1 | Phycomycetes | p | Penicillium |
2 | Ascomycetes. | q | Alternaria |
3 | Basidiomycetes | r | Albugo |
4 | Deuteromycetes | s | Puccinia |
Albugo is a classic example of Phycomycetes (obligate parasite causing plant diseases).
Penicillium represents Ascomycetes (economically important for antibiotics).
Puccinia is a Basidiomycete (causes wheat rust).
Alternaria is a Deuteromycete (causes early blight in potatoes/tomatoes).
Fungal Class | Characteristics | Correct Example | Incorrect Options |
---|---|---|---|
1. Phycomycetes | Aquatic/filamentous fungi | (r) Albugo (white rust) | (p) Penicillium is Ascomycete |
2. Ascomycetes | Sac fungi (ascus-bearing) | (p) Penicillium (antibiotic producer) | (s) Puccinia is Basidiomycete |
3. Basidiomycetes | Club fungi (basidium-bearing) | (s) Puccinia (rust fungus) | (q) Alternaria is Deuteromycete |
4. Deuteromycetes | "Imperfect fungi" (no known sexual stage) | (q) Alternaria (plant pathogen) | (r) Albugo is Phycomycete |
Correct Option: D (1)-(r), (2)-(p), (3)-(s), (4)-(q)
Phycomycetes are represented by Albugo, which is a genus of parasitic fungi (r).
Ascomycetes are represented by Penicillium (p), which is a type of fungus that produces conidia (asexual spores).
Basidiomycetes are represented by Puccinia (s), a type of rust fungus.
Deuteromycetes are represented by Alternaria (q), which is a genus of fungi that causes plant diseases.
Thus the Correct Option: D (1)-(r), (2)-(p), (3)-(s), (4)-(q).
A convex lens has power \( P \). It is cut into two halves along its principal axis. Further, one piece (out of two halves) is cut into two halves perpendicular to the principal axis as shown in the figure. Choose the incorrect option for the reported lens pieces.
The equation \[ 2 \cos^{-1} x = \sin^{-1} \left( 2 \sqrt{1 - x^2} \right) \] is valid for all values of \(x\) satisfying:
A metallic sphere of radius \( R \) carrying a charge \( q \) is kept at a certain distance from another metallic sphere of radius \( R_4 \) carrying a charge \( Q \). What is the electric flux at any point inside the metallic sphere of radius \( R \) due to the sphere of radius \( R_4 \)?
The circuit shown in the figure contains two ideal diodes \( D_1 \) and \( D_2 \). If a cell of emf 3V and negligible internal resistance is connected as shown, then the current through \( 70 \, \Omega \) resistance (in amperes) is:
