If you collected a piece of cell coating found directly external to a eukaryotic plasma membrane, and chemical tests showed that

it was made of cellulose, you would expect to see plasmodesmata if observed with an electron microscope.

Answer:

True.The cellulose must have been conveyed to the surface by the plasmodesmata through  contraction and relaxation of plasmodesmata  openings  for  movements of substances in and out of the cells.

Explanation:

Plasmodesmata are tiny cylindrical channels;  which pass through both the secondary and primary  cell walls of plant. They  are  lined by plasma membranes in plant cells; they are living passages .They connect  the cytoplasm of adjacent cells to one another, to form a continuous network for transport of certain substances across cells; aiding  effective cell communication.

<u>Structurally, they are produced in plant cells  when fragments  of the Endoplasmic Reticum  of the parents cells get trapped in the cell wall meant for formation of  new daughter cells during cell division.</u>

Answer:

True

Explanation:

The observed cell is a plant cell because of presence of cellulose coating on cell membrane. The plasmodesmata are the a layer between cell and cell membrane of plant cells that is porous in nature and enables communication between cell and outside environment. It is obvious to find this with cellulose coating. These plasmodesmatas have same function as gap junction animal cells.

sdas [7]

Answer: Cell membrane is layer which is present in all living cells. It is present under the cell wall but in some cases such as plant cells.

Explanation: It is composed of lipid bilayer and proteins embedded in it. Phospholipids, glycolipids and sterols is the composition. Its function is to protect the cell from extracellular environment. It is semipermeable membrane that js allow only selected molecules to pass.
