Vedclass · Answer

(A) The $Apical$ $Cell$ $Theory$ was proposed by $Carl$ $Wilhelm$ $von$ $Nageli$ in $1858$. This theory states that the entire plant body is derived from a single apical cell. It is applicable to lower plants like algae, bryophytes, and pteridophytes, but it does not explain the shoot apex organization in higher plants like gymnosperms and angiosperms, where a group of cells is responsible for growth. Therefore, the correct option is $A$.

According to the $Apical$ $Cell$ $Theory$, the shoot apex contains a single apical cell with three cutting faces. This theory applies to some higher algae, bryophytes, and pteridophytes, but not to gymnosperms and angiosperms. Who proposed this theory?
