following methods:

(a) By Zoospores: These are the common occurrence in algae, and are

formed in the favourable conditions. They are practically similar to parent cell and are liberated by breaking up of the mother cell wall. Zoospores are formed from certain older cell of filaments. To form Zoospores. the older cytoplasm is divided to form zoospores which escapes from the mother cell wall. Zoospores are always motile.

(b) By Akinetes: In this case, the protoplast of a single cell converts in a single akinete. Sometimes they are formed in chaims. Lach akinete may develop into a new plant. e.g. oedogonium, ulothrix, and members of my sophyceae.

(с) Ву Пурnospores: When the aplanospores undergo a long resting period and become thick walled, they are said to be hypnospores e.g. Pediastrum & sphaerella.

(d) Palmella Stage: Sometimes the zoospores do not come out of the

mother cell but they remain surrounded by a mucilaginous sheath inside the mother cell. On division, they form colony-shaped structure called the Palmella. On liberation, they form new plants e.g. chlamydomonas

(e) By Endospores: They are formed within the cells in many blue- green algae and bacillariophyceae.. Each endospore develops in a new individual on the approach of favourable conditions.

(f) By Aplanospores: Aplanospores are the eliminated bodies of motile phase of Zoospores. They develop in unfavourable conditions.

14. Draw a neat labelled diagram of a typical bacterial cell to show the detailed structure and describe the function of important organelles.

Or, Describe ultrastructure of bacterial cell.

15. Discuss the structure of bacterial cell wall. Mention the cell wall composition of gram-positive and gram-negative bacteria.

16. Describe the various methods of reproduction in Bacteria.

Or, Describe the methods of multiplication in bacteria.

17. Describe the economical importance of bacteria.

Or, Give an account of industrial application of bacteria (Micro- organism).

18. Describe the role of microbes (bacteria) in Agriculture.

19. Discuss the role of microbes in nitrogen fixation.

20. Define antibiotics. Discuss the molecular basis of how penicillin inhibits growth of bacteria.

21. Discuss the economic importance of bacteria in food and medicine.

22. Discuss the importance of bacteria in dairy industry

Q.2. Describe the thallus organisation in Algae showing evolutionar tendency.

Or, Describe organisation and evolution of thallus in chlorophyceae.

Or, Give an account of the range of thallus structure in Algae wit suitable examples.

Ans. The members of Chlorophyceae show a great variation in the rang of vegetative structure from primitive microscopic unicellular form to macroscopie multicellular forms. The following are the various type of plan bodies met within this class :

1. Motile forms: These forms of algae are the simplest in the organization of thallus. The simplest type of chlorophyceae are unicellular and remain motile practically throughout their lifetime. Chlamydomonas affords ar example of the simplest form seen in the green algae. They have a spherical unicellular, uninucleate and biflagellate structure with a prominen cup-shaped chloroplast. The cells swim with their flagellat…

Q.6. Discuss the role of algae in human welfare.deft

Or, Discuss the economic importance of algae.

Ans. Role and Importance of Algae:

(i) As a food for man: Since the pre-historic times, several sea weeds have

been used as direct source of food for human beings. Several freshwater algae have also been utilised in the preparation of various kinds of vitaminized food. As we know well that the fundamental food of sea living stock are algae and
