Article Evaluation
The article that I chose was too short hence the reason for the sentence below that was added. Also, after doing research it was found that Chromatin is synonymously used instead.

The word Karyotin is often times never used and Chromatin is used to replace the word; it is used as a synonym. Chromatin is made up of stands of DNA bound to a histone protein. The term chromatin means 'colored material' and refers to the fact that this material is easily stained for viewing with the microscope.

Callose
Callose is made by the Glucan Synthase-Like gene (GLS) in various places within a plant. Callose acts as a barrier to protect the plant from invading pathogens, repair the plant’s wounds, and controls the plant's permeability. Callose is very important for the permeability of plasmodesmata (Pd) in plants; the plant’s permeability is regulated by plasmodesmata callose (PDC). PDC is made by Callose Synthases and broken down by β-1,3-glucanases (BGs). The amount of callose that is build up at the plasmodesmatal neck, which is brought about by the interference of callose synthases (CalSs) and β-1,3-glucanases, determine the conductivity of the plasmodesmata.

When there is wounding in the plant tissue, this is fixed by the deposition of callose at the plasmodesmata and cell wall; this happens within minutes after damage. Even though Callose is not a constitutional component of the plant’s cell wall, it is related to the plant’s defense mechanism.
