The answer for your question is D
Genetic relationships, gene expression patterns, microRNAs, and active hormonal controls all contribute to the genetic foundation of leaf form. organelle 1 is large vacuole, 2nd organelle is mitochondria, organelle 3 is nucleus and organelle 4 is cell wall.
The size of the cell and the number of cells determine the size of the leaf. Plant hormones, growth-regulating factors (GRFs), TEOSINTE BRANCHED1/CYCLOIDEA/PCF (TCP), WUSCHEL RELATED HOMEOBOX (WOX), and other regulatory factors control cell expansion and differentiation [3,4].
Rough E.R. makes and transports substances through the cell and Smooth E.R. does not have ribosomes; Ribosome make protein for the cell.

Allopatric speciation, also referred to as geographic speciation, is a method of the formation of new species due to isolation of the species from one another through geographic means.
The first step in this process is geographic isolation, which means that the original population is divided into two groups due to geographical reasons such as movement of continents or formation of water bodies.
Next, the species are subjected to different selection pressures due to their different environments. Eventually, the gene pool becomes very different for the two species due to the different selection pressures and because they are not allowed to mix.
Finally, after enough time passes, speciation occurs, which means that the two populations cannot breed to form fertile offspring.
