This is a prominent, spherical or oval structure found at the centre of the cell. It is the controlling centre of all cell activities and has been described as the brain of the cell. It regulates all metabolic and hereditary activities of the cell. The nucleus is composed of the following structur..

They number 5 million per cubic mm in adult males and 4.5 million per cubic mm in adult females. Their number is higher in early infancy. The cells are composed of a network of fats and proteins between which are enmeshed numerous pigments called the haemoglobin which give the blood..

It forms the green expanded portion of the leaf. In the dicot leaf, the lamina has a central midrib running from the base to the apex. The lamina on either side produces veins which in turn produce veinlets, to form a network of veins. Hence the venation is described as reticulate type. ..

Chromosomes (chroma = colour, soma = body) are tiny thread-like structures found in the nucleus of a cell. In a non-dividing cell they appear as a chromatin network while during cell division they become condensed to form short and thick chromosomes. Chromosomes are unique cell stru..

A kidney receives the blood from the renal artery that arises from the dorsal aorta. In the kidney, the renal artery divides and subdivides to send an afferent arteriole into each Bowman's capsule. Here the afferent arteriole forms a bunch of about 50 parallel capillaries called glomerulus. T..
