Vedclass · Answer

(B) During microsporogenesis,the microspore mother cell $(MMC)$ undergoes meiosis to form a cluster of four haploid cells known as a microspore tetrad.These four microspores are initially held together by a special layer of carbohydrate called $Callose$.As the microspores mature and separate from each other,the enzyme $Callase$ is secreted by the tapetum,which degrades the $Callose$ wall,allowing the individual pollen grains to be released.

In angiosperms,the wall surrounding all four microspores of a microspore tetrad is made up of which substance?
