Question

Considering mode of asexual reproduction, match the Column I with II and select the correct option.

Column I	Column II
a. Yeast	i. Fragmentation
b. Penicillium	ii. Zoospores
c. Filamentous algae	iii. Budding
d. Chlamydomonas	iv. Conidia

• A. $a-iii,b-iv,c-i,d-ii$
• B. $a-ii,b-iii,c-i,d-iv$
• C. $a-iv,b-iii,c-ii,d-i$
• D. $a-iii,b-ii,c-i,d-iv$

Answer 1

The correct option is A $a-iii,b-iv,c-i,d-ii$

• Yeast is a unicellular eukaryotic organism, falls in the category of class fungi. Yeast reproduces either sexually or asexually. The asexual mode of reproduction by fungi is called budding, in which a new organism evolve from offshoot or bud and derive the gene of that bud only, the offspring thus reproduced will be perfect copies of the parent.
  
• Penicillium is the filamentous fungi, here the members of this genus produce penicillin, which is used as antibiotics. The asexual reproduction of penicillium commence with the development asexual non-motile spores called conidia formed on conidiophore, it may be branched or unbranched.
  
• Spirogyra is a filamentous alga. It is commonly found in fresh water. Asexual reproduction of Spirogyra is by fragmentation, it undergoes intercalary mitosis to form new organisms, where fragments of filamentous algae break off and continue to grow.
  
• Chlamydomonas is a unicellular organism found in dormant water. The asexual reproduction of Chlamydomonas is by zoospores, which is flagellated asexual spores. Formation of zoospores is generally during the night and under favorable condition.
  

So, the correct answer is option A.
