Lysosomes, peroxisomes and vacuoles

- What is the volvox? Observed microscopically, the body looks like a small concave area of about 1mm in diameter, composed of hundreds of green chlorophyll cells: is what the researchers called a colony. Each such cell has a nucleus, a cytoplasm, a chloroplast, sensitive to changes in light intensity and two flagella (vibrating two long tails), which ensures coordinated movement of the colony displacement eyespot. Each of these cells is able to lead an independent life. - Branch of functions between the elements forming the alga volvox hkia The set of cells that form the Volvox is however not only a group of cellular elements, hkia but a system in which it is possible to identify a rudimentary division of functions between the different elements is formed and some differentiation in the structure of the cell units. Algae seems to present an upper end and a lower end, the latter consisting of thicker cells that reproductive functions are assigned. In addition, the movement of flagella is different in a dark or bright atmosphere, since the colony is attracted by light. hkia Playback may take place either by fertilization between elements of the sexually differentiated colony as division of cells located in the lower pole. These, after increasing in size towards the center generated many daughter cells.

Biology is a scientific discipline that aims to study every living form, either from the point of view of the organizational structure and evolution either from the intrinsic relationship with the environment and with other agencies. Born as a descriptive science, modern biology today encompasses areas of applied hkia research particularly important, such as molecular or cell biology. More specifically, biology deals with the description of the organisms and their parts (anatomy, histology and cytology), its classification (systematic) of their internal structure (biochemistry and molecular biology), the functioning of vital processes ( physiology and pathology), the development and evolution of the species (embryology, evolution and science of genetics).
