4. Aspergillus, Bread mould, Paramecium.

Answer 1

Correct Answer - Option 2 : Aspergillus, Penicillium, Bread mould

Aspergillus, Penicillium and Bread mould are fungi.

Concept:

• Fungi constitute a unique kingdom of heterotrophic organisms.
• Fungi show a great diversity in morphology and habitat.
• Fungi are cosmopolitan and occur in air, water, soil, animals, and plants.
• The study of fungi is Mycology.
• Fungi are categorized into 4  classes: Ascomycetes, basidiomycetes, Phycomycetes & Deuteromycetes

Explanation:

• Aspergillus:
  • It is a Fungus genus that belongs to the class Ascomycetes or the sac fungi.
  • It includes several species like A. Proliferans, A. Fumigatus, A.Flavus & A. Niger
• Rhizopus (the bread mould): 
  • It is a Fungus genus that belongs to the class Phycomycetes.
  • Members of Phycomycetes are found in aquatic habitats and on decaying wood in moist and damp places or as obligate parasites on plants.
• Penicillium:
  • It is a Fungus genus that belongs to the class Ascomycetes or the sac fungi.
  • Its mycelium is branched and septate.
  • It has asexual spores are conidia produced exogenously on the special mycelium called conidiophores. Conidia on germination produce mycelium.

 

• ​Lactobacillus: 
  • Lactobacillus is a gram-negative bacteria.
  • It promotes the formation of curd. It multiplies in milk and converts it into curd.
• Paramecium:
  • The paramecium is a ciliated protozoan.
  • It comprises a single cell only.
• Spirogyra:
  • Spirogyra is a free-floating green alga. It belongs to the Chlorophyta kingdom.
  • Spirogyras are filamentous algae that consist of thin unbranched chains of cylindrical cells
• Amoeba:
  • The amoeba is amoeboid protozoan.
  • It has false feet called pseudopodia that are used for locomotion & capturing of prey.
