single wall vs double wall

This is a cup - shaped structure which is double walled in the hollow of which is a net work of capillaries called the glomerulu..

It starts from the neck of the Bowman's capsule and it is highly convoluted. It lies in the renal cortex. The wall consists of a single layer of columnar cells bearing a lot of microvilli on the surfac..

The artery that takes blood to the lungs. The arteries divide again and again to form narrower arterioles. The arterioles, branch into very thin tubes called the capillaries. The capillaries are in touch with the tissues and cells. While the walls of the arteries and arterioles have laye..

Epidermis is the outermost covering of the stem. It is represented by a single layer of compactly arranged, barrel-shaped parenchyma cells. Intercellular spaces are absent. The cells are slightly thick walled. Epidermis shows the presence of numerous multicellular projecti..

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. Some of the epiblem..

The human circulatory system is a closed circulatory system. The blood flows in closed vessels without coming in direct contact with the cells of the body. The walls of the blood vessels are made up of three layers: Inner endothelium - single layer of cells Tunica media - made o..

Blood Vessels - The human circulatory system is a closed circulatory system. The blood flows in closed vessels without coming in direct contact with the cells of the body. The walls of the blood vessels are made up of three layers: Inner endothelium - single layer of cells Tunic..

The cells of all living organisms consist of protoplasm, which is bound by a cell membrane. Prokaryotic cells and cells of algae, fungi and higher plants contain a cell wall outside the cell membrane. Some protozoans cells show the presence of a cell coat outside the cell membrane. T..

Summary - The cells of all living organisms consist of protoplasm, which is bound by a cell membrane. Prokaryotic cells and cells of algae, fungi and higher plants contain a cell wall outside the cell membrane. Some protozoans cells show the presence of a cell coat outside the cell membra..

Animal Cell Plant Cell Usually smaller in size. Usually larger in size. Cell wall absent. Cellulose in any form is absent. Cell wall made up of cellulose is present. Cytoplasm is denser, more granular and occupies most of the space in the cell. Cytoplasm is pu..
