is cell wall and fungal cell wall are two chief constituents of nucleus

In the cells of fungi, the cellwall is generally composed of chitin, a polysaccharide. The chitin molecules also occur in bundles, like cellulose molecul..

Cell Wall - A cell wall is a characteristic feature of plant cells, bacteria and fungi. The composition however varies in different grou..

The cell wall is present only in plant cells. It is made up of a complex polysaccharide carbohydrate called cellulose. Its function is to give strength and rigidity to the cell. It is non-livin..

It is the outer tough covering around the cell, which provides specific shape and protection to the bacterium. It prevents the cell from swelling and bursting due to osmotic changes. It is composed of a polysaccharide called murein or peptidoglycan. It consists of polysaccharide..

The cellwall of prokaryotes like bacteria is composed of peptidoglycans. Apart from maintaining the shape and size of plant cells, the cell wall is involved in some specific functions such as Protection against the attack of pathogens Providing mechanical support Allow..

Two German biologists M.J.Schleiden (1838) and Theodore Schwann (1839) proposed the cell theory (or cell doctrine), which unified the ideas prevailing at that period on the organisation in plants and animals. The cell theory states that All living organisms a..

Nucleus - Nucleus is the most conspicuous and the largest organelle in the cell. Most cells have a single nucleus and hence they are described as uninucleate. Some cells have two nuclei (binucleate) while a few may be even multin..

The body wall is dermo muscular. It consists of a thin cuticle, and epidermis and musculature. The cuticle is an elastic non-cellular covering. Epidermis is represented by a layer of columnar epithelial cells, represented by supporting cells, glandular cells,..

They are smaller cells associated with the sieve tubes. They have dense cytoplasm and elongated nucleus. It is in contact with the sieve tube cell through pores in the wall..
