  2. BWhat does the filiform apparatus do at the entrance into ovule?
  3. CWhat does the filiform apparatus do at the entrance into ovule?
  4. DWhat does the filiform apparatus do at the entrance into ovule?

Correct answer

B. What does the filiform apparatus do at the entrance into ovule?

Step-by-step solution

The m−m -cresol is the m-methyl phenol. Phenol is acidic in nature. It gives the acid-base reaction with base. So, when it reacts with the base, it will form the phenolate ion. After that phenolate ion act as a nucleophile. This nucleophile gives the nucleophilic substitution reaction with the alkyl halide. It will follow the SN2{S}_{N}2 reaction mechanism.
