cell walls absent in slime molds

Slime Moulds - These are a group of peculiar organisms which share characteristics of fungi and animals. Hence, they are also called as Mycetozoa . In the modern classification they are described as protistan fungi . Most examples of slime moulds are terrestrial and occur in coo..

A lose gelatinous sheath called slime layer is usually deposited around the bacterial cell wall. It is usually composed of polysaccharides. In some bacteria, the slime layer becomes thick due to the presence of some nitrogen compounds and forms a capsule. A c..

The cells are relatively smaller in size compared to mature cells. They are either rectangular or isodiametric in shape. The cells are always compactly arranged, without any intercellular spaces. The cells have a thin cell wall, wh..

Animal cell Plant cell Usually smaller in size Usually larger in size Cell wall is absent. Cellulose in any form is absent Cell wall made up of cellulose is present Cytoplasm is denser, more gra..

The cells are long, narrow, thick and lignified, usually pointed at both ends. The cell wall is evenly thickened with lignin and sometimes is so thick that the cell cavity or lumen is absent. Nucleus is absent and hence the tissue is ma..

The cells which form the permanent tissues, exhibit the following characteristic features: The cells vary in size and shape considerably. They may be spherical or oval or polygonal or irregular in shape. Sometimes the cells may also be elongated. The cells ma..

Collenchyma - It is a type of simple permanent tissue, which is mainly meant for providing mechanical support to the shoot system of a plant. Collenchyma is completely absent in the root. It is composed of elongated cells that are compactly arranged. Sometimes, the cells..

Meristematic tissues are composed of cells that divide continuously. The cells are spherical, oval, polygonal or rectangular The cell wall is thin and made up of cellulose The cells are closely arranged without inter-cellular spaces Cytoplasm is abu..

Epiblema is the outermost covering of the root formed by a single layer of compactly arranged, barrel-shaped parenchyma cells. The cells are characteristically thin-walled since they are involved in absorption of water. A cuticle and stomata are absent...
