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.

Answer:
The answer to the question: Class II MHC proteins are found on which of the following cell types, would be: on macrophages and lymphocytes, particularly T-Cells.
Explanation:
MHC, or Major histocompatibility complex, is a very important part of the immune response that the body gives against an invading pathogen, or other foreign substances. There are three types in the human body, Class I, Class II and Class III and each of them will play a role on the cellular membrance of different types of cells and mediate different types of responses. In the human body, this histocompatibility complex is best known as HLA, or human leukocyte antigen, and it will ensure the recognition, or non-recognition of substances, tissues, and other organisms, by the human immune system. Class II, as mentioned before, are most usually found on the immune cells macrophages and lymphocytes, and they are the ones responsible for presenting antigens to these proteinic antibodies so that the immune cells can initiate a proper immune response.
