Structure Of The Cell And Bio Molecules

751 words - 4 pages

The cell, what is a cell means and what is the structure of it. Everyone knows that it’s the smallest particle in any living organism and it’s responsible for anything that happens in our bodies. As there’s no one know what it functions, what is the structure of the cell and what it is consisted from and what does every part in it functions. So, first of all the theory of a cell is that all organisms are formed from cells which is the structural unit of life and they are raised by division of pre-existing cells, as they can be cultured to produce more cells. Although cells are complex and highly organized due to the numerous internal structures and some are membrane organelles while others are not. In addition to that cells carries genetic blueprints and machinery to use it , as the genes are important for the cells to make specific proteins.
History of the cell :
The cell was first discovered in 1665,by an English Physicist and microscopist Robert Hooke. He observed that the empty space might be used for fluid transport in the living organisms, then later on Marcello Malpighi and Nehemiah Grew joined their colleague Hooke in his discovery. As they made a detailed study on the plant cell, presenting the cellular structure from the plant body. Although, Grew has linked the cellular spaces to the gas bubbles in rising bread, observing that they are formed by a similar process and finally they animal cell was also discovered lately due to its thin sections needed to be viewed under a microscope which is more difficult to be prepared than the plant cell, concluding that the animal cell are made of several types of fibers and the various properties of which accounted for the differences among tissues.
Further more, improvements in microscopes helped the researchers a lot to discover more about cells and make it easier to know more details about its structure , what it function, what processes occurs in it, how the cell is developed and what bio molecules it contains and what are they responsible for. Therefore, these days we have two different types of microscopes that helped in making the cell theory which are the light and the electron microscopes.

The structure and composition of the atmosphere

528 words - 2 pages The Earth is surrounded by a blanket of air, which we call the atmosphere. It reaches over 560 kilometers (348 miles) from the surface of the Earth, so we are only able to see what occurs fairly close to the ground. Life on Earth is supported by the atmosphere, solar energy, and our planet's magnetic fields. The atmosphere absorbs the energy from the Sun, recycles water and other chemicals, and works with the electrical and magnetic forces to

690 words - 3 pages alpha helices and beta pleated sheets. The proteins are made so that alpha helices are within the membrane the beta pleated sheets are outside the membrane. This is because cell membranes are made of amphipathic molecules called phospholipids that form a bilayer. The third level involves the interactions between R groups on the amino acids. These could be ionic interactions, covalent bonding or hydrophobic or hydrophilic reactions. A specific type

Another organelles similar shaped as lysosomes are vacuoles. They are larger than lysosomes and are used for storing substances. Food vacuoles are formed when cell takes in food and after the fusio with lysomes , enzymes digest food into smaller molecules that can be used by the cell. Plants cells contains central vacuoles

Helper-T cells, once stimulated by MHC molecules which are associated with foreign peptide fragments and the second signal (IL-1) from the antigen presenting cell, synthesise IL-2 receptors and IL-2 to stimulate themselves. Activated helper-T cells can then help other helper-T cells

A thin melted surficial layer of the Earth was formed due to the heating of congealed atomar layers up followed by their transformation into the molecular
