Q. In Chlamydomonas, zoospores are

1. Laterally flagellated
2. Pyramid shaped
3. Exogenously originated
4. Non- motile asexual spores

1. they have no cell wall
2. they have no mycelium
3. sexual reproduction is absent
4. asexual reproduction is absent

Q. Find the pair which incorrectly matched for the disease and its causal organism.

1. Late blight of potato - Alternaria solani
2. Black rust of wheat - Puccinia graminis
3. Loose smut of wheat - Ustilago nuda
4. Root-knot of vegetables - Meloidogyne sp.

Q.

What is the causative agent of the black stem rust?

Q. In fungi, sporangiospores and ascospores are found in bag-like structures but are always present in even numbers. These spore types are not same because

1. They are basically the same, but the sporangiospores are always larger.
2. Ascospores are formed as a result of meiosis, while sporangiospores are a result of mitosis.
3. Sporangiospores are produced by sexual recombination, while ascospores are produced asexually.
4. The structure are the same, but they were named differently before they were determined to have the same function.
5. They are basically the same, but ascospores are always larger.

Q. Which one of the following matches is correct ?

1. Agaricus - parasitic fungus - Basidiomycetes
   
2. Phytophthora - Aseptatemycelium - Basidiomycetes
3. Alternaria - Sexual reproduction absent - Deuteromycetes
4. Mucor - Reproduction by Conjugation - Ascomycetes
