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 in plants equals to what in animals?
There is no exact equivalent, but a gap junction is the closest thing an animal cell has to plasmodesmata.
The purpose of plasmodesmata is to?
communicate with other cells
Can see the plasmodesmata in the persimmon but not in the Elodea?
Yes.
What are plasmodemata?
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
What are small channels that form across the plasma membranes of adjacent cells?
plasmodesmata
What color is a plasmodesmata?
a plasmodesmata is usually brown and button shaped
Plasmodesmata in plants equals to what in animals?
There is no exact equivalent, but a gap junction is the closest thing an animal cell has to plasmodesmata.
The purpose of plasmodesmata is to?
communicate with other cells
Can see the plasmodesmata in the persimmon but not in the Elodea?
Yes.
What attaches skin cells to the extracellular matrix by?
Plasmodesmata
Connection between two plant cells?
Plasmodesmata.
What junctions are found only in plant cells?
plasmodesmata
What passage water through the cell membrane?
Plasmodesmata.
What the purpose of plasmodesmata?
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.
What are open channels in plant cell wall?
They are called: Plasmodesmata
How are the plasmodesmata of plant cells and commicating junctions of animal cell similar in function?
Cell junctions in plants are called Plasmodesmata while communicating junctions in animal cells are gap junctions
Do plasmodesmata connect the cytoplasms of one plant cell to another?
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.
