The correct Answer is:
To determine how many statements are correct, let's analyze each statement one by one: 1. **Statement (a)**: "Deuteromycetes are also known as imperfect fungi because only vegetative or asexual phases of these fungi are known." - **Analysis**: This statement is correct. Deuteromycetes, or imperfect fungi, are classified as such because they do not have a known sexual reproductive stage. They reproduce asexually, which is why they are termed "imperfect." 2. **Statement (b)**: "A large number of members of deuteromycetes are decomposers of litter." - **Analysis**: This statement is also correct. Many deuteromycetes function as saprophytes, meaning they decompose dead organic matter, contributing to nutrient cycling in ecosystems. 3. **Statement (c)**: "In club fungi, the stage between dikaryotization and karyogamy is usually prolonged." - **Analysis**: This statement is correct as well. In club fungi (Basidiomycetes), the dikaryotic stage (where two nuclei coexist in a cell) can be prolonged before the nuclei fuse during karyogamy, which is a characteristic feature of their life cycle. 4. **Statement (d)**: "Some members of phycomycetes are obligate parasites on plants." - **Analysis**: This statement is correct. Some members of Phycomycetes (now often classified under Zygomycetes) are indeed obligate parasites, meaning they depend on their host plants for survival. Now, let's summarize the correctness of each statement: - Statement (a): Correct - Statement (b): Correct - Statement (c): Correct - Statement (d): Correct **Conclusion**: All four statements are correct. **Final Answer**: 4 statements are correct. ---

Assertion : It is poosbile that the asexual and vegetative stage of a fungi have been given one name ( and placed under deuteromycetes) and the sexual stage another ( and placed under another class). Reason : Once sexual stages of members of deuteromycetes were discovered they were often moved to phycomycetes and ascomycetes.

Which of the following statements are correct regarding Deuteromycetes? I. Deuteromycetes are called perfect fungi. II. Members of Deutermycetes mycetes were often moved to ascomycetes or basidiomycetes once their sexual stages were studied. III. Large number of (No Suggestions) are decomposers that help in nutrient cycling. IV. Their mycelium is aseptate and unbranched.

How many statements are correct? (a) Hind II always cut DNA molecules at particular point by recognizing a specific sequence of 6 bases. (b)After the restriction endonuclease action, single stranded portions which are overhanging stretches called sticky ends because they form nucleotide bonds with their complementary cut counter part. (c)The separated bands of DNA are cut out from the agarosegel and extracted from gel piece. This step is known as spooling. (d)Taq polymerase is used between annealing and extension of r-DNA technology.

Make corrections wherever you find mistake in spellings/words in the following paragraph/sentences. (A) Protozoans are generally multinucleate, but all ciliates and many amoeboid types are uninucleate. (B) Contractile vacuoles are found in almost all terrestrial protozoans for maitenance of carbon concentration of cell body, the phenomenon is known as osmoregulation. Contractile vacuole also helps in reproduction. (C) The protozoan cell body is either naked or surrounded by a rigid pellicle. Cellulose is present in pellicle. Some protozoans secrete shells of various organic compounds as external covers. (D) Ascomycetes are coenocytic as well as multicellular fungi. In the later, mycelium is asceptate. The asexual spores are formed in chains are called zoospores. The spores are formed endogenously, i.e., inside sporangium. (E) Sexual reproduction in Rhizopus is oogamous and the mode of sexual fusion is gametangial contact type. (F) A lichen is structurally organised entity consisting of the permanent association of a fungus and an alga. The fungal component of a lichen is called phycobiont and the algal component is called mycobiont. Both mycobiont and phycobiont are associated in parasitic union in which the fungus is more predominant and alga is subordinate partner.
