The cells of the adaptive immune system are special types of leukocytes‚ called lymphocytes. There are two main types of lymphocytes‚ B cells and T cells‚ which are derived from hematopoietic stem cells in the bone marrow. T cells are involved in cell-mediated immune response‚ whereas B cells are involved in the humoral immune response. The surface of each lymphatic cell has receptors that enable them to recognize foreign substances. There are two major subtypes of T cells: the helper T cell and

History of Cell Theory As we all probably know today‚ every single living being is made up by cells the building blocks of life. As much as we would like to take this fact for granted‚ we cannot help but acknowledge and remember the works and discoveries of earlier scientists which all contributed to our today’s understanding of the cell theory. The cell theory being; all living things are composed of one or more cells‚ cells are organisms’ basic units of structure and function‚ and cells only come

Different Parts of a Plant Cell Plant cells are classified into three types‚ based on the structure and function‚ viz. parenchyma‚ collenchyma and sclerenchyma. The parenchyma cells are living‚ thin-walled and undergo repeated cell division for growth of the plant. They are mostly present in the leaf epidermis‚ stem pith‚ root and fruit pulp. Mature collenchyma cells are living‚ and provide stretchable support to the plant. Lastly‚ sclerenchyma cells (e.g. fiber cells) are hard‚ non-living and

Biogas Plant The Bio-Gas Plant produces gas from the raw materials of human excreta and cowdung. The residue obtained from the plant is used as the food of fish. It is a system to process livestock wastes into safe‚ high-quality‚ efficient organic fertilizer without exhausting greenhouse gases into the air. These gas plants also contribute to safe-keeping and clean environment by preventing bad odor and contamination of the underground. Furthermore‚ they are capable of generating electric power

Another reason I choose to compare the cell to a car is because it seemed to be the easiest one for me to do as compared to a Hogwarts or a city. Doing a house or a prison would have also been fairly easy but they were already picked by the people at my table. That wars why I choose to compare the human cell to an automobile

Over time‚ they have developed unique morphological characteristics in order to survive‚ paying homage to Darwin’s theory of natural selection. How carnivorous plants evolved is still somewhat unknown to botanists‚ this‚ in addition to their morphology
