Chloroplasts are organelles present in plant cells and some eukaryotic organisms. Chloroplasts are the most important plastids found in plant cells. It is the structure in a green plant cell in which photosynthesis occurs. Chloroplast is one of the three types of plastids. The chloroplasts take part in the process of photosynthesis and it is of great biological importance. Animal cells do not have chloroplasts. All green plant take part in the process of photosynthesis which converts energy into

The nucleus is the most obvious organelle in a eukaryotic cell. Virtually all eukaryote cells have a nucleus (red blood cells lose theirs and so are enucleate for most of their life-span of 180 days). It is surrounded by the nuclear envelope‚ a double membrane with contains a large number of pores. Molecules enter and leave the nucleus by these pores. The two lipid bilayers of the double membrane are separated by a gap of 20 to 40 nm‚ called the perinuclear space. The nucleus contains the cell’s

Proteins Are the basic materials of every body cell. Body cells are constantly wearing out. As a result‚ they are continuously in need of replacement Of the six nutrients group‚ only proteins can make new cells rebuild tissue. By the age of 4 years‚ body protein content reaches the adult level of about 18% of body weight. An adequate supply of proteins in the daily diet is essential for the maintenance of health. The word protein is a Greek derivation and means “of first importance”. Composition
