Plasmids are found within the nucleus of a cell, it is a small, circular piece of DNA found in bacteria and yeasts, which is able to replicate independently of the chromosomes. They are predominantly found in prokaryotes (in the cytosol of prokaryotes and some eukaryotes.

*Though plasmids are found in eukaryotes such as yeast, they are very rare in eukaryotes in general. Plasmids are much more prevalent in prokaryotes such as bacteria. Bacterial plasmids may be linear or circular and are basically pieces of DNA that carry non-essential genes and replicate independently of the bacterial chromosome. Since bacteria don't have nuclei, bacterial plasmids exist freely in the cytosol in a supercoiled manner. Examples of bacterial chromosomes include the F plasmid, which is essential to bacterial conjugation (horizontal gene transfer) and various resistance plasmids that confer resistance to toxins including antibiotics.
Plasmodesmata are not easily visible in Elodea because the plant cells are tightly packed and have high chloroplast content, which can obstruct the view. In persimmon, the plasmodesmata may be more prominent due to differences in cell arrangement and structure. Special staining techniques or higher magnification may be needed to see plasmodesmata in Elodea.
There is no exact equivalent, but a gap junction is the closest thing an animal cell has to plasmodesmata.
Plasmodesmata is an organelle that can only be found in Plant cells. It basically connects all the cells together. There is more madness to the logic like why it is connected, and what is transported in the Plasmodesmata. But for now that is all you need to know.
facilitate communication and transport of materials between plant cells, allowing for the passage of water, nutrients, and signaling molecules. Plasmodesmata play a crucial role in coordinating growth and development, as well as in the defense responses of plants.

a plasmodesmata is usually brown and button shaped

Plasmodesmata are holes in the cell wall of plants and algae that allow the cellular transfer of of proteins and macromolecules in and out of the cell. The cell wall does not have gap junctions or intermembrane proteins like the cell membrane does, so the cell needed another way to allow passage into and out of the cell, which is where plasmodesmata developed.
They are called: Plasmodesmata
Cell junctions in plants are called Plasmodesmata while communicating junctions in animal cells are gap junctions
Plasmodesmata in fruit facilitate the transport of nutrients and signaling molecules between cells, which is important for fruit development and ripening. The high number of plasmodesmata connecting cells in fruit may be necessary to support the rapid growth and metabolic processes occurring during the fruit's development and maturation. Additionally, the communication provided by plasmodesmata helps coordinate the ripening process and ensure proper fruit maturation.
Viral particles can move through plasmodesmata either by exploiting existing transport mechanisms within the plant cell or by disrupting the normal functioning of the plasmodesmata to facilitate their own movement. Once inside the plant cell, the viruses can spread to neighboring cells through the plasmodesmata, allowing them to move systemically throughout the plant.
Their cytoplasms are not really connected, but there is a network of cytoskeleton material that gives support to the cells and also interconnects them for structural integrity.
