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>
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.
The tissue is identified as skeletal muscle tissues. These muscle tissues are long, cylindrical, striated, multi nucleate cells and are arranged parallel to each other
Skeletal muscle is one of three major muscle types other than the cardiac and smooth muscle. Most skeletal muscles are attached to bones by bundles of collagen fibers known as tendons.
For the environmental risk, it is much better to prevent pollution than to deal with it after it has already been made. When you deal with the pollution, it is hard to say that you can eliminate completely. So, prevention is the first strategy.
